Product Details

The Schneider 140CPS41400C conformal coated summable 48V dc power supply module is a high-reliability power unit designed for Modicon Quantum PLC racks operating in dusty, moist and corrosive industrial environments. This modicon quantum power module accepts 48~60V DC input and converts it into stable 5.1V DC backplane power to supply CPU, communication and I/O modules installed on the rack backplane. The PCB circuit board adopts conformal coating treatment, which protects internal electronic components from moisture, dust and corrosive gas, maintaining stable operation in harsh chemical, petrochemical and factory environments. This summable power supply supports parallel connection of multiple identical modules to expand total rack power capacity, delivering up to 8A output current. A green PWR OK LED indicator and one NC 6A@220V fault alarm relay contact are equipped on the front panel. The relay can output power failure alarm signals to external control system, while the LED allows technicians to quickly check module operating status and diagnose power faults during routine site inspection. Built-in overvoltage, overload and short-circuit protection circuits can automatically cut off output under abnormal electrical conditions to protect expensive Quantum PLC modules from damage. It supports direct plug-in installation on Quantum backplane and hot swap for convenient maintenance. This original product has been discontinued, widely stocked as spare parts for maintenance and renovation of legacy industrial automation systems. It is widely used in power, petrochemical, metallurgy, water treatment and chemical projects to provide stable backplane power supply for large Modicon Quantum PLC racks with 48~60V DC input under harsh industrial conditions.
