The Schneider Electric 140CPS12420 Modicon Quantum PLC Power Supply Module delivers regulated 5 V DC power to Quantum PLC components and is designed for rack-mounted integration on the Modicon Quantum backplane. Operating from 115/230 V AC input, it provides 8 A at 5 V DC (approximately 40 W) and includes overload, overvoltage, and short‑circuit protection, with redundancy support in a redundant configuration. It supports a wide operating range of 0°C to +60°C, storage from -40°C to +85°C, and IP20 protection, with compliance to CE, UL, and CSA standards. Common replacements include 140CPS21400 and BMXCPS2010, and this unit is used in industrial automation, PLC racks, and process control systems requiring stable power distribution for Quantum PLC systems.
