151X1235DB10SA01 GE

151X1235DB10SA01 is the PCM (Power Control Module) regulator unit for the GE EX2100e digital generator excitation control system. This integrated power conversion hardware serves as the core power-execution component for synchronous generator excitation loops in power plant applications. It receives excitation command signals from the EX2100e controller board, implements high-speed IGBT-based PWM modulation, and delivers regulated DC excitation current to generator rotor windings.

151X1235DB10SA01

HS Code: 85389000 (parts for electrical control apparatus, for reference only, subject to local customs verification)
Operating Temperature: 0 °C to +55 °C cabinet ambient operating range; storage temperature from -40 °C to +85 °C, performance derating required above 50 °C
Input Voltage: 90-280 Vrms, single-phase or three-phase AC input, input frequency 45-480 Hz
Output Voltage: 0-250 VDC continuous
Output Current: 35 A DC continuous rated output; 70 A DC short-time over-excitation for 10-second duty cycle
Function: Executes pulse-width-modulated power conversion for generator excitation regulation under EX2100e system control. It converts field-side AC power into adjustable DC excitation output for synchronous generator rotor circuits. Built-in monitoring circuits detect over-current, over-voltage, over-temperature and internal power device faults, and trigger protective shutdown upon fault detection. It communicates with the EX2100e controller via internal interfaces to feedback real-time output status and fault alarms. Designed for panel mounting inside generator control cabinets, it includes heavy-duty terminal blocks for high-power wiring and integrated heat-sink assembly for thermal dissipation. It is widely deployed for excitation control of steam turbine and gas turbine generator sets in utility power generation plants.
Humidity Rating: 5-95 % non-condensing relative humidity for operation.
Installation: Panel-mount design for industrial control cabinet installation, equipped with high-current screw terminal connections for power wiring.
