2687-2142 WAGO Industrial Automation Components

Wago 2687-2142 is a power supply unit featuring an Eco2 switch-mode AC/DC power supply unit (SMPS PSU) capable of series and parallel operation. It includes LED status indication for DC OK and utilizes push-in CAGE-CLAMP spring connections for easy installation. This unit has a rated current of 1.25A and a rated power of 30W, with a supply voltage range of 90-264Vac, accommodating various AC inputs such as 110Vac, 120Vac, 220Vac, 230Vac, and 240Vac. It is designed to operate within an ambient air temperature range of -25°C to +70°C and can be stored in temperatures ranging from -40°C to +85°C. The unit offers a degree of protection rated at IP20 and features a rated insulation voltage (Ui) of 25 mm. It includes a T 1A / 250Vac internal fuse for control voltage (AC), supports constant power up to 125%, and is equipped with protection mechanisms against short circuits, open circuits, and automatic restart capabilities. The unit's dimensions are H100mm x W25mm x D90mm, and it is designed for single-phase AC (1AC) operation with a frequency range of 50-60 Hz. The output voltage is adjustable between 22-29Vdc, with power dissipation/losses timed at 120ms for 230Vac and 15ms for 110Vac. The unit ensures an output error of ≤1% and can operate in environments with 5-96% relative humidity, provided there is no condensation.
