MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200UPSAG1A DS200UPSAG1AGD power supply board provides regulated DC power for GE Mark V turbine control systems. This board accepts a high-voltage DC input and generates multiple low-voltage outputs. You will find this power supply in main control cabinets and drive panels. Its rugged design supports continuous industrial operation.
Board Function and Power Conversion Core
This power supply board uses a buck converter topology for voltage step-down. Consequently, it achieves efficient power conversion with minimal heat loss. The GE DS200UPSAG1A DS200UPSAG1AGD generates three independent output voltages simultaneously. Moreover, built-in overcurrent protection safeguards downstream circuits. You can rely on this board for critical control system power.

Power Management and Energy Storage
The unit holds 8200 µF of bulk capacitance on its input stage. Therefore, it maintains output stability during input voltage dips. This board replaces the DS200UPSAG1AGD version without any mounting modifications. Simply remove the old power supply and insert this one. GE designed this board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Six PCB layers separate high-voltage traces from low-voltage circuits. Three connectors handle all input, output, and monitoring signals. The GE DS200UPSAG1A DS200UPSAG1AGD also includes independent regulation for each output channel. Accordingly, a short on one output does not affect the others. This feature proves essential for mixed analog and digital loads.
Cooling and Protection Features
Two heatsinks and one brushless fan provide active cooling. The fan activates automatically when internal temperature exceeds 50°C. The GE DS200UPSAG1A DS200UPSAG1AGD delivers 15 ms of hold-up time after input loss. Consequently, the main controller can save critical data before shutdown. Four status LEDs indicate each output’s condition clearly.
Always verify input polarity before connecting DC power. The board includes reverse polarity protection on the input. The GE DS200UPSAG1A DS200UPSAG1AGD works with all GE Mark V control systems. Regular cleaning of the fan intake ensures maximum cooling efficiency. Proper airflow around the heatsinks guarantees full rated output current.
