Description: 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 0-32.00V, 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. Specification: Input voltage range: 6.00-40.00V Output voltage range: 0V-32.00V Output current: 0-5.000A Output power range: 0-160W Display module size: 79*43*41(mm) (L*W*H) Open size: 71mm*39mm Power module size: 93*71*41(mm) (L*W*H) Length of connecting line: 200mm Fixed hole center distance: 86mm, 64mm Max allowable input current: 10A Output ripple: about 100mVpp Output voltage program and read back resolution: 0.01V Output current program and read back resolution: 0.001A Output Voltage program and read back accuracy: ± (0.5% + 1 digit) Output Current program and read back accuracy: ± (0.5% + 3 digits) Temperature of the application environment: -10°c ~45°c Package Includes: 1 Piece Programmable Power Supply Module Note: 1, when you get the product in the first time, please don't use your hands to touch the components, because human static electricity can damage some chips. 2 .If you want to ensure output at full load, you must make sure that input is higher than 18V and 180W; pay attention to heat elimination at full load. 3. Connection between display part and power part should be according to the corresponding words. Otherwise it will not work by wrong connection 4, if you use AC-DC converter or transformer coil, please add rectifier (rectifier bridge) and filter (more than 4700uf filter capacitor). If input power supply is unstable, please add LC, L is over 47uf, C is over 2200 uf.
