The low ripple 800A 8V rectifier for PCB plating is a typical unit in modern surface treatment lines. Its AC input first passes through a rectification and filtering stage, where it is converted into an intermediate high‑voltage DC bus. This DC bus is then inverted by the inverter stage​ into approx. 30 kHz high‑frequency AC. The high‑frequency AC is stepped down by a high‑frequency transformer​ and rectified/filtered by a high‑frequency rectifier circuit​ to produce the required low‑voltage output. A control circuit​ continuously samples the output voltage and current; these signals are fed back in a closed‑loop control scheme​ to generate pulse‑width modulation (PWM)​ signals. The PWM signals regulate the inverter, ensuring stable output voltage and current—critical requirements for precision electroplating applications.

» Product Applications

Electroplating rectifiers are widely used across diverse surface treatment applications. Key areas include PCB manufacturing, where precision current control is critical for circuit board plating; hard chrome plating, requiring high ripple and stability for wear-resistant coatings; and general decorative and functional plating such as copper, nickel, zinc, gold, tin, and silver finishing.

Whether your application calls for a PCB plating rectifier, a hard chrome plating rectifier, or a multi-purpose unit for various metal finishing, our rectifiers deliver stable DC output, high efficiency, and reliable performance tailored to each process requirement.

The ​Electroplating Rectifier Power Supply employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.

» Product Applications

Electroplating rectifiers are widely used across diverse surface treatment applications. Key areas include PCB manufacturing, where precision current control is critical for circuit board plating; hard chrome plating, requiring high ripple and stability for wear-resistant coatings; and general decorative and functional plating such as copper, nickel, zinc, gold, tin, and silver finishing.

​› Nickel Plating

Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.

Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.

​› Gold Plating

Purpose: Optimizes conductive contact impedance and signal transmission.

Key: High stability but costly.

​› Palladium-Nickel Plating

Purpose: Superior signal transmission and wear resistance vs. gold.

Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.

​› Tin-Lead Plating

Purpose: Improves solderability.

Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.

​› Silver Plating

Purpose: Best conductivity and signal performance.

Note: Conducts even when oxidized but tarnishes over time. Higher cost.

​Selection Criteria

Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.

» Elements of Electroplating

› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.

› Anode

​Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution.

​Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.

› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.

› Plating Tank

Materials: Must resist corrosion and temperature fluctuations (e.g., polypropylene, titanium alloys).

Role: Stores solution and maintains stable plating conditions.

› Rectifier

Converts AC to DC power to drive electrolysis.

Adjust voltage/current to control deposition speed and coating thickness.

› Auxiliary Equipment

​Filters: Remove impurities from the solution.

​Heaters: Maintain solution temperature.

​Stirrers: Ensure uniform mixing.

Water treatment refers to the process of removing unwanted substances from water for industrial and domestic purposes via physical and chemical methods. General-purpose water treatment power supplies are dedicated devices that generate the electric field required for chemical water treatment processes, and water treatment rectifiers serve as the core power equipment in this sector. For example, a 2500A 25V rectifier for wastewater treatment is a typical high‑power unit used in large‑scale chlorination systems, delivering the precise DC output required for effective disinfection.

Among various water treatment technologies, water treatment rectifiers act as critical equipment with irreplaceable functions. By adjusting current characteristics, they deliver stable and reliable power supply for water treatment procedures, thus boosting overall processing efficiency.

What a water treatment rectifier essentially does is take alternating current (AC) and turn it into direct current (DC). The AC coming in gets rectified and filtered, producing a higher DC voltage. That DC then goes through a frequency conversion stage that turns it into high-frequency AC at about 15 kHz. This high-frequency AC is passed through a high-frequency transformer to the secondary side, where it gets rectified and filtered once more to give you the output voltage you need. A control circuit samples both output voltage and current, then uses closed-loop feedback to generate PWM signals that regulate the power conversion stage, keeping the rectifier’s output steady.

Application Scenarios of Water Treatment Rectifier

Liyuan Haina water treatment rectifiers are widely deployed across the water treatment industry, including industrial and domestic sewage treatment, electrolytic treatment of electroplating wastewater, precious metal recovery, seawater desalination, sodium hypochlorite electrolysis and other applications.

Electrocoagulation Water Treatment
This technology uses the DC field from the rectifier to dissolve the anode, releasing metal ions into the water. Those ions meet up with hydroxide ions and form flocculants—aluminum hydroxide is a good example—which then pull out suspended solids, pigments, and heavy metals. In a typical electrocoagulation system, the rectifier powers the electrodes inside the tank, and the water gets cleaned up through these electrochemical reactions.

Electrolytic Wastewater Treatment
Industrial wastewater contains hazardous pollutants including heavy metal ions and organic compounds. Driven by current from water treatment rectifiers, contaminants undergo redox reactions on electrode surfaces and are broken down. In hardware processing and surface finishing wastewater treatment, rectifiers enable recovery and reuse of valuable metal ions such as copper, gold and silver.

Seawater Desalination
In seawater desalination processes such as electrodialysis and reverse osmosis, water treatment rectifiers provide stable DC power to facilitate seawater desalination.

Ballast Water Treatment
Ship ballast water must be treated to prevent invasive marine species. Rectifiers electrolyze seawater to produce disinfectants like sodium hypochlorite for ballast water sterilization.

Electrodeionization (EDI) Systems
EDI is an advanced deep desalination technology for ultrapure water production. Water treatment rectifiers power EDI systems, removing ionic impurities from water via electrochemical reactions to yield high-purity water.

Sodium Hypochlorite Generation
Rectifiers electrolyze seawater or brine, and the sodium hypochlorite produced this way is then used as a disinfectant across various water treatment applications.

