The product is a 4-digit 3-group display programmable switching DC regulated power supply, which can display voltage, t, and power at the same time. Products are widely used in mobile phone repair, computer repair, battery charging, school teaching and production line use. The output voltage and output t can be continuously adjusted between 0 and the nominal value using the code potentiometer, and the set value can be pre-displayed, which is convenient for use and adjustment. The stability and ripple coefficient of the power supply are very good. It’s of small size, beautiful design, convenient operation, can work for a long time at full load. Note: Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
