Power Stability Starts Here
Downtime in a Modicon Quantum rack often traces back to one weak link: the power supply. The Schneider Electric 140CPS41400C ends that problem. This Modicon Quantum power supply module converts a 48–60 V DC input into a steady 5.1 V DC output, keeping your control system alive when other supplies sag under load.

What the 140CPS41400C Delivers
Regulated Output That Holds
The module supplies 5.1 V DC at up to 8 A in a summable configuration. That means you can distribute power across multiple loads without adding a second supply. Rated power sits at 15.6 W, and input current stays at or below 3.8 A.
Built-In Protection, Not Add-Ons
Overvoltage and overload protection are internal. A 2 A time-lag fuse handles surges without nuisance trips. Inrush current reaches 14 A at 40 V, and input hold-up time is 13 ms at 48 V — enough to ride through brief interruptions.
Signaling You Can Trust
A green LED (PWR OK) confirms power status at a glance. One normally closed alarm output rated 6 A at 220 V lets you wire a fault signal directly to your control system.
Where It Fits
Oil and Gas Control Rooms
Remote sites run on DC power. The 48–60 V DC input range matches common battery and rectifier systems, so the 140CPS41400C drops into existing panels without a converter.
Industrial Automation Racks
Quantum racks need clean 5.1 V DC logic power. The summable output feeds multiple modules from one slot, simplifying panel layout and reducing spare-part count.
Upgrades and Replacements
When an aging supply drifts or fails, the standard format of this unit speeds replacement. Keep a spare on the shelf — fast dispatch, worldwide.

Installation and Setup
Mount the module in a standard Quantum slot. Verify input polarity before energizing. Confirm the 2 A time-lag fuse rating matches your circuit protection. After power-up, check the PWR OK LED and test the alarm contact. For technical selection help, contact Oil AutoTech.
Maintenance and Reliability
Inspect the module periodically for loose connections and dust buildup. Internal overvoltage and overload protection reduce component stress, extending service life. Keep spare fuses on hand and log LED behavior during routine checks.
