GE Mark V DS200SDCIG1AFB DC POWER SUPPLY AND INSTRUMENTATION BOARD
Product Description:
The GE DS200SDCIG1AFB is a Power Supply Board for GE’s Mark V Turbine Control System and DC2000 drive control systems. It acts as an interface to DC2000 drives, enabling non-reversing/non-plugging (NRX) motor control for unidirectional motor operation. As a Group 1 Mark V component, it has three revisions: two functional, one artwork and domestic manufacture.
Key hardware includes power circuits ----armature SCR gating, motor field control, fuses---FU1-FU3, FU5-FU6 for 115V AC/signal power, two jumpers, and SW1. It offers two versions: SDCIG1 that internal 10A NRX field control with 15A fused outputs, line reactor, snubbers. And SDCIG2 external field supply management. Power supplies include ±5V/±15V/±24V DC and 115V AC; it uses thyristor-diode bridges for field current regulation.
Features:
NRX Motor Control: Enables single-direction motor operation for DC2000 drives, boosting reliability in consistent, unidirectional applications.
Dual-Version Flexibility: SDCIG1 (integrated 10A field control) suits self-contained setups; SDCIG2 (external field management) offers customization for external systems.
Comprehensive Protection: Fuses with neon blow indicators, AC/DC snubbers, and line reactors guard against voltage spikes, noise, and component damage.
Precise Power Regulation: Thyristor-diode bridges and dedicated power circuits (±5V/±15V/±24V DC, 115V AC) ensure stable field current and system power.
