Product Details

The Schneider 140CPS52400C conformal coated redundant dc power supply module is a high-reliability power unit designed for Modicon Quantum PLC racks working in moist, dusty and corrosive industrial environments. This modicon quantum power module accepts 100~150V DC input and converts it into stable 5.1V DC backplane power for 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, ensuring long-term stable operation in harsh plant environments. This power module supports parallel load-sharing redundant operation. When two identical 140CPS52400C modules work together, they share the rack load evenly. If one power supply fails, the remaining module will automatically take over the full load without interrupting PLC operation, guaranteeing continuous production process. It can deliver up to 8A output current under redundant configuration. A green PWR OK LED indicator on the front panel shows real-time module operating state, allowing technicians to quickly check power health and diagnose power faults on site. Built-in overvoltage, overload and short-circuit protection circuits cut off output automatically under abnormal electrical conditions to protect expensive Quantum PLC modules. It supports direct plug-in installation on Quantum backplane and hot swap for convenient maintenance. This original product was discontinued on Dec 31,2022, 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 railway projects to provide redundant stable backplane power supply for Modicon Quantum PLC control racks with 100~150V DC power input under harsh industrial conditions.
