Description
🔹 Product Description
The GE IS200DAMCG1A, also identified as IS200DAMCG1ACB, is a DAMC Gate Drive Amplifier and Interface Board used in GE Mark VI Innovation Series drive systems. The board provides the final gate-drive amplification stage between the control rack and the IGBT power switching devices in a low-voltage drive. The DAMC configuration is associated with a 250A drive frame rating and connects directly to the IGBT gate, collector, and emitter terminals as well as the IS200BPIA Bridge Personality Interface Board. Four front-board LEDs labeled UON, UFF, LON, and LFF provide local switching-status indication. The board uses a +15 V / -7.5 V gate-drive supply and is intended for maintenance and replacement of compatible GE drive hardware.
