Product Overview
Downtime on a control panel rarely waits for a convenient moment. When a Modicon Quantum rack loses its power supply, the whole line can stall. The Schneider Electric 140CPS11400 is the module that keeps that rack alive: a DIN rail mounted power supply delivering a rated 8A at a 24 V DC output.
This is a practical, panel-ready unit. It accepts 115/230 VAC input at 50/60 Hz, so it fits standard electrical setups across plants and skids. Built-in short circuit, overload and overvoltage protection guard both the module and the devices downstream. Certifications include UL, CE and CSA, and the IP20 rating confirms it is intended for indoor cabinet use.

What the Key Ratings Mean in Practice
The 8A rating is the headline figure for most buyers. It sets how much 24 V DC load the module can carry, so it directly limits how many I/O modules and field devices you can hang off one supply. If your rack has grown since commissioning, verify the total current draw before you assume a like-for-like swap is enough.
The 115/230 VAC input range means the same module suits low-voltage and higher-voltage panel feeds. Combined with 50/60 Hz operation, that flexibility simplifies spares planning across sites with different supply standards.
Natural convection cooling matters in sealed enclosures. With no fan, there is no moving part to fail and no airflow path to filter. The trade-off is that heat must escape through the cabinet itself, so keep the 0°C to 60°C operating window and the 80% RH non-condensing limit in mind when you plan panel layout.

Where This Module Fits
The 140CPS11400 suits Modicon Quantum control systems in oil and gas, water treatment, and general process automation. Typical duties include powering I/O racks on compressor stations, feeding control panels on pipeline skids, and supporting legacy Quantum installations that still run critical plant functions.
Because the unit is DIN rail mounted and weighs 1.63 lbs (0.74 kg), it drops into standard enclosures without special hardware. That keeps replacement work short when a supply fails mid-shift.
Buyer’s Checklist Before You Order
Confirm four things: the rack is a Modicon Quantum system, your load stays within the 8A rated current, your panel feed matches 115/230 VAC at 50/60 Hz, and the enclosure stays within 0°C to 60°C at up to 80% RH without condensation. Also check that the mounting rail and cabinet space suit the module footprint.
