140CPS21100 Modicon Quantum Power Supply Module | Schneider Electric

Product Overview

The Schneider Electric 140CPS21100 serves as a high-efficiency standalone power supply module for the Modicon Quantum automation platform. This module converts a nominal 24V DC input into a regulated 5.1V DC output to energize the Quantum backplane and attached I/O modules. Designed for high-availability industrial environments, it provides consistent power delivery even during momentary voltage fluctuations. We supply this module as 100% brand new original equipment, ensuring full compliance with factory specifications and maximum system reliability for your PLC infrastructure.

Engineering Advantages

• Optimized for Battery-Backed Systems: The 24V DC input range specifically targets industrial environments utilizing battery-backed power systems. This allows the 140CPS21100 to maintain stable rack operation during primary AC failures without additional DC-to-AC conversion.

• Resilience Against Power Microbreaks: This module handles power interruptions up to 20 ms (at 25V). This capability prevents nuisance PLC resets caused by electrical noise or large motor starts on the same power bus, maintaining process continuity in high-vibration or electrically noisy facilities.

• Hazardous Location Readiness: With FM Class 1 Division 2 certification, the 140CPS21100 operates safely in environments where flammable gases or vapors may exist. This makes it a standard choice for oil and gas upstream applications and chemical processing plants.

• Robust Electromagnetic Shielding: The hardware resists electromagnetic fields up to 10 V/m and electrostatic discharges up to 8 kV (air). These protections ensure the power supply does not propagate electrical noise to the sensitive logic modules sharing the backplane.

• High-Altitude Performance: Unlike standard commercial power units, the 140CPS21100 maintains its dielectric and thermal ratings at altitudes up to 5000 meters. This allows for reliable deployment in high-altitude mining and energy operations.

FAQs

• What is the difference between "Standalone" and "Redundant" power supplies?

  The 140CPS21100 is a standalone module. It powers the rack independently. If your application requires high availability, you should look for the redundant versions (like 140CPS21400) which allow two power supplies to share the load on the same rack.

• Does this module require an external fuse?

  While the module includes internal protection, Schneider recommends an external 2.5 A slow-blow fuse on the 24V DC input line to protect the wiring and power source from internal hardware faults.

• How do I verify the module's health without a laptop?

  The front panel features a "PWR OK" green LED. If the output voltage remains within the safe 5.1V DC window, this LED stays lit. If the LED turns off, check for an input voltage dip below 20V or an output overload.

• Is this a refurbished or "surplus" unit?

  No. We guarantee this 140CPS21100 is 100% Brand New original factory stock. It arrives in the original Schneider Electric PCE package with a matching GTIN 3595861135222.
