Seamless integration with ABB CP-S.1 power supplies

EPD24 is a perfect companion for CP-S.1 power supplies range. 

Both designed for a huge variety of applications they perfectly fit thanks to a series of common features. Their frontal low wiring position and thin width fits perfectly into any enclosure. Plus, both devices feature the lowest power loss on the market and the same tripping behavior, allowing an unparalleled integration.

The all-new CP-S.1 power supplies are a preferred choice for multiple industrial applications:

  • Complete 24 V DC offering from 3 A up to 40 A in metal enclosure suits perfectly to OEM machine building requirements
  • Saves the valuable installation space of the control cabinet due to compact design and high efficiency
  • Coated PCBA and marine certification enables usage for e.g. wind, solar, marine applications
