Key feature The constant voltage and constant current programmable  control power supply module is cabinet and delicate, and it put the collection  of analog integration and digital control functions in one. Its adjustable output voltage range is 0-20.0V, step  by 0.1V. Its adjustable output current range is 0-2.00A, step by 0.01A. Boot voltages can be stored freely and the model has  two groups of quick storage voltage. Compared with the traditional analog power supply, it  is more convenient to quickly extract the voltage or current required. LCD display, with function of voltmeter and ammeter.  It is easy to view the preset voltage, input voltage, output voltage, the preset  current, output current, output power and LCD brightness. Backlight brightness is adjustable. Data protection during power loss.
