The product is a 4-digit 3-group display programmable switching DC regulated power supply, which can display voltage, current, 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 current 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. Features: Settable Voltage & Current, LED Display -- The code potentiometer sets the voltage and current, and the set value can be displayed in advance. Constant voltage and constant current switch automatically. 4-digit digital tube, voltage, current and power LED display, high precision. Safe Protections -- OVP over voltage protection, OCP over current protection, over temperature protection, short circuit alarm stop output. Auxiliary Functions -- USB fast charging function supports multiple fast charging protocols. With output on-off function. Cooling Fan, Compact Size -- The temperature-controlled fan has quick heat dissipation, low running noise and long lifespan. Small size, light weight, and high power density. Application Field -- Production line testing, repair of mobile phones/ computers/ electrical appliances, product aging and electroplating, battery charging, laboratory, scientific research, teaching, etc. Note: Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
