H2: Product Overview

The WESDAC D20 PS is an industrial-grade power supply module manufactured for the GE WESDAC D20 distributed remote terminal unit (RTU) and substation automation platform. It delivers regulated, clean 24VDC power to D20 controllers, I/O modules, communication boards and field termination hardware, widely deployed in power generation, utility substations, and GE Speedtronic Mark V / Mark VI turbine control systems.

Built for continuous 24/7 operation in harsh industrial environments, the WESDAC D20 PS converts universal AC input into stable DC power for mission-critical automation equipment. Its rugged construction, full protection circuits and redundancy capability help reduce unexpected downtime for power and energy infrastructure projects.

System integrators, maintenance engineers and plant operators select the GE WESDAC D20 PS as a trusted replacement or spare power module for legacy WESDAC D20 RTU systems. We supply new, tested surplus WESDAC D20 PS units with full inspection before shipment.

H2: Key Features of WESDAC D20 PS

• Universal wide AC input: 85VAC to 264VAC, 47–63Hz, global mains compatibility
• Regulated 24VDC output (adjustable 22VDC–26VDC), maximum 10A continuous / 240W power
• N+1 redundancy support via parallel connection with diode OR-ing design
• Built-in protection: overvoltage, overcurrent, short-circuit and thermal shutdown
• High efficiency >88% under full load, lower heat generation for cabinet installation
• Supports forced air cooling or convection cooling (derated operation)
• Compact rack-mount design, direct fit into standard WESDAC D20 chassis
• Industrial temperature rating for substation and power plant cabinet environments
• Fully tested before delivery, suitable for direct drop-in replacement of original units
