Output Design and Distribution

The Schneider TSXPSY5520M delivers two fully regulated DC outputs for the PLC system. A +5 VDC rail provides 5.0 Amps for all backplane logic and CPU circuits. The +24 VDC output delivers 0.8 Amps for connected field sensors and relays. Both outputs include independent overcurrent protection for safe operation.

Power Performance Characteristics

This supply maintains 78% typical efficiency across a wide load range. It holds up the +5 VDC output for 20 milliseconds after input power loss. Consequently, your CPU continues operating through most momentary line disturbances or sags. The unit draws a peak inrush current of only 20 Amps at 115 VAC.

Installation and Compatibility

Mount this power supply in the leftmost slot of any TSX Premium rack. The 5-pin terminal block accepts solid or stranded wires from 14 to 22 AWG. This module replaces earlier TSXPSY5520 and TSXPSY5520K units directly. You do not need any wiring changes or adapters for simple retrofits.

Energy Storage and Filtering

A 1000 µF primary capacitor stores enough energy for the hold-up time specification. This large capacitor also filters incoming AC line noise effectively. The supply requires no external batteries or additional energy storage devices. Therefore, you get a maintenance-free power solution for your Premium PLC system.

Thermal and Protection Features

The supply includes automatic overcurrent protection on both output rails. Short-circuit conditions will not damage the module or the backplane. An internal overtemperature sensor shuts down the unit if it exceeds 85°C. Two LEDs on the front panel indicate power-good status for each output rail.

Physical Design and Cooling

The toroidal transformer design reduces electromagnetic interference significantly. Passive convection cooling eliminates the need for any internal fans. The 0.85 kg unit provides stable mounting without stressing backplane connectors. Therefore, this supply suits silent operation environments like laboratories and control rooms.

Why Choose This Supply

System integrators prefer this power supply for its generous 5.0 Amp +5 VDC capacity. You can power large TSX Premium racks with many I/O modules comfortably. Therefore, this unit works perfectly for complex automation cells and process control skids.
