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 2.5A and 60W. It supports 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 72mm. It has an IP20 rating and operates in ambient temperatures from -25°C to +60°C. This model replaces the obsolete 787-1112 component and is equivalent to the 7871012.
