Product Description
The Schneider Electric 140CPS12420 is a high-capacity DC power supply module engineered for the Modicon Quantum PLC platform. It delivers regulated 5 VDC power to Quantum backplanes, ensuring consistent operation of CPUs, I/O modules, and communication devices.
Designed for installations with DC power distribution, the 140CPS12420 is ideal for large industrial racks in heavy process industries, offshore platforms, substations, and infrastructure projects. It provides robust protection against overvoltage, overload, short-circuits, and thermal issues while incorporating diagnostic LEDs for rapid status monitoring.
This module supports both standalone and redundant configurations, supplying up to 20 A of output current—higher than earlier Quantum DC modules—making it suitable for high-demand environments. With standard backplane mounting, it integrates seamlessly with 10-slot or 16-slot Quantum racks.
