The Polarity Reversing Chrome Rectifier from Gaohui Rectifier switches between positive and negative output at 20000A and 18V. This Polarity Reversing Chrome Rectifier runs advanced etch-plate cycles for demanding hard chrome work. Furthermore, the Polarity Reversing Chrome Rectifier manages the full 20000A load during both polarities. Consequently, platers achieve premium adhesion and deposit quality on critical parts. Moreover, positive-negative cycles facilities select this Polarity Reversing Chrome Rectifier for its water cooled design and 20000A capacity that keeps deposition rates predictable. Consequently, production planners factor it into daily schedules without derating concerns.
Cooling: Water Cooled | Application: Positive-Negative Cycles | Ripple: ≤5% | Interface: RS485/PLC
The 20000A 18V rectifier serves very large hard chrome tanks above 10000L with positive-negative cycling programs. It is ideal for crankshafts, landing-gear components, heavy rolls and tool-steel dies. For example, an aerospace supplier can execute precise reverse-etch cycles on large landing-gear parts. Furthermore, the 18V output supports longer racks and more resistive electrolytes. Moreover, the 380V output range provides useful headroom for bus-bar losses, contact resistance and cooler electrolytes. In addition, the RS485, PLC port allows remote monitoring.
Moreover, polarity changes are executed with minimal delay, protecting deposit integrity. In addition, PLC communication allows the cycles to be synchronized with line automation. Consequently, this rectifier delivers the control depth that premium hard chrome demands. Moreover, operators appreciate the straightforward layout and clearly marked controls on this Polarity Reversing Chrome Rectifier. Finally, the service team at Gaohui Rectifier responds to spare-part requests quickly, which keeps the line running.
