140CPS21400C | Schneider 5.1V DC Power Supply Module

Introducing the Schneider 140CPS21400C Power Supply Module

When your control system demands reliable power, the 140CPS21400C from Schneider Electric's Modicon Quantum series stands ready. This power supply module accepts a 24V DC input (20...30V range) and provides a stable 5.1V DC output, ensuring your automation platform operates without interruption.

With an input current of 3800 mA and a summable output current of 8A, this module supports demanding loads while maintaining efficiency. Its robust design includes inrush current handling of 14A at 20V and 25A at 24V, protecting your system during power-on.

Key Features and Technical Specifications

• Input voltage: 24V DC (20...30V range) for flexible power sources.
• Input current: 3800 mA, ensuring adequate power draw.
• Output voltage: 5.1V DC, stable for sensitive electronics.
• Output current: 8A summable, supporting multiple loads.
• Inrush current: 14A at 20V, 25A at 24V for reliable startup.
• Max input power interruption: 100 ms (1 ms at 20V) for ride-through capability.
• Associated fuse rating: 5A slow-blow, protecting the module.
• Resistance to electromagnetic fields: 10 V/m at 80...2000 MHz (IEC 801-3).
• Operating temperature: 0...60°C, suitable for industrial environments.
• Relative humidity: up to 95% without condensation.

One distinctive spec is the 8A summable output current, which allows you to combine outputs for higher total current, reducing the need for additional power supplies and lowering overall system cost.

Applications and Use Cases

In manufacturing plants, the 140CPS21400C powers PLC I/O modules, sensors, and actuators. Its wide input range accommodates battery-backed systems, while the high output current supports multiple devices simultaneously. For example, in a packaging line, this module can power several control cards, reducing downtime and maintenance costs.

Installation and Setup

Mount the module on a standard DIN rail or panel, ensuring adequate airflow. Connect the 24V DC input to the designated terminals, observing polarity. Use a 5A slow-blow fuse in the input line as specified. After wiring, verify the output voltage with a multimeter before connecting loads.

Maintenance and Reliability

Regularly inspect the module for dust accumulation and ensure ventilation is unobstructed. Check input voltage stability and fuse integrity periodically. The conformal coating (Humiseal 1A33) protects against moisture and corrosion, extending service life and reducing replacement costs.

Compatibility and Integration

Designed for the Modicon Quantum automation platform, this power supply integrates seamlessly with Quantum backplanes and I/O modules. It is CE marked and certified to UL 508 and CSA C22.2 No 142, ensuring compliance with North American standards.

Troubleshooting and Common Issues

If the output voltage is absent, check the input fuse and verify input voltage is within 20...30V DC. The green PWR OK LED indicates normal operation; if it is off, inspect the power source. For persistent issues, consult the Schneider manual or contact Petro Auto Tech.
