Product features
<br />   With advanced functions, high accuracy, wide application, the item is really practical for use.
<br />    This constant voltage & current programmable control power supply module makes analog integration and digital control functions combined in one.
<br />    With LCD display, you can view the preset voltage, input voltage, output voltage, preset current, output current, output power, etc.
<br />    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.
<br />    The output voltage is adjustable from 0 to 32.00V, the output current is adjustable from 0 to 5.000A. The module can storage 10 groups of preset value and it can quickly extract 2 groups of preset value.
