Hardware Specifications Parameter Specification Model DS200GDPAG1ALF Brand GE Origin USA Weight 0.59 kg Operating Temp -30 deg C to +65 deg C Power Consumption ~69 W at full load Input Voltage Range 100 VDC to 140 VDC (125 VDC nominal) Switching Frequency 80 kHz fixed with slope compensation Output Channels 6 isolated, non-regulated 24 VDC outputs Output Current 0.6 A per channel (2.5 A total combined maximum) Isolation Voltage 2500 V RMS (primary to secondary) Efficiency ~87% at 80% rated load Hold-up Time 25 ms at full load Primary Topology Single-ended forward converter with reset winding Onboard Capacitance 4 x 470 uF 200 V bulk capacitors, 14 ceramic decoupling capacitors Physical Interface 40-pin backplane connector, 8-pin output header Power Electronics Isolation & Firmware Flash Compatibility The board implements a single-ended forward converter topology driven at a fixed 80 kHz switching frequency to manage high-voltage isolation boundaries. Onboard magnetic amplifier regulation maintains cross-regulation tolerances within +/-10% across unbalanced channel loads. Integrated soft-start circuits restrict initial inrush currents to protect primary DC bus lines. Board backplane logic routes through a 40-pin header, interfacing directly with Mark V card guides to preserve signal integrity and eliminate backplane bus communication velocity degradation across adjacent control hardware. Frequently Asked Questions Q: What precautions should be taken regarding hot-swapping the DS200GDPAG1ALF during system operation? A: Hot-swapping this board while the primary 125 VDC bus is energised is strictly prohibited. Disconnecting or seating the 40-pin backplane connector under load induces arc flash risk and can damage primary power semiconductors due to uncontrolled voltage transients across the 24 VDC outputs. Q: How does the power supply handle brief input voltage drops on the 125 VDC bus? A: The board incorporates four 470 uF, 200 V bulk capacitors that store energy to maintain a 25 ms hold-up time at full load, preserving stable 24 VDC output voltages during momentary voltage dropouts. Q: What is the dielectric breakdown limit between the primary input logic and the secondary output header? A: The transformer and physical layout provide galvanic isolation rated to 2500 V RMS continuously between primary power circuits and secondary output lines. Field Installation Guidelines ESD Protection: Wear a grounded wrist strap connected to cabinet earth ground before removing the board from its conductive protective bag. Power De-energization: Ensure the main 125 VDC feeder circuit breaker is locked out and verified at 0 VDC with a calibrated meter prior to installation or maintenance. Mechanical Insertion: Align the board edges strictly with the card guide rails inside the Mark V rack enclosure. Slide the unit inward smoothly until the 40-pin connector mates securely with the backplane header. Wiring Integrity: Secure the secondary output connections using the 8-pin header. Ensure signal wires are routed away from high-voltage AC lines to minimize electromagnetic interference. Maintain a minimum bending radius for wire bundles to avoid mechanical stress on the header pins.
