Schneider 140CPS11420 Power Supply Module

Description

The Schneider 140CPS11420 is a power supply module designed for the Modicon Quantum series programmable logic controller (PLC) platform, engineered to deliver stable power for industrial automation systems. It features a standard modular form factor, weighs 0.65 kg, and supports both stackable and standalone configurations to match varying power demands. Key protective features include internal output overvoltage and overload protection, plus a 5A normally closed relay contact for triggering input power loss signals; the relay de-energizes when input voltage drops below 70V AC for 115V AC settings or 140V AC for 230V AC settings. Technical specifications include a wide 115V/230V AC input voltage range with 47-63Hz input frequency, and input voltage total harmonic distortion of less than 10% of the fundamental RMS value. It provides a 5.1V DC output to the bus, with a maximum output current of 11A in standalone configuration and 20A in summable configuration. The module has a power rating of approximately 130VA, with internal power consumption below 12W at full load, and can withstand 1/2 cycle input power interruptions of no less than 1 second under full load, minimum rated line voltage, and frequency. Operating temperature ranges from -10 degrees Celsius to 60 degrees Celsius. A related model, 140CPS11420C, is a high-performance redundant variant with 85-264V AC/18-32V DC wide input, automatic switchover (interruption time <10ms) on main power failure, support for up to 4 parallel units for 20A total output, conversion efficiency ≥90%, and voltage accuracy ±0.5% at full load. Both models are ideal for discrete manufacturing, process industries, power utilities, and building automation systems.
