This module has power-down stored function and can store 10 groups preset value. And it also has the function of extracting quickly two groups stored value.Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc. On the output state remind area, you can see that output opens or not, the state of constant voltage and constant current, output is normal or not, the key is locked or not, and the current data groups that is being used.On the setting data interface, you can adjust overvoltage value, overcurrent value, over-power value, data set and LCD brightness.Specifications:Material: plastic, metal.Color: show as pictures.Input voltage range: 6-60V.Output voltage range: 0V-50.00V.Output current: 0-20.000A.Output power range: 0-1000W.Output voltage program and read back resolution: 0.01V.
