The 140CPS52400C from Schneider Electric provides reliable DC power for Modicon Quantum automation platforms. This module accepts a nominal input of 125V DC, with an acceptable range from 100V to 150V DC. Consequently, it adapts well to varying battery or rectifier outputs common in industrial settings. The unit delivers a stable 5.1V DC output at 8A, sufficient to power multiple I/O modules and controllers. Moreover, the 140CPS52400C features redundant power supply capability, enhancing system availability for critical processes. Its internal protections against overload and overvoltage conditions safeguard connected equipment from electrical faults.
The 140CPS52400C draws only 0.5A input current at 125V, demonstrating excellent efficiency. Its inrush current reaches 28A at 125V, which is typical for capacitor charging during startup. The output voltage remains regulated at 5.1V DC, ensuring consistent power for the backplane. Furthermore, the output current rating of 8A supports substantial system expansion. The hold-up time is ≤1 ms, maintaining output stability during brief power interruptions.
Additionally, the module's power dissipation is calculated as 6 + (1.5 × Iout) watts, where Iout is the output current in amperes. For example, at full 8A load, dissipation reaches 18W. This predictable thermal behavior aids in cabinet cooling design. A 2A slow-blow fuse provides supplementary protection against sustained overcurrent events.
The 140CPS52400C incorporates comprehensive internal protection mechanisms. Overvoltage protection prevents output voltage from exceeding safe limits, shielding sensitive electronics. Overload protection limits output current during short-circuit conditions, preventing damage to the power supply itself. These features operate automatically without user intervention.
Moreover, this module supports redundant configurations. You can install two 140CPS52400C units in parallel for critical applications. If one module fails, the other continues supplying power seamlessly. This redundancy ensures uninterrupted operation in mission-critical processes like chemical plants or power generation facilities.
The 140CPS52400C operates reliably across a wide temperature range. It functions from 0°C to 60°C ambient, suitable for most control rooms and cabinets. Storage temperatures span -40°C to 85°C, accommodating warehouse conditions. Relative humidity tolerance reaches 95% without condensation, protecting against moisture damage.
A conformal coating (Humiseal 1A33) protects the PCB from dust, humidity, and chemical contaminants. The module carries UL 508, CSA C22.2 No 142, and FM Class 1 Division 2 certifications. These approvals confirm its suitability for hazardous locations. Additionally, electrostatic discharge immunity meets 4 kV contact and 8 kV air discharge per IEC 801-2. Electromagnetic field resistance is rated at 9.1 V/m (10 V/m) from 80 to 2000 MHz per IEC 801-3. The module weighs 0.65 kg, simplifying installation and handling.
Installing the 140CPS52400C follows standard Quantum rack procedures. First, ensure the system is powered off before insertion. Align the module with the designated power supply slot, typically on the left side of the rack. Push firmly until the retaining clips engage securely. Then, connect the DC input wiring to the terminal block, observing correct polarity.
For redundant configurations, install two 140CPS52400C modules in adjacent slots. Wire both inputs to the same DC source or separate sources for higher availability. Additionally, verify that the total backplane current does not exceed 8A. Use the PWR OK green LED to confirm proper operation after power-up.

Q1: Can the 140CPS52400C operate with 24V DC input?
A1: No, this module requires 125V DC nominal input (100–150V range). It does not accept 24V DC.
Q2: Is the 140CPS52400C hot-swappable?
A2: This module is not designed for hot-swapping. Always power down the rack before insertion or removal.
Q3: How do I connect two 140CPS52400C modules for redundancy?
A3: Install both modules in the rack and wire their DC inputs to the same or separate sources. The backplane automatically handles load sharing.
Q4: What does the green PWR OK LED indicate?
A4: The green LED illuminates when the output voltage is within specification. If it is off, check the input supply and fuses.
Q5: Does the 140CPS52400C include a replaceable fuse?
A5: The internal 2A slow-blow fuse is not user-replaceable. Contact Schneider Electric service for fuse replacement.
