Application
WHFB series high frequency electrolytic rectifiers are applicable for nonferrous metal electrolysis refining (copper, zinc, nickel, lithium, lead, etc.), copper electrolysis, aluminum electrolysis, rare earth electrolysis, salt water electrolysis, chemical electrolysis, etc. This high frequency rectifier can also be used for electrolytic polishing, electrolytic brightening, electrochemical polishing, electrolytic oxidation, plasma electrolytic oxidation, electrolytic iron, electrodeposited copper foil, electrolytic foil, electrolytic copper foil, etc.
Features
1. WHFB series high frequency electrolytic rectifiers adopt DSP for digital control.
2. This high frequency rectifier adopts SCR 6-pulse rectification mode. There are 6KV, 10KV, 20KV and 35KV incoming lines for voltage regulation.
3. Double channels are available for hot spare, which makes this SCR power supply switch without stop and disturbing.
4. Local control and remote control can be converted mutually. The high frequency electrolytic rectifier can choose constant current or constant voltage operation mode.
5. WHFB electrolytic high frequency rectifier use CAN BUS, PROFIBUS, INDUSTRY ETHERNET, RS485 and RS232 optical fiber for communication.
6. The rectifier transformer of this electrolysis power supply can carry out 9 to 27 grade on-load voltage regulation (coarse adjustment) and secondary side SCR regulates phase shifting voltage (accurate adjustment).
