Technical Specifications

• Model: 405A528G62

• Manufacturer: Westinghouse / Emerson

• Compatible Systems: Ovation, WDPF DCS

• Type: Chassis‑mounted, plug‑in DC power supply

• Input: 115/230 VAC, 50/60 Hz (auto‑sensing)

• Output: Multiple regulated DC rails (Multibus standard voltages), higher current rating than G61

• Hot‑swap: Yes (replace online without system shutdown)

• Redundancy: Supports 1+1 redundant operation

• Dimensions (H×W×D): ~13.3 cm × 44.5 cm × 25.4 cm

• Weight: ~1.42 kg

• Operating Temperature: 0 °C to 50 °C

• Relative Humidity: 5%–95%, non‑condensing

• Protection: Overvoltage, overcurrent, short‑circuit, overtemperature

• Features: EMI filtering, conformal coating, LED status indicators

Key Difference: G61 vs G62

• 405A528G61: Standard‑output power supply

• 405A528G62: Upgraded, higher‑current version; same form/fit/function, higher power capacity for heavier I/O loads

Application Fields

• Power Generation: Thermal, nuclear plants (Ovation/WDPF DCS core power)

• Process Industries: Petrochemical, pulp & paper, cement, water treatment

• High‑Load Chassis: Preferred for chassis with full I/O and redundant DPUs

• Legacy System Maintenance: Direct replacement for aging G61 or failed supplies

Installation & Operation

1. Insert into dedicated power slot of 405A528 series chassis.

2. Secure front‑panel screws; connect AC input to chassis.

3. Verify Power OK LED (green = normal).

4. For redundancy, install a second G62 in the adjacent slot.

5. Hot‑swap faulty units during operation if Fault LED (red) illuminates.

Diagnosis & Maintenance

• Green Power LED: Normal DC output.

• Red Fault LED: Overvoltage, overcurrent, overtemperature, or fan failure.

• Quarterly: Inspect LEDs, connectors, and vents; clean dust if needed.

• Safety: Disconnect AC before removal; allow capacitors to discharge.
