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 ensure high conversion efficiency, up to 97%. Designed with smart temperature control fan, which will automatically operate when temperature reaches about 60C, and stop when temperature drops below 60C. 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 various battery charging. Conversion Efficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller the difference, the higher the efficiency). Wiring Method: Terminal blocks (Please use large current copper wire). Spec: Name: 1500W step up constant current module Type: Non-isolated step-up module (BOOST) Input Voltage: DC 10V 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 converting 12V to 20V, higher output voltage will increase quiescent current) Output Voltage: 12-97V continuously adjustable (cannot be used to step down voltage) Output Current: 22A (dependent on input and output voltage difference; the greater the voltage difference, the smaller the output current. Please enhance heat dissipation when current exceeds 15A) Constant Current Range: 0.8A-22A Reverse Input Protection: Yes (150A power MOS reverse protection) Input Low Voltage Protection: Yes (10V-50V adjustable, self-recovery) Operating Temperature: -40C to 85C (if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Input Over Current Protection: Yes (automatically protects when input exceeds 40A, and power supply voltage will not increase) Short Circuit Protection: Yes
