General Information: Digital Control Buck-Boost Supply Power Module put the collection of analog integration and digital control functions in one. Its adjustable output voltage range is 0-50.00V, step by 0.01V. Its adjustable output current range is 0-5.000A, step by 0.001A. 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 of 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 group and LCD brightness. This module adopts buck-boost structure; when input voltage is lower than, equal to or higher than output voltage, output voltage is still stable and changeless. This feature has wide range of application. Notice: 1.Before buying this product, please download the upper computer software and test, if it fits your computer, you can buy 2. the upper computer only support For Win7 and above PC software & manual: Download here!

Connection between display part and power part should be according to the corresponding words. Otherwise it will not work by wrong connection Connection description: IN+: Input positive IN-: Input negative: OUT+: Output positive: OUT-: Output negative Note: Input voltage range is DC 6-50V and 50V is the limit voltage; please leave a room to use. Or else it will be burnt. The input must be DC power supply, not AC 220V, or else it will be burnt too. Though this module has reverse connection protection and output short circuit protection, you can muse be in strict accordance with connection description to connect. If you connect the supply power with output, the module will be burnt.
