Product Introduction
With a rated power of 15.6 W and a summable output current of 8 A, the Schneider 140CPS41400C power supply module from the Modicon Quantum series delivers reliable voltage regulation for industrial control systems. Designed to operate at an input voltage range of 48 to 60 V DC, it maintains stable power under varying conditions. Internal overvoltage and overload protections safeguard the module and connected equipment, extending service life and reducing maintenance costs.

The 13 ms hold-up time ensures that brief power dips do not interrupt critical processes, while the internal protections minimize the risk of damage, contributing to longer equipment life and lower total cost of ownership.
Application Scenarios
In manufacturing plants and process automation systems, the Schneider 140CPS41400C provides clean, regulated power to PLC racks, remote I/O stations, and control panels. Its summable output configuration allows flexible power distribution across multiple modules, reducing the need for additional power supplies. By maintaining stable voltage, it prevents erratic controller behavior and production stoppages, directly improving operational ROI.
Installation & Setup
Mount the 140CPS41400C in a standard Modicon Quantum rack. Ensure the DC input polarity is correct and use a 2 A time-lag fuse on the incoming supply as specified. The green LED (PWR OK) illuminates when the module is operating normally. For alarm wiring, connect the normally closed contact rated at 6 A/220 V to a monitoring system. Verify that the total output current does not exceed 8 A when summing multiple loads.
Maintenance & Reliability
Regularly inspect the 140CPS41400C for accumulated dust or debris, which can impair cooling. Verify the green LED status during routine walkthroughs. Ambient temperature should remain within the module's operating range to avoid thermal stress. These simple preventive actions extend the module's service life and help avoid unplanned downtime, reinforcing the cost benefit of choosing a robust power supply.
Selection Guide & Purchasing Advice
Before purchasing, confirm that your application's input voltage is within 48–60 V DC and that the total current draw does not exceed 8 A. The summable output allows adding loads, but plan distribution carefully.
