Input parameters: Three-phase AC 380V ± 10% 50Hz
In line with the national power quality standards
Output parameters: DC 780V 700A
Output mode: Common DC output
Cooling method: Air or Water cooling
Power supply type: Silicon controlled rectifier
Application Industry: Salt water, potassium salt electrolytic caustic soda, potassium alkali, sodium, potassium chloride electrolytic potassium chlorate, potassium permanganate.
We designed this 700A 780V rectifier specifically for caustic soda electrolysis and other demanding processes requiring reliable high-voltage DC power.
Thanks to silicon carbide (SiC) components, it reaches efficiency levels around 96–97%, lowering your power consumption during long-term operation.
Each unit can supply up to 60kW, and offers both air and water cooling options to fit various industrial setups.
