140CPS11420
Schneider Electric
Overview
The 140CPS11420 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 140CPS11420 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 32…140 °F (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 (32…140 °F (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 140CPS11420, 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.
