787-740 WAGO Industrial Automation Components

Wago 787-740 is a power supply unit featuring an eco switch-mode AC/DC power supply unit (SMPS PSU) capable of series and parallel operation. It operates with a supply voltage range of 500-650Vdc and an AC supply voltage of 360-575Vac, including 380Vac, 400Vac, 415Vac, and 480Vac. This unit is designed with push-in CAGE-CLAMP spring connections and has a rated current of 10A and a rated power of 240W. The ambient air temperature for operation ranges from -25°C to +70°C, while the storage temperature range is from -40°C to +85°C. It offers a degree of protection rated at IP20 and includes 3 x T 2A / 250Vac internal fuses for control voltage (AC). The unit features constant power in the overload range of 1.15 to 1.4 times the nominal output current (Io nom), along with shutdown and automatic restart capabilities in the event of a short circuit, short-circuit protection, and open circuit protection. The dimensions are H130mm x W65mm x D130mm, suitable for DIN-35 rail mounting. It supports a 3-phase AC (3AC) or DC input and has a response time of 17ms for 3 x 400Vac input. The output voltage is adjustable between 22-28Vdc, with a power dissipation/losses at 3 x 1.2A for 400Vac input, and it maintains an output error within 1%. The unit is designed to operate within a humidity range of 10-95% relative humidity (RH) without condensation and has an output voltage ripple of 100mVpp.
