GE 8920-PS-DC-02 DC Power Supply Module

GE 8920-PS-DC-02 is a rack-mounted DC power supply module designed for GE industrial control systems. It converts the input DC power into stable regulated output voltage, supplying reliable power for controller boards and I/O modules in the control rack.

This module comes with built-in overvoltage, overcurrent and short-circuit protection circuits. It has status LED indicators on the front panel and supports hot swap replacement. It is widely used as spare parts for GE industrial control cabinets in power, oil & gas and metallurgy industries.
