ABB CP-C 24/20.0 Power Supply – 24V 20A Module

The ABB CP-C 24/20.0 (1SVR427026R0000) delivers a powerful and robust 24 VDC supply ideal for demanding industrial control systems. It provides a high-current output that supports large loads such as multiple PLC modules, sensors, actuators, and I/O devices. In addition, the module’s broad input voltage range and built-in protections ensure stable operation under varying supply conditions. This makes the unit a reliable core element for control cabinets, machine automation, and heavy-duty industrial panels.

2. Key Features and Main Benefits

• Delivers a substantial 480 W output at 24 VDC, supplying up to 20 A of current — enough to power intensive automation systems with many downstream devices. 

• Accepts a wide range of input voltages (AC 85–264 V or DC 100–350 V), ensuring compatibility across different power environments and reducing need for external converters. 

• Provides adjustable output voltage, enabling fine-tuning of supply between approximately 22–28 VDC to compensate for voltage drop over long feed lines. 

• Supports parallel operation for increased capacity or redundancy, helping to scale power delivery or build fault-tolerant systems. 

• Built-in protections (overload, short circuit, and power-factor correction) safeguard both the supply and connected devices under fault conditions.

4. Typical Applications / System Integration Use Cases

This power supply fits well in control cabinets powering programmable logic controllers (PLCs), distributed I/O, sensors, actuators and servo drives. It also supports systems requiring high combined current loads such as complex production machines or conveyor control lines. For example, OEM machine builders use it to power entire automation panels with many I/O and actuators. Moreover, its adjustable output and redundancy options make it ideal for systems demanding stable supply under heavy load or requiring high availability in manufacturing plants.

5. Reliability, Service and Maintenance

ABB builds the CP-C range with long-term durability in mind, ensuring stable performance even under fluctuating input voltage or heavy current draw. The inclusion of safety protections and power-factor correction reduces stress on internal components, which prolongs lifetime and minimizes maintenance frequency. In addition, global compliance certifications and adherence to standards facilitate smooth integration into industrial control infrastructure. Should replacement or expansion be necessary, parallel operation simplifies upgrades without major rewiring.
