MeloAuto-Trusted PLC & DCS Parts Supplier
The Schneider 140CPS21100C 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 115 V AC or 230 V AC into regulated 5 V DC and 24 V DC outputs. This unit supports CPUs, I/O modules, and communication cards reliably.
Technical Specifications and Hardware Configuration
The Schneider 140CPS21100C measures 138 mm in height. Its width reaches 54 mm, and the depth equals 145 mm. The Schneider 140CPS21100C weighs approximately 0.65 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains four electrolytic capacitors for bulk energy storage. These capacitors provide 30 milliseconds of hold-up time during input dips. One 3-pin screw terminal block accepts AC input wiring. A dedicated 10-pin connector delivers DC outputs to the backplane.

Electrical Ratings and Performance Characteristics
The Schneider 140CPS21100C 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 12 A for the backplane logic. It also provides 24 V DC at 3 A for output modules and relays. Output ripple stays below 30 mV peak-to-peak at full load. Efficiency reaches 85 percent under typical operating conditions. Consequently, this unit powers demanding Quantum configurations reliably. 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 140CPS21100C into the leftmost slot of the Quantum 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.
