LCD Constant Voltage Current Step -down Programmable Power Supply Module Part Description: Input voltage range: 6-40.00V Output voltage range: 0V-32.00V Output current: 0-5.100A Output power range: 0-160W Product Weight: 66g Product Dimension: Approx . 85*58*31( mm ) (L*W*H)/ 3.35x 2.28x 1.22inch Output voltage resolution: 0.01V Output current resolution: 0.001A Output Voltage accuracy: ± (0.5% 1 digits) Output Current accuracy: ± (1% 3 digits) Wave (full load 40v to 32V/5A): about 100 mV VPP Detachable LED display Note: On the of output, the Input must V higher than the output. Please strengthen the heat dissipation when working with big current. Specifications: 1. Open or close output: press ON/OFF button time to open or close output in any state; press again, output will be closed or open, followed by recycling. When closed output, the LED display will show “OFF”. 2. Set output voltage and current: Press SET shortly, the led display will be blinking. You can press the two buttons ( key and - key ) on the tube left to increase or decrease the value. Press SET key shortly again to switch 0.01V to 0.1V to 1V to 0.01A to 0.1A to 1A to exist adjustment, followed by recycling. At the corresponding , you can press the two buttons ( key and - key ) to increase or decrease the value. if you don't press the set key , the set mode will be automatically exited after 6s and the current set value will be automatically stored. 3. Switch input and output display: At no output state, press the two buttons on the tube left ( IN key and ) to switch the tube display between the current input voltage and the current output voltage . When show input voltage , “ IN ” LED lights; when show output voltage , “OUT” LED lights. 4. and CV indication: When the module is in the state of constant voltage ( CV ) or constant current ( ), the or CV led will lights correspond to show CV state. 5. Output current zero calibration: In the state, Keep pressing SET key to power on, when the led display flashed, the calibration is done. Then you can loosen the SET key . 6. value automatically: in operation process, the led display state, output current and output voltage setting value and output state are automatically stored. When power time, the default work state is the stored state Package Includes: 1 Piece Power Supply Module
