787-1623 WAGO AC/DC Power Supplies

Wago 787-1623 is a classic switch-mode AC/DC power supply unit (SMPS PSU) designed for versatility and efficiency in automation systems. It supports both series and parallel operations, enhancing its application range. The unit features a relay contact output with status indication (DC OK) for monitoring purposes. It operates with a supply voltage range of 120-300Vdc and 85-264Vac, accommodating various input requirements. The connection is facilitated by CAGE-CLAMP spring connections for secure and maintenance-free wiring. With a rated current of 2A and a rated power of 96W, it ensures adequate power supply for connected devices. The design includes a DC-OK relay contact output for reliable operation feedback. It operates efficiently within an ambient air temperature range for operation of -25°C to +70°C and for storage from -25°C to +85°C. The unit is equipped with a T 4A / 250Vac internal fuse, constant current mode, short-circuit, and open circuit protection, alongside a 1.1 x Io nom (typ.) current limitation function for enhanced safety. Its compact dimensions are H90mm x W52mm x D119mm, suitable for DIN-35 rail mounting. The power supply unit is designed for single-phase AC (1AC) or DC input, with a response time of 80ms at 230Vac input and 15ms at 100Vac input. It features an IP20 degree of protection, ensuring it is safeguarded against solid objects larger than 12.5mm but not against liquids. The rated insulation voltage (Ui) is 52 mm, and it has a control voltage (AC) with a 0.97A (240Vac) and 1.84A (100Vac) type of lens. The unit's power dissipation/losses and resistance are optimized for efficiency, with a trip unit type of ≤1% (output error) and a coating material designed to withstand 5-96% relative humidity (RH), with no condensation permissible.
