Wago 787-1634/000-070 is a classic switch-mode AC/DC power supply unit (SMPS PSU) that allows for both series and parallel operation. It features LED status indication for DC OK and includes 1 x DC OK contact (NO Normally Open make contact) with a supply voltage of max. 30Vac/dc 1A. The connection type is specified for 120-300Vdc with CAGE-CLAMP spring connections as the rated current method. It supports a rated voltage of 20A and has a resistance of 480W. The supply voltage (AC) ranges from 85-264Vac, accommodating 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. Designed for operation in ambient air temperatures of -25°C to +70°C and storage temperatures of -25°C to +85°C, it offers a degree of protection of IP20. The unit measures 127mm in height, 95mm in width, and 170mm in depth, suitable for mounting on a DIN-35 rail. It includes features such as a T 10A / 250Vac internal fuse, constant current, short-circuit protection, open circuit protection, and a 1.1 x Io nom (typ.) current limitation function. The power supply operates on a single-phase AC (1AC) or DC, with a frequency range of 44-66 Hz and provides a 24Vdc (SELV) output, adjustable between 23-28.5Vdc. The trip current rating is 20ms for 230Vac and 8ms for 100Vac, with a diameter of 2.23A for 230Vac, 5.56A for 100Vac, and 30A. It is designed to operate within a humidity range of 5-96% RH without condensation and has an output voltage ripple of 70mVpp.
