Parameters: Working Voltage:DC 5V-30V Output Voltage:DC 0.5V-30V Output Power:35W Voltage Display Precision:1% Voltage Display Resolution:0.01V Current Display Precision:1.5% Current Display Resolution:0.001A Conversion efficiency:About 88% Work frequency:180KHz Over-temperature Protection:100? Working Temperature range:-20?~100? Working Humidity range:0%-95%RH Size:79*43*38mm Note: Input undervoltage protection voltage is 4.7V.Module need re-power if input less than 4.7V. Please rotate the CV potentiometer counterclockwise more than 15 turns if there is no output voltage. It is a DC power module,So it can not connect to AC power. Please connect input before connect battery when use as charge and make sure output voltage is higher than battery voltage. ’VIN-’ and ‘OUT-’ can not be connect together,otherwise module can not support constant current output. Please make sure input power is more than load power. Please step down output power if module is hot. Please read use manual and description before use. Application: Ordinary power supply Battery charger LED drive power Instrument voltage display Test meter Circuit test Power conversion
