Schneider TSXPSY5520MC Power Supply Module

Technical Overview of This Rack Power Source

The Schneider TSXPSY5520MC provides clean DC power to your PLC rack. This power supply module belongs to the Modicon Premium TSX series from Schneider Electric. It converts AC mains into regulated voltages for backplane operation. Consequently, all connected I/O and CPU modules receive stable power.

Hardware Specifications and Design Details

This power supply module weighs approximately 0.9 kg. Its compact dimensions are 130 mm in height, 80 mm in width, and 160 mm in depth. The Schneider TSXPSY5520MC features a single screw terminal block for AC input. It supplies 5 V DC and 24 V DC to the backplane bus. The module contains one internal transformer and multiple filtering capacitors. It stores limited energy in its output capacitors for short hold-up time. Therefore, the module maintains output for approximately 15 milliseconds during power interruptions.
