Features: This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one. The output voltage is adjustable from 0V-32V/0-50.00V, the output current is adjustable from 0-5.000A/0-12.00A/0-15.00A . The module can storage 10 groups of preset value and it can quickly extract 2 groups of preset value. With LCD display and the function of voltage and current meter, you can view the preset voltage, input voltage, output voltage, preset current, output current, output power, etc. In the output state display area, it is convenient for you to know whether the output works, constant voltage/current output state, current data group extracted, etc. With advanced functions, high accuracy, wide application, the item is really practical.
