ABB’s latest CP-S.1 power supplies are designed to meet the demanding requirements of modern machine building applications, combining high efficiency, reliability and a compact footprint. With an integrated 150% power reserve for up to five seconds and efficiency levels of up to 94%, they provide dependable performance even during peak load conditions.

The range features overheat protection and active power factor correction, along with a wide AC and DC input voltage range and comprehensive global approvals, including UL listing and marine certifications. This makes the CP-S.1 series a versatile and professional choice for DC applications worldwide.

Each CP-S.1 unit delivers a rated output voltage of 24 V DC, adjustable via a front-mounted ‘OUTPUT Adjust’ rotary potentiometer. Models are available with rated output currents of 3.0 A, 5.0 A, 10 A, 20 A and 40 A, covering a power range from 72 W to 960 W. The rated supply voltage range is 100–240 V AC or 100–250 V DC.

With typical efficiency of up to 94%, the units offer low power dissipation and minimal heat generation. Cooling is achieved through free convection, eliminating the need for forced ventilation. They operate within an ambient temperature range of -25°C to +60°C without derating, and up to +70°C with derating. The power supplies are open-circuit, overload and short-circuit stable, and include an integrated input fuse for added protection.

For critical applications requiring true redundancy, optional CP-C.1-A-RU redundancy units are available as accessories. A front-facing LED provides clear status indication, while a transistor DC OK signalling output (13–14) enables remote monitoring.
