ABB CP-D 24/4.2 DIN Rail Power Supply 24V DC 4.2A 100.8W 1-Phase 1SVR427045R0400

Industrial control systems need a stable 24V DC supply that fits directly on a DIN rail without extra mounting hardware. The ABB CP-D 24/4.2 delivers 4.2 A at an adjustable 24–28 V DC, with a wide 100–240 V AC input that keeps single-phase installations simple.

Who is it for

Panel builders, machine OEMs, and maintenance teams who want a compact, convection-cooled power supply for PLCs, sensors, relays, and other 24V control loads. It suits cabinets where space is limited and reliable operation matters more than fieldbus features.
