Product Details:

Schneider 140CPS11420 is a rack-mounted AC power supply module for Modicon Quantum PLC automation systems. This unit can work as standalone or summable power source, accepting 93-132V AC / 170-276V AC input at 47~63Hz and converting AC power into stable 5.1V DC internal bus power to feed CPU, I/O and communication modules on the Quantum backplane. It delivers 130 VA rated power output and supports parallel installation for redundant power configuration to improve system availability. The 140CPS11420 integrates overcurrent, short-circuit and overvoltage protection circuits to guard the whole PLC rack against power anomalies. Built-in self-diagnostic functions monitor internal module status and power faults, providing status indication for maintenance staff to quickly identify power failures. Industrial-grade hardware design features strong vibration and electromagnetic interference resistance, suitable for long-term continuous operation in power plants, petrochemical plants and manufacturing workshops. Installed in standard Quantum rack slots, this power module connects reliably with backplane to supply power for all rack modules. Widely applied in process automation industries, this power unit is essential hardware for Modicon Quantum control systems. It maintains stable power supply for the PLC station, reduces unexpected shutdown risks caused by power failure and guarantees safe and continuous production operation.
