Features: This is a non-isolated DC power converter module with long service life. High power and stable output, it converts 10-60VDC to 12-97VDC.High quality components ensures high conversion efficiency, up to 97%. Designed with smart temperature control fan, which automatically work when temperature reaches about 60°, and stop when temperature drops below 60°. Widely used for high power solar street lamp driving, various LED lighting CV driving, vehicle-mounted and mobile device power supply, DIY adjustable CV CC power supply, solar power charging, and batteries charging. Conversion Efficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller difference is, the higher efficiency be); Wiring Method: Terminal blocks (Please use large current copper wire)<br><br>Spec: Name: 1500W step up constant current module Type: Non-isolated step-up module (BOOST) Input Voltage: DC10V to 60V Input Current: 10V-30V input voltage, maximum current is 35A-40A; 31-60V input voltage, maximum current is 30A-35A Quiescent Current: 15mA(when convert 12V to 20V, higher output voltage increase quiescent current) Output Voltage: 12-97V continuously adjustable (cannot be used to voltage) Output Current: 22A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current be. please enhance heat dissipation when current is over 15A) Constant Current Range: 0.8-22A(+/-0.3A) Reverse Input Protection: Yes (150A power MOS reverse protection) Input Low Voltage Protection: Yes (10V-50V adjustable, self-recovery) Operating Temperature: -40°to 85°(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Input Over Current Protection: Yes (automatically protect when input is more than 40A, and power supply voltage will not increase) Short Circuit Protection: Yes (
