787-914 WAGO Industrial Automation Components

Wago 787-914 is a power supply unit (PSU) designed for fan control, capable of both series and parallel operation. It operates with a supply voltage range of 130-373Vdc and can accommodate an AC supply voltage of 90-264Vac, including 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. The unit features CAGE-CLAMP spring connections for secure and efficient connectivity. It is rated for a current of 1A and is designed to function within an ambient air temperature range for operation of -25°C to +60°C and for storage from -25°C to +75°C. The PSU is equipped with a control voltage (AC) of 1A / 250Vac internal fuse and offers constant power in the overload range of 1.05 to 1.7 times the nominal output current (Io nom), with hiccup mode for short circuit or permanent overload situations, as well as short-circuit and open circuit protection. It has an IP20 degree of protection and a rated insulation voltage (Ui) of 45mm. The unit's dimensions are H138mm x W45mm x D35mm, and it supports a control voltage (DC) with a response time of 15ms. The power dissipation/losses are managed with a trip unit type of ≤1% (output error), and it is designed for mounting on DIN-35 rail or directly onto a wall with screws. The PSU is designed to replace models with output voltages of 22Vdc and adjustable ranges between 12-22Vdc, featuring a coating material that allows for operation in environments with 20-90% relative humidity, without condensation. The output voltage ripple is specified at 100mVpp.
