ABB 1SVR427026R0000 CP-C 24/20.0 Power Supply Module

Description

Engineered to deliver highly regulated DC control voltage in demanding industrial automation networks, the ABB 1SVR427026R0000 belongs to the high-performance CP-C series of primary switch-mode power supplies. This module converts a wide-range AC or DC input into a stable 24 VDC nominal output, rated for a continuous output current of 20 A. Equipped with active Power Factor Correction (PFC) compliant with EN 61000-3-2 standards, it minimizes harmonic distortion and enhances system power quality. The adjustable output voltage range allows for precise line-drop compensation across long cable runs, while pluggable termination blocks simplify installation and field replacement.

Features

• Wide Input Range: Seamlessly operates on input voltages from 85 to 264 VAC and 100 to 350 VDC.
• Adjustable Output: Nominal 24 VDC output is adjustable between 22 and 28 VDC via a front-facing potentiometer.
• Power Reserve: Features an integrated 10% continuous power reserve (up to 22 A) to handle high-inrush startup loads.
• Active PFC: Built-in power factor correction reduces network feedback and line losses.
• Parallel Configurable: Supports direct parallel connection of multiple units for capacity expansion or N+1 redundancy.
• Pluggable Connections: Detachable screw-terminal blocks reduce downtime during maintenance procedures.

Applications

• Distributed Control Systems (DCS) and Programmable Logic Controller (PLC) cabinet power distribution.
• Process automation systems in petrochemical, water treatment, and heavy manufacturing facilities.
• Automated assembly lines, material handling systems, and packaging machinery.

Connections and Interfaces

Alternative Models & Compatibility

The CP-C 24/20.0 power supply features compatibility with modular system expansions. It can be paired with the CP-C CO Redundancy Unit for load-sharing configurations and the CP-C MM Messaging Module to provide real-time status relay outputs. This unit serves as a direct functional drop-in for legacy 24V 20A switch-mode modules requiring standard TH35 DIN rail mounting.

Application Pitfalls & Engineering Notes

To prevent localized thermal overloading inside sealed electrical enclosures, maintain a minimum installation clearance of 10 mm horizontally from adjacent DIN rail devices and 80 mm vertically above and below the ventilation slots. When configuring parallel installations, ensure the output voltage of each power supply is manually matched under identical load conditions to prevent uneven current distribution.

Commissioning & Wiring Tips

Utilize wire ferrules for all connection cables to prevent loose strands from short-circuiting. The pluggable terminals on the CP-C series require a standard slot-head screwdriver; tighten to a nominal torque rating of 0.6 Nm to maintain a secure electrical contact under full 20 A loading. Verify that the protective earth (PE) terminal is securely bonded to the system backplate prior to applying main power.
