787-734 WAGO Industrial Automation Components

Wago 787-734 is a power supply unit featuring an eco switch-mode AC/DC power supply unit (SMPS PSU) capable of both series and parallel operation. It accepts a supply voltage range of 130-373Vdc and 85-264Vac, including 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac, with a rated current of 20A and a rated power of 480W. The unit is designed for push-in CAGE-CLAMP spring connections and operates within an ambient air temperature range of -25°C to +70°C for operation and -25°C to +85°C for storage. It offers a degree of protection rated at IP20 and features a rated insulation voltage (Ui) of 115 mm. The power supply unit includes a T 10A / 250Vac internal fuse, supports constant power in the overload range of 1.15 to 1.4 times the nominal output current (Io nom), and provides shutdown and automatic restart in the event of a short circuit, alongside short-circuit and open circuit protection. The unit's dimensions are H136mm x W115mm x D144mm, designed for single-phase AC (1AC) or DC input with a response time of 20ms at 230Vac input. It offers a trip unit type of ≤1% (output error) and can withstand up to 95% relative humidity without condensation. The output voltage ripple is specified at 100mVpp.
