- Switched-mode power supply
- Natural convection cooling when horizontally mounted
- Stepped profile, ideal for distribution boards or distribution boxes
- Overhead mounting is possible with derating
- Suitable for both parallel and series operation
- Electrically isolated output voltage (SELV) per EN 60950-1/UL 60950-1; PELV per EN 60204
The compact switch-mode AC/DC power supply unit (SMPS PSU) from WAGO's Compact series is DNV approved and provides a 24Vdc (SELV) output at 4A/96W. It accepts an input voltage range of 85-264Vac or 120-300Vdc, suitable for single-phase AC or DC. The unit features CAGE CLAMP spring connections and is designed for DIN-35 rail mounting with a width of 90mm. It has an IP20 protection rating and operates in ambient temperatures from -25°C to +60°C. This model replaces the obsolete 787-1122 component and is equivalent to the 7871022.
