This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one. This module has power-down stored function that it can store 10 groups of preset values and extract 2 groups of stored values. With LCD display, user can view the preset voltage/current, output voltage/current, output power, input voltage, etc. This product, with small size, multiple functions, good visual effect, high operability, and high precision, can not only be used independently, but also inset into the device for wide application range. Note: It is better to make the input voltage lower than the Max. value, otherwise the item maybe be damaged.
