GE DS200IMCPG1C
The GE DS200IMCPG1C is an IAC2000I power-supply interface board for Mark V turbine control drives. It serves as the electrical junction between the SDCC control card and the IGBT power stack, routing 24 V logic power, gate-drive voltages, and status signals.
-
Product Type: Power-Supply Interface Board (IAC2000I)

-
Mounting: 4-hole chassis mount (112 mm × 75 mm pattern)
-
Weight: 0.47 kg (1 lb)
-
Conformance: Domestic GE build, normal assembly, C-revision firmware
-
Working Principle: Takes 24 VDC from the battery charger, filters it, splits out ±15 V for IGBT gate drives, and routes armature & field feedback back to the SDCC. The eight fuses protect every rail — when a short occurs, only the relevant fuse blows rather than damaging the entire SDCC.
-
Functional Highlights:
-
Modbus TCP/IP face-plate port for real-time volts, amps, and fuse status into plant DCS without extra gateways
-
Critical for DC2000 crane drives and similar Mark V applications where gate power stability directly impacts IGBT lifetime
-
-
Installation Requirements: Use exactly the specified 5×20 mm, 250 V, 2 A fast-blow ceramic fuses — fuse mismatch is prohibited.
-
Usage Notes: Ensure proper 24 VDC input polarity; verify gate-drive output compatibility with the connected IGBT modules before energizing.
