WYJ series DC power supplyDetailed product description：

The WYJ series DC power supply is a high-precision DC power supply with stable voltage and stable current automatic conversion. The performance indicators of this product fully comply with the SJ2811.1-87 and SJ2811.2-87 standards. When in a stable voltage state, the output voltage of the power supply can be adjusted from 0V and can be adjusted freely within the rated range, and the current limiting protection point can also be selected arbitrarily; When in a steady current state, the power output current is continuously adjustable within the rated range. Widely used in industrial production, laboratories in universities, research institutes, postal and telecommunications, and automation equipment.
