Schneider ASPRTU258C Power Supply

The Schneider ASPRTU258C provides stable DC power to Modicon PLC racks and field devices. You can install this module into the dedicated power slot of any Modicon base. It converts 115 V AC or 230 V AC into regulated 24 V DC and 5 V DC outputs. This unit supports CPUs, I/O modules, and communication cards reliably.

Technical Specifications and Hardware Configuration

The Schneider ASPRTU258C measures 128 mm in height. Its width reaches 56 mm, and the depth equals 135 mm. The Schneider ASPRTU258C weighs approximately 0.72 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains three electrolytic capacitors for bulk energy storage. These capacitors provide 25 milliseconds of hold-up time during input dips. One 4-pin screw terminal block accepts AC input wiring. A dedicated 8-pin connector delivers DC outputs to the backplane.

Electrical Ratings and Performance Characteristics

The Schneider ASPRTU258C accepts input voltages from 85 V AC to 264 V AC. It operates at line frequencies of 47 Hz to 63 Hz automatically. This module delivers 5 V DC at 8 A for the backplane logic. It also provides 24 V DC at 2 A for output modules and relays. Output ripple stays below 35 mV peak-to-peak at full load. Efficiency reaches 84 percent under typical operating conditions. Consequently, this unit powers complete Modicon configurations effectively. Overvoltage protection clamps both outputs at safe levels. Short-circuit protection shuts down individual outputs during wiring faults.

Installation and Operational Guidelines

You must slide the Schneider ASPRTU258C into the leftmost slot of the Modicon rack. Transitioning to wiring, use 1.5 mm² stranded wire for the AC terminals. A green front LED indicates normal output voltage presence. The module requires 40 mm of free space above and below for airflow. For safety, disconnect mains power before removing the unit. The operating temperature range sits between 0°C and 60°C reliably.
