1SVR427060R0300 ABB CP-B 24/3.0 Buffer Module 24 V DC 3 A 1000 Ws

Why Choose the ABB CP-B 24/3.0 Buffer Module?

The ABB CP-B 24/3.0, order code 1SVR427060R0300, is an ultra-capacitor buffer module designed to maintain a 24 V DC supply during short interruptions or voltage drops on the primary side of an industrial power supply. Part of the ABB CP-B range, it provides short-term uninterrupted DC power without the routine maintenance associated with conventional battery-based backup systems.

The CP-B 24/3.0 is rated for 24 V DC and 3 A and incorporates a minimum internal energy storage capacity of 1,000 Ws (1 kWs). When the normal supply is interrupted, the stored capacitor energy is automatically made available to the connected load, helping controllers, relays, instrumentation and other critical equipment continue operating through temporary supply disturbances.

Ultra-capacitor technology provides a maintenance-free energy storage solution without deep-discharge concerns. The module also offers efficiency above 95%, LED status indication, relay contacts for status messaging, short charging times and an extended -40 to +60 °C operating temperature range, making it suitable for demanding industrial environments.

Key Advantages

• Buffers 24 V DC industrial power systems during short supply interruptions.

Maintenance-Free Ultra-Capacitor Backup for 24 V DC Systems

The ABB CP-B range uses ultra-capacitor energy storage to bridge temporary interruptions in the normal DC power supply. Unlike conventional battery-backed systems, the CP-B 24/3.0 does not rely on a chemical battery, helping eliminate battery replacement and deep-discharge concerns while providing rapid charging and dependable short-term energy storage.

With a minimum stored energy capacity of 1,000 Ws, the CP-B 24/3.0 can typically maintain its full 3 A load for approximately 13 s, with considerably longer buffering available at lower load currents. This makes it particularly useful for bridging short mains failures, allowing controlled equipment to ride through supply disturbances or complete an orderly shutdown sequence.

Typical Applications

• 24 V DC industrial automation systems.
• PLC and machine-control systems.
• Short-term backup for critical control circuits.
• Bridging mains interruptions and voltage drops.
• Industrial instrumentation and monitoring equipment.
• Process automation installations.
• Solar and renewable-energy control applications.
• Systems requiring maintenance-free DC energy buffering.
