787-833 WAGO Industrial Automation Components

Wago 787-833 is a power supply unit featuring a pro switch-mode AC/DC power supply unit (SMPS PSU) with capabilities for TopBoost, PowerBoost, and both series and parallel operations. It operates with a supply voltage range of 120-300Vdc and an AC supply voltage of 85-264Vac, accommodating various input voltages such as 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. The unit is equipped with CAGE-CLAMP spring connections for secure and reliable connectivity. It offers a rated current of 5A, with PowerBoost capabilities of 10A for 4 seconds, 7.5A for 8 seconds, and a TopBoost function providing 30A for 25 milliseconds. The rated power of the unit is 240W. Designed for a wide range of operating temperatures, it functions efficiently between -25°C and +70°C, with storage temperatures ranging from -25°C to +85°C. The device ensures protection with an IP20 rating and includes a T 6.3A / 250Vac internal fuse for TopBoost/PowerBoost and constant current mode, alongside short-circuit and open circuit protection features. It also has a 1.1 x Io nom (typ.) current limitation function. The unit's dimensions are H163mm x W57mm x D179mm, suitable for DIN-35 rail mounting, and it is designed for single-phase AC (1AC) or DC operation with a frequency range of 50-60 Hz. The 787-833 is part of the Pro series and is set to be replaced by models supporting 48Vdc (SELV) and adjustable 33-52Vdc outputs. It has a power dissipation/loss of 20ms at 230Vac input and a minimal output error of 1%, with an output voltage ripple of 70mVpp. The unit is designed to operate within a humidity range of 5-96% RH without condensation.
