Built to handle continuous heavy-load electrochemical operations, the Heavy-Duty Water-Cooled Synchronous Rectifier delivers adjustable 4000A 12V low-loss DC power. Meanwhile, robust water cooling dissipates massive heat during non-stop full-load operation.
The Heavy-Duty Water-Cooled Synchronous Rectifier supplies efficient DC power built for large tank electroplating, metal electrowinning and heavy-duty metal surface treatment. Unlike conventional diode rectifier units, this synchronous design cuts conduction losses and slows thermal degradation under continuous peak-current operation. For example, it can maintain stable performance when workpiece batches or bath ion concentrations keep changing. Many air-cooled power supplies cannot dissipate heat fast enough under such extreme high-current conditions. As a result, they will trigger thermal shutdown and cannot support round-the-clock industrial manufacturing. Unnecessary power loss increases electricity cost and accelerates aging of internal components. These issues raise ongoing operation expenses and shorten the total service life of the machine.
The Synchronous Rectifier supports full stepless adjustment ranging from 0‑4000A and 0‑12V. It fits power requirements for oversized plating tanks, metal electrowinning and other low-voltage ultra-high-current electrochemical workflows. In addition, its high-efficiency water-cooled thermal system removes heat steadily during extended full-load cycles. It maintains ideal operating temperature even under continuous peak-current running. Its closed-loop synchronous control holds precise DC output despite variable load changes. It reduces power consumption and stabilizes bath working status. Furthermore, multi-layer safety safeguards protect internal hardware against overload, over-temperature and unexpected short-circuit events throughout long production shifts.

In fact, many high-current industrial rectifiers adopt traditional diode circuit designs. They generate excessive heat and waste more energy during continuous heavy-load operation. Even so, the Synchronous Rectifier works perfectly for large metal finishing factories and metal recovery plants. Many industrial facilities run non-stop production with changing load conditions, and this unit adapts well to these real working scenarios. Our testing team carries out full-load and thermal stress testing for every unit before delivery. Therefore, each unit maintains stable energy-saving performance across repeated production batches.
Our closed-loop regulation system reacts rapidly to minor output deviations. Changing workpiece loads and cooling water inlet temperature create these small fluctuations. It keeps highly accurate current and voltage output under diverse working states. As a result, you cut energy waste and reduce long-term operating costs. The unit can store multiple groups of production process parameters. Operators pull up verified process recipes quickly. This action shortens equipment setup cycles and improves overall workshop productivity.
The reinforced integrated cabinet reserves dedicated ports for water pipeline installation. It suits fixed-installation mass-production workshop environments. You only need to arrange standard water inlet and outlet pipelines for regular operation. It effectively lowers hardware failure risks caused by overheating. Meanwhile, it operates reliably for long hours inside humid, corrosive industrial workshop surroundings.
