WHDTS DC Buck Boost Power Supply Module DC 5V30V to DC 06V30V 35W 4A CVCC Adjustable Automatic Step UP Down Voltage Converter LCD Display

The DC adjustable CVCC constant voltage constant current buck boost power supply module with LCD displaycan display input /output voltage, current, power, display status, capacity, energy and time. It supports solar charging and can be connected to solar battery. This tiny electronics module can be used as A Normal Buck /Boost Power Supply Module, A Charger and A LED Constant Current Driver. Efficient and Practical. Using Steps: Please check product images and download "User Manual" on Product Page Named "Technical Specification" Section (Due To Character Limit) for specific instruction. Wide Application: ?Boost/Buck Power Supply Module; ?Battery Charger; ?Instrument Voltage Display; ?LED drive power; ?Test Meter; ?Circuit Test; ?Power Conversion Parameters: Size: 72*58*26mm Working Voltage: DC 5V-30V Output Voltage: DC 0.6V-30V Output Current: 0-4A Output Power: 50W(Max with fan. Default 35W) Work Frequency: 180KHz VoltageDisplay Precision & Resolution: 0.5%; 0.01V Current Display Precision & Resolution: 0.8%; 0.001A Conversion Efficiency: About 88% Support Anti-reverse Protection; Anti-backflow Protection; Short Circuit Protection Over-temperature Protection: 100? Working Temperature & Humidity: -20?~100?; 0%-95%RH Note: ?Input undervoltage protection voltage is 4.7V. Module need re-power if input less than 4.7V. ?It’s a DC power module, So it can’t connect to AC power. ?Connect input before connecting battery if used as charge and make sure output voltage is higher than battery voltage. ?’VIN-’ and ‘OUT-’ can’t be connected together, or it can’t support constant current output. ?Ensure input voltage greater than 8V in order to output maximum power. It just can output about 15W when input 5V. ?Make sure input power is higher than load power. ?Step down output power if module is hot.
