Product Overview
The ABB CP-S 24/5.0 1SVR427014R0000 is a primary switch mode power supply from the CP-S Series, intended for converting an AC supply into a regulated 24 V DC control voltage. It is commonly used as the DC power source for PLCs, relays, contactors, sensors, interface modules, and other control-circuit devices inside industrial control cabinets.
The 24 V DC output makes the unit suitable for conventional machine control as well as distributed automation panels where several control components share a common DC supply. Its role is primarily at the power-distribution level rather than in signal processing or controller logic.
In a typical cabinet, the CP-S 24/5.0 can be connected downstream of the AC protection and upstream of the 24 V DC control circuits. The output can feed several loads through separate terminal distribution points, allowing the power supply to serve as a central DC source for a machine or automation section.
For maintenance and replacement work, the complete order number 1SVR427014R0000 should be checked against the installed unit and the cabinet power requirements before substitution. Particular attention should be given to input supply compatibility, 24 V DC load requirements, wiring, and the protection arrangement on the DC side.

Working Principle
The CP-S 24/5.0 converts the incoming AC supply into a controlled 24 V DC output for connected automation equipment. Internally, the switching power stage operates at high frequency, allowing the incoming electrical energy to be converted and regulated before being delivered to the DC output terminals.
AC Supply → CP-S 24/5.0 → 24 V DC Output → Control Circuit Loads
The operating sequence can be understood as:
- The AC input enters the power supply through the designated input terminals.
- The input stage conditions and rectifies the incoming power for the switching circuit.
- The switching section transfers energy through the high-frequency conversion stage.
- The output stage rectifies and filters the converted energy to establish the DC supply.
- Regulation circuitry continuously controls the conversion process to maintain the required output voltage.
- The 24 V DC output is distributed to connected PLC, relay, sensor, interface, and actuator circuits.
When several devices share the same DC supply, the actual load current should be considered as the sum of the individual operating currents, with suitable allowance for startup and transient loads.
Role in an Industrial Control Power Architecture
The CP-S 24/5.0 normally sits between the protected AC distribution and the 24 V DC control layer of the automation cabinet.
AC Distribution → Circuit Protection → CP-S 24/5.0 → 24 V DC Distribution → PLC / I/O / Relays / Sensors
| System Element | Function |
|---|---|
| AC Circuit Protection | Protects the incoming power circuit |
| CP-S 24/5.0 | Converts the AC input into regulated 24 V DC control power |
| DC Distribution | Separates the 24 V DC supply into individual circuits |
| PLC | Executes machine or process control logic |
| I/O Modules | Interface field signals with the controller |
| Interface Relays | Provide electrical isolation or switching between circuits |
| Sensors | Supply process and machine status signals |
| Contactors / Actuators | Control motors and other field loads |
The power supply therefore forms the electrical foundation for the low-voltage control devices connected to the automation system.
Industrial Applications
| Application | Typical Use |
|---|---|
| PLC Control Cabinets | Supplying 24 V DC to PLC CPUs, I/O modules, and control accessories |
| Machine Automation | Powering sensors, relays, control interfaces, and auxiliary circuits |
| Motor Control Panels | Supplying control circuits associated with contactors and motor starters |
| Conveyor Systems | Providing DC power for sensors, control relays, and PLC interfaces |
| Pump Control Systems | Supporting control electronics and field instrumentation |
| HVAC Control Panels | Supplying controllers, sensors, relays, and actuator interfaces |
| Packaging Machinery | Central DC source for machine-control components |
| Process Automation | Supplying low-voltage control and signal-interface equipment |
| Electrical Control Panels | General 24 V DC distribution for cabinet-mounted devices |
Installation and Maintenance
- Verify the complete 1SVR427014R0000 order number before installation or replacement.
- Confirm that the available AC supply matches the permitted input configuration of the power supply.
- Isolate the upstream power before connecting or removing wiring.
- Use appropriately rated circuit protection on the input side.
- Connect the 24 V DC output with correct polarity.
- Separate power wiring from sensitive signal wiring where cabinet layout permits.
- Check the total connected DC load before commissioning.
- Consider startup current from connected devices such as relays, contactors, and electronic modules.
- Check terminal tightness during commissioning and scheduled maintenance.
- Inspect wiring for discoloration, loose terminals, insulation damage, or abnormal heating.
- Verify the 24 V DC distribution voltage under normal operating load.
- Keep the power supply free from excessive dust and ensure that cabinet ventilation is not obstructed.
If the connected equipment loses power unexpectedly, check the AC input first, then inspect the DC output and distribution circuit. If the output voltage falls when multiple loads are energized, the total load and individual branch circuits should be checked before replacing the power supply.

Technical FAQs
What is the main function of the ABB CP-S 24/5.0?
Its primary function is to convert the available AC supply into regulated 24 V DC power for industrial control equipment. Typical connected loads include PLCs, I/O modules, sensors, interface relays, and other control-circuit devices.
How should the load be evaluated before using the CP-S 24/5.0?
Calculate the operating current of all connected 24 V DC devices and consider simultaneous operation and startup demand. The selected power supply should have sufficient capacity for the actual control system rather than being sized only from the normal current of a single device.
Can the CP-S 24/5.0 supply both PLC equipment and field devices?
Yes, it can serve as a common 24 V DC source for multiple control-system loads when the total current remains within the power supply’s capacity. In larger cabinets, separate fused or protected branches are normally used for PLC electronics, sensors, relay circuits, and other loads.
What should be checked when replacing an installed CP-S 24/5.0?
Verify the complete model and order number, input supply requirements, 24 V DC load demand, terminal wiring, protection devices, and cabinet power-distribution arrangement. After installation, check the DC output under load and confirm that all connected control devices operate normally.
