ABB 200-PSMG Power Supply Unit

This power supply unit provides DC power for ABB AC500 PLC systems. It converts 120 or 230V AC input to stable 24V DC output. Therefore, this component ensures reliable operation of connected I/O modules and controllers.

Physical Dimensions and Weight Specifications

The ABB 200-PSMG features a rugged metal housing for DIN rail mounting. Its width measures 65 mm for standard industrial enclosures. The total depth reaches 100 mm including the terminal block. Consequently, technicians can install this unit alongside other AC500 modules.

Interface Types and Connection Layout

The ABB 200-PSMG provides screw-clamp terminals for AC input wiring. Separate screw terminals deliver 24V DC output to the backplane. The front panel carries a green LED for output status indication. Hence, operators can verify power availability at a quick glance.

Component Count and Internal Architecture

This power supply contains one main board with a switching regulator circuit. The board holds two large electrolytic capacitors for output filtering. You will also find a bridge rectifier and a flyback transformer. An onboard fuse protects the unit from overcurrent events.

Energy Storage and Hold-Up Time

The ABB 200-PSMG stores energy in two 680µF output capacitors. This storage provides a 30 ms hold-up time after AC loss. Therefore, the PLC system continues operating during brief power interruptions. The unit requires no external battery for this function.

Protection Features and Operating Range

The power supply includes short-circuit and overvoltage protection. It also features overtemperature shutdown with automatic recovery. Users can operate this unit in temperatures from -10°C to 55°C. A built-in fan cools the internal components under heavy loads.
