787-1628 WAGO AC/DC Power Supplies

Wago 787-1628 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 254-780Vdc and an AC supply voltage of 180-550Vac, accommodating various input voltages such as 240Vac, 380Vac, 400Vac, 415Vac, and 480Vac. The unit is designed for a rated current of 5A and a rated power of 120W. 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 unit offers a degree of protection rated at IP20 and is equipped with a T 3.15A / 500Vac internal fuse for control voltage (AC), alongside features like constant current, short-circuit protection, open circuit protection, and a 1.1 x Io nom (typ.) current limitation function. The dimensions are H127mm x W42mm x D143.5mm, suitable for DIN-35 rail mounting. It supports a control voltage (DC), with a response time of 126ms for 500Vac input and 15ms for 200Vac input. The product is designed for either single-/2-phase or DC operation, with a power dissipation/loss as specified. The output error is less than or equal to 1%, and it operates efficiently within a humidity range of 5-96% RH, with no condensation permissible. The output voltage ripple is 30mVpp.
