20000A 18V water-cooled hard chrome rectifier with automatic commutation (N+1 parallel operation)

Product Features

1. This product is a special power supply based on a standard high-frequency rectified electroplating power supply, with an output voltage of 6-18V. It possesses the functions of a standard electroplating power supply and is ideal for special electroplating surface treatments such as hard chrome plating. 2. It features multi-step stepped power supply, multi-step soft-start time setting, automatic reset, and other functions to meet different process requirements. 3. The power supply has voltage and current stabilization or current and voltage stabilization functions, with control and display accuracy ≤1%. 4. The equipment has multiple protection functions including output overcurrent, over-temperature, and input phase loss. The product is stable and reliable, with a reasonable internal structure and all electronic components sealed, reducing the impact of the external environment on the internal components. 5. The control system can be selected from digital control, analog control, or RS485 communication control, and can also be equipped with a 4-20mA, 0-10V standard control signal interface.

Introduction to Automatic Reversing Switches

Gaohui automatic reversing switches are DC power supply positive and negative terminal switching devices, widely used in switching power supply commutators in the electrolysis and electroplating industries. Current high-power switching power supplies lack positive and negative terminal reversing functionality; if reversing is required, manual switching of the positive and negative wires is necessary after stopping the machine, which is cumbersome. To overcome the shortcomings of existing technology, Gaohui provides a simple, fast, and highly safe pneumatic automatic reversing switch for switching power supplies.