General-purpose water treatment power supplies are dedicated devices that generate the electric field required for chemical water treatment processes, and water treatment rectifiers serve as the core power equipment in this sector. For example, an SCR rectifier 500A ±100V for water treatment and electrolysis is a typical high-power model used in large-scale chlorination systems, delivering the precise DC output needed for effective disinfection.

Among various water treatment technologies, water treatment rectifiers act as critical equipment with irreplaceable functions. By adjusting current characteristics, they deliver stable and reliable power supply for water treatment procedures, thus boosting overall processing efficiency.

What a water treatment rectifier essentially does is take alternating current (AC) and turn it into direct current (DC). The AC coming in gets rectified and filtered, producing a higher DC voltage. That DC then goes through a frequency conversion stage that turns it into high-frequency AC at about 15 kHz. This high-frequency AC is passed through a high-frequency transformer to the secondary side, where it gets rectified and filtered once more to give you the output voltage you need. A control circuit samples both output voltage and current, then uses closed-loop feedback to generate PWM signals that regulate the power conversion stage, keeping the rectifier’s output steady.

Advantages of Water Treatment Rectifier

High Efficiency & Stable Performance
Based on the operational data of tens of thousands of installed units, products deliver outstanding reliability when installed and operated in compliance with specifications. They maintain stable long-term operation and consistently guarantee effective water treatment results.

Eco-Friendly
Water treatment rectifiers eliminate the need for traditional chemical additives in water treatment, enabling truly natural and environmentally friendly treatment processes.

Multi-Layer Protection
Equipped with comprehensive protection mechanisms including overcurrent, phase loss, overtemperature and other safety functions.

Intelligent Control
All rectifiers support local display and operation on the unit itself, as well as remote monitoring and control via PLC. Each unit is fitted with an RS485 communication module. Operating status (running, forward operation, fault, local/remote mode) can be displayed locally and transmitted to the PLC; remote control is also available via 4–20 mA analog signals.

Features of Water Treatment Rectifier

Adjustable Output
Output regulation range: rated voltage 0–100% continuously adjustable, rated current 0–100% continuously adjustable; voltage and current can be regulated independently.

Remote Control Capability
All rectifiers support local display and operation as well as remote PLC monitoring and control, equipped with RS485 communication modules. Each unit integrates local and remote PLC functions including voltage/current adjustment, output voltage/current display, start/commutation control. Real-time operating status (running, forward operation, fault, local/remote mode) is shown locally and uploaded to the PLC; 4–20 mA analog signals are adopted for remote control.

Soft Start & Soft Stop
Built-in soft start and soft stop functions; soft start and soft stop durations can be set on the on-site cabinet.

Reserved Interlock Terminals
The rectifier features interlock functions with reserved terminals for connection to passive normally open contacts inside the client’s control cabinet. The power supply will suspend startup and output when this signal circuit is disconnected.

Application Scenarios of Water Treatment Rectifier

Liyuan Haina water treatment rectifiers are widely deployed across the water treatment industry, including industrial and domestic sewage treatment, electrolytic treatment of electroplating wastewater, precious metal recovery, seawater desalination, sodium hypochlorite electrolysis and other applications.

Electrocoagulation Water Treatment
This technology uses the DC field from the rectifier to dissolve the anode, releasing metal ions into the water. Those ions meet up with hydroxide ions and form flocculants—aluminum hydroxide is a good example—which then pull out suspended solids, pigments, and heavy metals. In a typical electrocoagulation system, the rectifier powers the electrodes inside the tank, and the water gets cleaned up through these electrochemical reactions.

Electrolytic Wastewater Treatment
Industrial wastewater contains hazardous pollutants including heavy metal ions and organic compounds. Driven by current from water treatment rectifiers, contaminants undergo redox reactions on electrode surfaces and are broken down. In hardware processing and surface finishing wastewater treatment, rectifiers enable recovery and reuse of valuable metal ions such as copper, gold and silver.

Seawater Desalination
In seawater desalination processes such as electrodialysis and reverse osmosis, water treatment rectifiers provide stable DC power to facilitate seawater desalination.

Ballast Water Treatment
Ship ballast water must be treated to prevent invasive marine species. Rectifiers electrolyze seawater to produce disinfectants like sodium hypochlorite for ballast water sterilization.

Electrodeionization (EDI) Systems
EDI is an advanced deep desalination technology for ultrapure water production. Water treatment rectifiers power EDI systems, removing ionic impurities from water via electrochemical reactions to yield high-purity water.

Sodium Hypochlorite Generation
Rectifiers electrolyze seawater or brine, and the sodium hypochlorite produced this way is then used as a disinfectant across various water treatment applications.

Types of Water Treatment Rectifier

High-Frequency Rectifiers
Efficient, energy-saving, precise, and reliable—these rectifiers have found their way into wastewater treatment, seawater desalination, ballast water treatment, and sodium hypochlorite production from seawater or brine. They handle conventional electrochemical processes like electrocoagulation, electrolytic oxidation, and electrochemical disinfection just fine, with output voltages typically landing in the 10–100 V range.

Silicon Controlled Rectifier (SCR) Rectifiers
These are what you turn to when the job calls for higher voltages—high-voltage electrochlorination, for instance.

EDI Power Rectifiers
Custom-developed for Electrodeionization (EDI) systems, capable of precise regulation of output voltage and current with a typical DC voltage range of 50–300 V. These rectifiers deliver stable DC electric fields for EDI modules, with core capabilities of accurate voltage control, current density adjustment and polarity switching to ensure efficient and steady EDI operation. They are extensively applied in EDI systems producing drinking water, industrial process water, pharmaceutical-grade water and electronic-grade ultrapure water.
