Basic Information

• Manufacturer: Westinghouse (now Emerson Automation Solutions)

• Origin: USA

• Function: Central power supply for WDPF DCS cabinets; provides regulated DC power to multibus backplane, I/O modules, and controller cards.

• Compatible Chassis: 1660D07G01 CAMAC Crate

• Mounting: 19” rack-mount, slide-in unit

• Status: Legacy, in stock (new / remanufactured / repair available)

• Key Difference: G05 is the final upgraded 230VAC version (enhanced components, improved reliability, longer MTBF); G01/G02/G04 are older 230VAC revisions; G03 is 115VAC.

Specifications

• Input Voltage: 230 VAC, 50/60 Hz (fixed, not switchable)

• Output Voltages: +5 VDC, ±12 VDC, +24 VDC (multibus standard)

• Power Rating: ~400 W

• Cooling: Internal fan cooled (improved fan design vs G01–G04)

• Operating Temp: 0–50°C

• Humidity: 5–95% RH, non-condensing

• Weight: ~18.7 lbs (8.5 kg)

• Dimensions: 16.00 × 5.00 × 12.00 in (approx.)

Key Features

• Multibus compatible: Designed for WDPF multibus architecture, stable power distribution.

• Integrated protection: Over-voltage, over-current, short-circuit protection (enhanced sensing circuits).

• Hot-swap capable: Can be replaced without shutting down the system.

• Status indicators: Front-panel LEDs for AC input, DC outputs, and fault alarm (brighter, longer-life LEDs).

• Robust construction: Heavy-duty metal enclosure for industrial 24/7 operation.

• 230VAC optimized: For European/Asian 230VAC grids; do not use on 115VAC without step-up transformer.

• Upgraded reliability: Improved capacitors, rectifiers, and fan motor; longer mean time between failures (MTBF).

Application Fields

• Power Generation: Fossil power plants, combined-cycle plants (WDPF DCS, 230VAC sites).

• Process Industries: Petrochemical, refining, gas processing (Europe, Asia, LATAM).

• Heavy Industry: Pulp & paper, metallurgy, water treatment.

• Legacy System Maintenance: Spare power supply for existing WDPF 230VAC installations; preferred replacement for G01/G02/G04 due to upgraded components.
