Product Details
Product Overview
The 140CPS21400 provides regulated DC power to the Modicon Quantum backplane and attached I/O modules. This summable power supply module converts a 24V DC input into a stable 5.1V DC bus voltage. Its "summable" architecture allows users to install multiple units in the same rack to satisfy high-current demands or to establish a redundant power configuration. We supply this unit as 100% Brand New and Original, ensuring full compliance with factory performance specifications and industrial safety standards.

Engineering Advantages
-
Summable Redundancy: This module supports load-sharing. By installing two 140CPS21400 units, you create a redundant power system that prevents total controller failure if one power source or module fails.
-
Superior Power Ride-Through: The unit manages power interruptions up to 100 ms. This capability prevents nuisance CPU resets during momentary voltage dips or industrial grid switching, maintaining process continuity in unstable power environments.
-
Hazardous Location Reliability: With FM Class 1 Division 2 certification, this power supply operates safely in explosive atmospheres. It withstands electromagnetic fields up to 10 V/m, ensuring stable DC output even when placed near high-frequency interference sources.
-
Integrated Fault Monitoring: A dry contact alarm output (1 NC) provides immediate feedback to external monitoring systems. The "PWR OK" green LED allows maintenance personnel to verify module health at a glance, significantly reducing troubleshooting time.
-
High Altitude Performance: The internal design supports operation at altitudes up to 5000 meters (over 16,000 ft), making it suitable for specialized applications in mining and aerospace testing facilities.
FAQs
-
What does "summable" mean for the 140CPS21400?
"Summable" means you can parallel this module with another 140CPS21400 on the same backplane to increase the total available current to 16A or to provide redundant power backup for critical applications.
-
Does this unit require a specific fuse for protection?
Yes. Schneider Electric recommends an external 5 A slow-blow fuse on the input line to protect the module and wiring from overcurrent conditions.
-
Can I replace an existing 140CPS21100 with this 140CPS21400?
Yes, the 140CPS21400 provides a higher output current (8A) compared to the 3A provided by the 140CPS21100, effectively serving as a high-capacity upgrade for the same 24V DC input range.
-
Is this a refurbished unit?
No. We guarantee this is a 100% Brand New original Schneider Electric product. It comes in factory-original packaging with all manufacturer quality seals intact.
