Schneider 140CPS41400C Power Supply Module for Modicon Quantum PLCs

The Schneider 140CPS41400C provides stable DC power to Modicon Quantum PLC racks. You can install this module into the dedicated power slot of any Quantum base. It converts 24 V DC input into regulated 5 V DC output for the backplane. This unit supports CPUs, I/O modules, and communication cards reliably.

Technical Specifications and Hardware Configuration

The Schneider 140CPS41400C measures 138 mm in height. Its width reaches 54 mm, and the depth equals 145 mm. The Schneider 140CPS41400C weighs approximately 0.58 kilograms. A single internal PCB carries all regulation and isolation circuits. The module contains two electrolytic capacitors for basic energy storage. These capacitors provide 10 milliseconds of hold-up time during input dips. One 3-pin screw terminal block accepts 24 V DC input wiring. A dedicated 10-pin connector delivers 5 V DC output to the backplane.

Electrical Ratings and Performance Characteristics

The Schneider 140CPS41400C accepts input voltages from 18 V DC to 30 V DC. It delivers a nominal output of 5 V DC at 14 A continuously. Output ripple stays below 25 mV peak-to-peak at full load. Efficiency reaches 88 percent under typical operating conditions. Consequently, this unit powers demanding Quantum configurations effectively. Overvoltage protection clamps the output at 5.5 V DC maximum. Reverse polarity protection prevents damage from incorrect input wiring. Short-circuit protection shuts down the output during overload conditions.

Installation and Operational Guidelines

You must slide the Schneider 140CPS41400C into the leftmost slot of the Quantum rack. Transitioning to wiring, use 1.5 mm² stranded wire for the DC input 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 input power before removing the unit. The operating temperature range sits between 0°C and 60°C reliably.
