Schneider - 140CPS12420 Power Supply Module

Schneider Electric Modicon Quantum Redundant Power Supply Module

Core Product Overview

• This is a Schneider Electric 140CPS12420 power supply module.
• It is engineered for the Modicon Quantum automation platform.
• The module operates in both standalone and redundant modes for flexibility.
• It provides a regulated 5.1 V DC output to the backplane.
• A green PWR OK LED gives instant visual status confirmation.
• The standard module format allows for easy installation in any Quantum rack.

Electrical Input Specifications

• The module accepts a wide AC input range: 93...138 V AC at 115V nominal.
• It also supports 170...276 V AC at 230V nominal, 47-63 Hz.
• Maximum input current is 1100 mA at 115V and 600 mA at 230V.
• Inrush current is limited to 38 A (115V) or 19 A (230V) during power-up.
• The unit is protected by a 2 A, slow-blow internal fuse.
• It maintains low harmonic distortion, typically ≤ 10% of the fundamental.

Output Power & Protection Features

• Output current is 11 A in standalone mode at 60°C.
• In redundant mode, it delivers 10 A at 60°C for shared load operation.
• Internal circuits provide full overload and overvoltage protection.
• An integrated alarm relay (1 NC contact, 6A/220V) signals power supply faults.
• Power dissipation is calculated as 6 + (1.5 x Iout) watts for thermal planning.
• The total rated power capacity is 130 VA.

Environmental & Physical Data

• Designed for operation in ambient temperatures from 32 to 140 °F (0 to 60 °C).
• Storage temperature range is -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: Is the 140CPS12420 module new and authentic?
  A: Absolutely. Every 140CPS12420 we supply is 100% new and original from Schneider Electric.
• Q: What is the difference between standalone and redundant mode current?
  A: In standalone mode, it delivers 11A. In a redundant pair, each supplies 10A to share the load and provide backup.
• Q: What is the purpose of the alarm relay contact?
  A: The Normally Closed (NC) alarm contact opens if a power supply fault occurs. This allows for remote monitoring and integration into plant alarm systems.
• Q: Can this power supply handle both 115V and 230V inputs automatically?
  A: Yes. The 140CPS12420 auto-senses and operates across the full 93-276V AC range without manual switching.
• Q: What is your shipping and handling time?
  A> We process orders quickly, with items leaving our warehouse within 5 business days via express couriers.
• Q: Do you accept returns?
  A: We support a 30-day return policy for unused products in original condition. Please contact our team to initiate a return.
