787-1634 WAGO AC/DC Power Supplies

Wago 787-1634 is a classic switch-mode AC/DC power supply unit (SMPS PSU) featuring TopBoost, with capabilities for series and parallel operation. It operates with a supply voltage range of 120-300Vdc and 85-264Vac, accommodating various AC inputs including 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. The unit is designed for a rated current of 20A and a rated power of 480W. Connection is facilitated through CAGE-CLAMP spring connections. It is built to function within an ambient air temperature range for operation of -25°C to +70°C and for storage from -25°C to +85°C. The power supply unit offers a degree of protection rated at IP20 and is equipped with a T 10A / 250Vac internal fuse for control voltage (AC), alongside features such as constant current, short-circuit protection, open circuit protection, and a 1.1 x Io nom (typ.) current limitation function. Its dimensions are H127mm x W95mm x D170mm, suitable for DIN-35 rail mounting. The EPSITRON Classic series part supports a single-phase AC (1AC) or DC supply, with an output of 24Vdc (SELV) and adjustable 23-28.5Vdc. Response times are noted at 20ms for a 230Vac input and 8ms for a 100Vac input, with a power dissipation/loss of 2.23A at 230Vac and 5.56A at 100Vac. The output error is within ±1%, and it operates efficiently within a humidity range of 5-96% RH, with no condensation permissible. The output voltage ripple is specified at 70mVpp.
