Description: This constant voltage and constant current programmable control power supply module makes analog integration and digital control functions combined in one. Its adjustable output voltage range is 0-50.00V, step by 0.01V. Its adjustable output current range is 0-15.00A, step by 0.01A. 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.

You must make sure that the input voltage is 1.1 times higher than output voltage. Under large current circumstances, pay attention to heat elimination. When the current is more than 10A or the temperature is more than 45 °c , the fan will begin to work. when the temperature is more than 65 °c, the module will stop working
