1SVR427045R0400 ABB CP-D 24/4.2 Power Supply 24 V DC 4.2 A 100 W

Why Choose the ABB CP-D 24/4.2 Power Supply?

The ABB CP-D 24/4.2, order code 1SVR427045R0400, is a compact primary switch mode power supply designed to provide reliable 24 V DC power for industrial automation, control and electrical distribution applications. Part of the ABB CP-D series, its modular DIN-rail component design is particularly well suited to distribution panels and control cabinets where efficient use of installation space is important.

The CP-D 24/4.2 delivers a rated 24 V DC output at 4.2 A with 100 W rated output power. Its output voltage is continuously adjustable from 24–28 V DC using the front-face potentiometer, allowing the supply to be adapted to connected equipment and helping compensate for voltage drops along longer cable runs.

A wide 90–264 V AC / 120–375 V DC input range, typical efficiency of 89%, free-convection cooling and a U/I output characteristic support dependable industrial operation. The unit is open-circuit, overload and short-circuit stable and incorporates an input fuse and LED indication of operational states.
