ABB HESG112802M14 / HESG324008 / HE502032-1735 / 216GW62

Product Overview

ABB HESG112802M14 (also marked HESG324008, HE502032-1735, 216GW62) is an IGCT gate drive unit, designed for ABB ACS6000 series medium voltage converters. This unit is responsible for triggering IGCT power semiconductor devices and monitoring the working status of the power stack.

It receives optical trigger signals from the main control board, converts optical signals into powerful gate drive pulses to turn on/off the IGCT. Meanwhile, it continuously monitors device current, voltage and fault status. Once abnormal conditions such as overcurrent occur, it immediately sends fault feedback via optical fiber to the controller for protection action. Optical isolation separates low voltage control circuits and high voltage power side to resist strong electromagnetic interference inside high-power converter cabinets. It is a critical discontinued spare component used for overhaul and repair of legacy ACS6000 medium voltage drives in heavy industrial sites.
