787-1020 WAGO Industrial Automation Components

Wago 787-1020 is a compact switch-mode AC/DC power supply unit (SMPS PSU) that allows for both series and parallel operation. It features a relay contact output with status indication (DC OK) and is designed for a supply voltage range of 120-300Vdc with a rated current of 5.5A and 3.5A in any mounting position. The unit offers a rated power of 27.5W and can operate with an AC supply voltage of 85-264Vac, including 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. It is equipped with CAGE-CLAMP spring connections and has a design that includes DC-OK relay contact output. The power supply unit operates efficiently within an ambient air temperature range for operation of -25°C to +60°C and for storage from -25°C to +80°C. It supports a control voltage (AC) with a T 2A / 250Vac internal fuse and features constant current, short-circuit protection, open circuit protection, and a 1.1 x Io nom (typ.) current limitation function. The unit is designed for mounting on a DIN-35 rail, has dimensions of H89mm x W72mm x D59mm, and is suitable for single-phase AC (1AC) or DC operation. It has an IP20 degree of protection, a rated insulation voltage (Ui) of 72 mm, and includes features such as a response time of 80ms (230Vac input) and 10ms (110Vac input), with a power dissipation/losses of 0.29A (230Vac) and 0.56A (110Vac). The unit is designed to work within a humidity range of 5-96% RH without condensation and has an output voltage ripple of 100mVpp.
