ABB 3BHE021083R0101 Drive Power Board

Feature & Principle

It is ABB XVC770BE101 supporting isolated power board, used in ACS6000 high-power medium voltage frequency converter. It provides multi-channel stable isolated power supply for IGBT gate drive circuit. Cooperate with the drive board to receive optical fiber PWM signal, complete IGBT turn-on and turn-off control, integrate DESAT short-circuit protection, active Miller clamp and fault feedback function, improve the safety and stability of power devices. This spare is mainly used for maintenance replacement of old medium voltage drive system.
