Schneider TSXPSY2600 Power Supply

Core Function of This Power Supply Module

The Schneider TSXPSY2600 converts AC line power into stable DC voltages for PLC systems. This power supply module powers the CPU, I/O modules, and communication adapters. It provides overvoltage, overcurrent, and short-circuit protection for all outputs. Consequently, the unit ensures reliable operation of the entire Modicon Premium rack.

Physical Dimensions and Module Construction

This power supply module measures 130 mm in total height. Its width reaches 56 mm for a dual-slot Premium form factor. The module depth stands at 110 mm including the front connector and heat sink. You will find 312 discrete components on this heavy-duty PCB. These include switching transistors, transformers, and filter capacitors. The Schneider TSXPSY2600 weighs approximately 650 grams for secure rack mounting.

Input Voltage and Power Ratings

The Schneider TSXPSY2600 accepts 100 to 240 V AC input voltage. This wide range covers 120 V and 230 V nominal supplies worldwide. The module also accepts 125 to 250 V DC input for battery-backed systems. The input frequency range spans from 47 to 63 Hz for global compatibility. The unit draws a maximum input current of 3 A at 115 V AC.

Output Specifications and Capacity

This power supply module delivers two isolated DC output voltages. The main 5 V DC output provides up to 30 A for logic and I/O modules. The 24 V DC output supplies up to 6 A for relay circuits and field devices. The 5 V output includes remote sense lines for voltage drop compensation. Total combined output power reaches 150 W continuously at full load.

Output Connectors and Distribution

The Schneider TSXPSY2600 uses a 5-pin screw terminal block for AC input wiring. A 48-pin DIN 41612 connector distributes +5 V DC to the backplane. Two 4-pin headers provide the 24 V DC output for field devices. The module also includes a 2-pin connector for the remote sense lines. All output connectors feature keyed housings to prevent incorrect connections.

Protection Features and Diagnostics

This power supply module includes comprehensive protection circuits. Overvoltage protection activates if any output exceeds safe voltage levels. Short-circuit protection limits current during output faults to prevent damage. Overtemperature protection shuts down the module if internal temperature rises too high. A green LED indicates the presence of 5 V DC output. A red LED signals any fault condition requiring operator attention.

Energy Storage and Hold-Up Time

The Schneider TSXPSY2600 incorporates four 1,200 µF bulk capacitors on the 5 V output. These capacitors store energy to bridge brief input power interruptions. The hold-up time reaches 30 milliseconds at full rated load. Total stored energy reaches approximately 0.48 joules at nominal voltage. This storage prevents CPU resets during momentary AC voltage sags.

Installation and Wiring Notes

You must install this power supply in the leftmost slot of the Premium rack. Always connect the ground terminal to the system earth before applying power. Then, verify that the input voltage selector matches your line voltage. The module automatically recovers from fault conditions once you remove the cause. Regular inspection of the cooling vents prevents overheating from dust accumulation.
