Product Details

140CPS11420 is summable‑type AC power supply for Schneider Modicon Quantum PLC racks,supplies stable 5.1VDC bus power for CPU,I/O and communication modules.

It supports 115/230VAC wide‑range mains input. Standalone mode delivers 11A; two units parallel summable up to 20A,supports N+1 redundant power configuration for medium‑large racks with many modules. Equipped with NC alarm relay contact for external power failure signal output; front panel has PWR‑OK and battery‑low indicator LED,also reserved lithium battery socket for CPU memory retention.

Built‑in overvoltage,overload and short‑circuit protection improves system reliability. Note:140CPS11420C is conformal‑coated version for corrosive harsh environment. This model is discontinued,widely used as replacement spare‑part for legacy Quantum automation systems.
