140CPS21400 Power Supply Module | Schneider

Schneider Electric Modicon Quantum Summable DC Power Supply Module 140CPS21400

Electrical Input Specifications

• Input voltage range is a wide 20...30 V DC.
• Maximum input current draw is 3800 mA (3.8 A).
• Inrush current varies: 14 A at 20V and 25 A at 24V.
• It can handle input power interruptions up to 100 ms.
• The module is protected by a 5 A, slow-blow input fuse.
• This design supports reliable operation from DC sources like batteries or UPS.

Output Power & Protection Features

• Each module delivers up to 8 A of output current at 5.1V DC.
• Multiple 140CPS21400 units can be summed to provide higher total current.
• Comprehensive internal overvoltage and overload protection is included.
• The alarm output provides a Normally Closed (NC) contact (6A/220V) for fault signaling.
• Power dissipation is calculated as 6 + (1.8 x Iout) watts for thermal management.
• This makes it suitable for powering large, dense Quantum configurations.

Environmental & Physical Data

• Operating temperature range is 32 to 140 °F (0 to 60 °C).
• Safe storage temperature ranges from -40 to 185 °F (-40 to 85 °C).
• It performs at up to 95% relative humidity without condensation.
• Certified for use at altitudes up to 16,404 ft (5,000 m).

Frequently Asked Questions (FAQ)

• Q: What is the output current capacity?
  A: Each individual module provides 8 Amps at 5.1V DC. Multiple modules increase the total available current.
• Q: How is the alarm relay contact used?
  A: The NC alarm contact opens if a fault is detected. You can wire this to a PLC input or alarm panel for immediate system notification.
• Q: What is your shipping timeline?
  A: We ensure fast processing, with items leaving our warehouse within 5 business days via express courier services.
• Q: Do you accept returns on this item?
