CP-C.1 24/20.0 1SVR360763R1001 ABB Power Supply

The ABB CP-C.1 24/20.0 1SVR360763R1001, also cataloged as the CP-C.1 24/20.0 Switch Mode Power Supply, operates as a dedicated hardware component for direct current voltage conversion and power delivery within industrial automation cabinets. The module transforms wide-range AC or DC input voltages into a regulated 24 VDC bus supply, providing power reserves for control electronics, PLC racks, and field instrumentation.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Flash Compatibility

Although operating primarily as an independent power supply unit, the CP-C.1 series provides integrated signaling outputs and voltage monitoring interfaces for diagnostic backplane integration. The unit features built-in power reserve characteristics following a U/I output curve, allowing reliable starting of heavy inductive or capacitive loads across deterministic control networks. Internal solid-state electronics maintain low harmonic distortion and high efficiency across extended operational temperature ranges without requiring firmware flash interaction.

Frequently Asked Questions

Q: What are the minimum clearance distances required around the unit for adequate thermal dissipation?

A: Maintain a minimum mounting distance of 25 mm horizontally and vertically between the power supply and adjacent electrical conductive boards or neighboring devices of the same type.

Q: Can this unit operate directly from a high-voltage DC supply rail?

A: Yes. The input stage accepts a continuous operating voltage range of 90 ... 300 VDC as well as 85 ... 264 VAC, permitting operation from DC station battery banks.

Q: What are the specified wire stripping lengths and terminal tightening torques for wiring installation?

A: For the input circuit, strip wires to 8 mm and tighten to 0.5 Nm using a PH1 screwdriver. For the output circuit, strip wires to 10 mm and tighten to 1.2 Nm.

Field Installation Guidelines

1. Mount the unit on a standard TH35-7.5 or TH35-15 (35 mm) DIN rail according to IEC 60715 in vertical orientation (Position 1).
2. De-energize all primary input AC/DC power lines before connecting wiring to prevent electrical shock or terminal damage.
3. Connect input lines using rigid conductors (0.5 ... 4 mm2) or flexible wires with ferrules (0.5 ... 2.5 mm2). Ensure proper connection of the protective earth (PE) terminal.
4. Wire the 24 VDC output using heavy-gauge conductors (rigid 2.5 ... 16 mm2 or flexible 2.5 ... 10 mm2) to handle continuous load currents up to 26 A without excessive voltage drop.
5. Verify that ambient panel temperature around the unit remains within -25 to +70 deg C during operation and maintain the 25 mm horizontal and vertical clearance spaces.
