Product Details

The Schneider 140CPS12400R redundant ac power supply module is a high-reliability power unit designed for Modicon Quantum PLC rack redundant control systems. This modicon quantum power module accepts 93~276V AC universal input with 47~63Hz frequency and converts AC power into stable 5.1V DC backplane power to supply CPU, communication and I/O modules on the rack. Two 140CPS12400R modules can work in parallel load-sharing mode. If one power unit fails, the remaining module will automatically take over full load without interrupting the whole control system, realizing non-stop power supply for critical automation equipment. It can provide 8A output current under redundant configuration. A green PWR OK LED indicator is arranged on the front panel, allowing technicians to quickly check power running status and fault information during on-site inspection. The module integrates built-in overvoltage, overload and short-circuit protection circuits to cut off output when abnormal current appears and prevent damage to expensive Quantum PLC modules. It adopts plug-in installation on Quantum backplane and supports hot swap for convenient maintenance. This is a spare replacement part for legacy automation systems, widely stocked for maintenance and renovation of power, petrochemical, metallurgy, water treatment and chemical projects requiring redundant power supply.
