This power supply board provides regulated DC voltages for GE Mark V turbine control systems. It converts incoming AC power into stable outputs for logic and field circuits. The DS200UPSAG1AFD ensures continuous operation of critical speed and temperature monitoring functions.
Core Electrical Specifications
The board accepts an input voltage range of 85–264 V AC at 47–63 Hz. It produces three independent output rails at 5 V DC, 15 V DC, and -15 V DC respectively. The 5 V rail delivers 12 A for powering microprocessor and memory components. Furthermore, the ±15 V rails supply 2.5 A each for analog signal conditioning circuits. The unit achieves 85% typical efficiency across its full load range.
Connectivity and Diagnostic Interface
The front panel features a 16-pin terminal block for AC input and DC output connections. This block accepts solid or stranded wires from 0.5 to 2.5 mm². Additionally, the DS200UPSAG1AFD includes a 10-pin header for remote voltage monitoring and status reporting. A green LED indicates normal operation, while a red LED signals a fault condition. The board also offers a 5 V standby output for powering external monitoring devices.
Energy Storage and Hold-Up Capability
An internal capacitor bank stores 220 joules of energy for ride-through requirements. This storage maintains full output regulation for 25 milliseconds following an AC line dropout. Consequently, the board prevents microprocessor resets during momentary power disturbances. The unit also features inrush current limiting to protect input rectifiers from surge damage.
Mechanical Specifications and Environmental Ratings
The PCB measures 28.0 x 18.0 x 3.5 centimeters and weighs approximately 1.2 kilograms. Its rugged construction uses high-temperature FR-4 material with a protective conformal coating. The board mounts vertically within GE’s standard Mark V rack enclosures. Moreover, the DS200UPSAG1AFB operates reliably across temperatures from -20°C to +65°C.
