787-2742 WAGO AC/DC Power Supplies

Wago 787-2742 is a power supply unit featuring an Eco switch-mode AC/DC power supply unit (SMPS PSU) capable of series operation with a maximum of 2 devices and parallel operation. It supports a supply voltage range of 560-700Vdc and an AC supply voltage of 325-575Vac, including 380Vac, 400Vac, 415Vac, and 480Vac, with a rated current of 20A and a rated power of 480W. The unit is designed with push-in CAGE-CLAMP spring connections for easy installation and offers a degree of protection of IP20. It operates efficiently within an ambient air temperature range for operation of -20°C to +70°C and for storage from -40°C to +85°C. The control voltage includes 3 x T 3.15A / 500Vac internal fuses for safety, featuring constant power in the overload range of 1.05 to 1.4 times the nominal output current (Io nom), and includes protections against short circuits, open circuits, with automatic restart in the event of a short circuit. The unit's dimensions are H130mm x W80mm x D170mm, suitable for mounting on a DIN-35 rail, and it is designed for use in 3-phase AC (3AC) or DC systems with a response time of 10ms for 3 x 400Vac input. The output voltage is adjustable between 22-28Vdc, with an output error of less than or equal to 1%, and it can handle power dissipation/losses efficiently. The coating material is designed to withstand 10-95% relative humidity without condensation.
