Modular Power Supply -Adjustable Power Supply Module, Step-Down Module Highlights Generic Brand Adjustable Power Supply Module, Step-Down Module 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) Ripple (full load 40v to 32V / 5A): about 100 mV VPP Detachable LED display Note: On the state of the output, the input must be higher of 1 V at the output. Please strengthen heat dissipation when working with large current. Specification: 1. Open or close the output: press the ON/OFF button once to open or close the output in any state; press again, the output will be closed or open, followed by recycling. When the output is closed, the LED display will show \""OFF\"". 2. Set output voltage and current: Short press SET, the LED display will flash. You can press the two buttons (+ and - key) on the left tube to increase or decrease the value. Short press the SET key again to switch from 0.01V to 0.1V to 1V to 0.01A to 0.1A to 1A to adjust, followed by recycling. At the place of the corresponding value, you can press the two buttons (+ and - key) to increase or decrease the value. If you do not press the Set key, the setting mode will be automatically exited after 6s and the current setting value will be automatically saved. 3.Registration of switch input and output: When there is no output state, press the two left tube buttons (IN key and OUT key) to display of the tube between the current input voltage and the current output voltage. When the input voltage is displayed, the \""IN\"" LED lights up; When the output voltage is displayed, the \""OUT\"" LED lights up. 4. CC and CV indication: When the module is in the constant voltage (CV) or constant current (CC) state, the CC or CV LEDs light up to indicate the CV or CC state. 5. Output current zero calibration: In the no-load state, press and hold the SET key to power on, when the LED display flashes, the calibration is complete. Then you can loosen the SET key. 6.Store set value automatically: In the process of operation, LED display status, output current and output voltage set value and output status are automatically stored. When power on next time, the default working state is stored state Package includes: 1 Piece Programmable Power Module Note: Due to the light and light setting difference screen, the item\`s color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
