ABB 3BHB017688R0001 Power Module

Product Description

ABB 3BHB017688R0001, internal designation IPS21‑35AD, is an IPS21‑series Isolated Power Supply module dedicated for ABB medium‑voltage IGCT converters, compatible with ACS6000 and ACS5000 medium‑voltage drives. This unit provides galvanically‑isolated regulated power for IGCT gate‑driver circuits. High‑voltage isolation between input and output suppresses common‑mode interference and ensures safe, reliable operation of power‑semiconductor drive loops. Designed as a slot‑mount card inside converter cabinets, it serves as OEM spare part for drive‑system maintenance, retrofit and direct replacement for IGCT power‑unit assemblies.
