140CPS41400C Schneider Power Supply Module Quantum

Schneider 140CPS41400C 5.1V DC Power Supply

The 140CPS41400C power supply module forms the backbone of reliable system operation within the Modicon Quantum series. Manufactured by Schneider Electric, this unit converts incoming DC voltage into a stable, low-voltage output that feeds the backplane and connected I/O modules. Its robust design makes it a trusted choice for continuous-duty environments like manufacturing lines, water treatment plants, and energy management systems.

This module accepts a wide input range from 48 to 60 V DC, accommodating typical industrial battery and rectifier sources. It delivers a regulated 5.1 V DC output with a summable current capacity of 8 A, which means you can distribute power flexibly across multiple modules in the rack. The 140CPS41400C includes both overvoltage and overload protection internally, so connected equipment stays safe from unexpected supply faults.

Technical Specifications

The 140CPS41400C draws a maximum input current of 3.8 A under full load, while its inrush current reaches 14 A at 40 V for a brief moment during startup. To handle these surges, the unit employs a 2 A time-lag fuse that tolerates temporary spikes without nuisance tripping. Input hold-up time measures 13 ms at 48 V, giving the system enough cushion to ride through short power interruptions without resetting.

On the output side, the module provides 5.1 V DC at 8 A in a summable configuration. This feature lets you combine current from multiple power supplies if your rack demands higher total capacity. The alarm output is a normally closed (NC) contact rated for 6 A at 220 V, which you can wire to a central monitoring panel or PLC input for remote fault indication. Additionally, a green LED labeled "PWR OK" gives a clear visual status at a glance.

Mechanical and Environmental Parameters

Weighing approximately 0.5 kg net, the 140CPS41400C occupies a standard Quantum rack slot and requires no special mounting hardware. Its compact standard format ensures seamless integration with existing chassis. The unit operates reliably between 0°C and 60°C, with storage capability from -25°C to 85°C. Humidity tolerance reaches 95% non-condensing, making it suitable for both climate-controlled control rooms and harsher field locations.

Installation and Wiring Guidance

Installing the 140CPS41400C is a quick process. Begin by sliding the module into an empty slot on the Quantum backplane, ensuring firm seating against the connectors. Secure it with the retaining screws to prevent vibration loosening. Next, connect the DC input wiring to the designated terminals, observing correct polarity—reverse connection may damage internal components. Use appropriately rated cables for the 3.8 A input current to minimize voltage drop.

For the alarm output, wire the NC contact to your monitoring circuit. Remember that this contact switches 6 A at 220 V, so use suitable relay or PLC input modules. After wiring, apply input power and check that the green LED illuminates. If the LED stays off, verify input voltage and fuse condition before troubleshooting further.

Packaging and Shipping

Each 140CPS41400C ships in a protective anti-static bag with a printed installation guide. The package does not include mounting screws, cables, or configuration software. We dispatch all orders via FedEx, UPS, or DHL, with tracking numbers provided upon shipment. The module is securely cushioned to withstand normal transit vibrations and impacts.

Frequently Asked Questions (FAQ)

Q1: Can the 140CPS41400C operate with a 24V DC input?
A: No. This module requires 48–60 V DC input. Using lower voltage will not start the unit or may cause erratic behavior.

Q2: What does "summable" output mean for the 140CPS41400C?
A: It means you can parallel the outputs of multiple power supplies to increase total current capacity, as long as each unit shares the load properly.

Q3: How do I reset the module after an overvoltage trip?
A: The protection is self-recovering. Remove input power, wait 10 seconds, then reapply. If the fault persists, check your external wiring.

Q4: Is the alarm output active during normal operation?
A: The NC contact remains closed when power is good. It opens only when the output falls outside specification or the module experiences a fault.

Q5: What happens if the internal fuse blows?
A: The fuse is not user-replaceable. Contact Schneider Electric service for repair or replacement of the 140CPS41400C unit.
