787-1702 WAGO AC/DC Power Supplies

Wago 787-1702 is a power supply unit featuring an Eco switch-mode AC/DC power supply unit (SMPS PSU) capability. It allows for series operation with two devices of the same type and parallel operation. The unit operates with a supply voltage range of 125-375Vdc and an AC supply voltage of 90-264Vac, accommodating various AC inputs including 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. It is equipped with CAGE-CLAMP spring connections for secure wiring and offers a rated current of 1.25A with a rated power of 30W. The ambient air temperature for operation ranges from -20°C to +60°C, while for storage, it can handle -25°C to +75°C. The device features IP20 protection and includes a 30 mm rated insulation voltage. It is designed for single-phase AC (1AC) or DC operation and comes with a built-in F 1A / 250Vac internal fuse for safety. The unit ensures constant power in the overload range of 1.05 to 1.4 times the nominal output current and includes protections against short circuits and open circuits, with automatic restart in the event of a short circuit. It is suitable for mounting on DIN-35 rail or wall (screws) and has dimensions of H90mm x W30mm x D99mm. The power supply unit supports a control voltage of 24Vdc (SELV) and an adjustable range of 22-26Vdc, with a power dissipation/losses time of 10ms at 230Vac input. It is designed to operate within a humidity range of 10-95% RH without condensation and has an output voltage ripple of 200mVpp.
