140CPS21400C
Schneider Electric
Overview
The 140CPS21400C is a Power supply module in the Modicon Quantum automation platform range from Schneider Electric. It delivers stable control power at 5.1 V DC for Modicon Quantum racks.
Application & Technical Notes
As a power supply module, the 140CPS21400C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It conditions and distributes the low-voltage supply that powers the controller, I/O and communication modules on the same rack.
Key published characteristics include a 5.1 V DC rating, an operating temperature range of 0…60 °C. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (0…60 °C); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -40…185 °F (-40…85 °C). Avoid condensation — the rated humidity is 95 % without condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Ensure adequate ventilation and do not overload the supply beyond its published current budget; consider redundancy for critical racks. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the 140CPS21400C, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the output voltage and current to the Modicon Quantum load and allow headroom for future expansion. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications
The 140CPS21400C power supply module from Schneider Electric's Modicon Quantum series operates efficiently with an input voltage between 20 and 30 volts DC. It can handle an input current of 3800 mA and provides a stable output voltage of 5.1 volts DC for various applications.
Description
| Note | Schneider Electric's 140CPS21400C is a power supply module designed for reliable operation in various environments. It accepts an input voltage of 24 V DC, with a permitted range from 20 V to 30 V and consumes an input current of 3800 mA. The module exhibits a notable inrush current of 14 A when the input voltage is at 20 V and 25 A at 24 V, allowing for robust initial operation when powered on. Output stability is ensured, with the module supplying 5.1 V DC at a maximum output current capacity of 8 A, making it suitable for demanding applications. The design incorporates an associated fuse rating of 5 A and can handle an input power interruption of 100 milliseconds, or as brief as 1 millisecond at 20 V. Resistance to electromagnetic fields is adequate, rated at 10 V/m across frequencies from 80 to 2000 MHz, ensuring compatibility in environments with potential interference. The 140CPS21400C can function under ambient conditions with temperatures ranging from 0 to 60 °C and can be installed at altitudes of up to 5000 meters. Additionally, it withstands relative humidity levels of up to 95% without condensation. Electrostatic discharge resistance is rated at 4 kV, contributing to its reliability in industrial settings. At a net weight of 0.65 kg and dimensions of 16.3 cm high, 4.5 cm wide, and 31.2 cm long, this module is designed for ease of integration into control systems. This makes it an essential component for power management in Schneider Electric's Modicon Quantum installations. |
