Features: This is a non-isolated DC power converter module with long service life. High power and stable output, it converts 10-32VDC to 12-60VDC. High quality components ensures high conversion efficiency, up to 95 percent . Designed with large heat sinks for better heat dissipation. Widely use for solar power voltage stabilization charging, battery pack charging, large power LED driving, etc. Specification: Type: Non-isolated step up module (BOOST) Input Voltage: 10-32VDC Input Current: 16A (MAX.) if more than 8A, please enhance heat dissipation Quiescent Current: 15mA(tested when converting 12V to 20V it will increase when output voltage is higher) Output Voltage: 10-60VDC continuously adjustable (Applies only to where the input voltage is less than the output voltage, can not step down voltage) Output Current: 8A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 4A) Constant Current Output Range: 0.3-8A Turn Lights Adjusting Range: 0.3-8A Output Power: Natural cooling 90WMAX Enhanced cooling 150WMAX Operating Temperature: -40 to 85(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Conversion Efficiency: 95 percent (Efficiency is related to input/output voltage, current and voltage difference) Short Circuit Protection: Yes (input 15A fuse) Reverse Input Protection: No, usually can connect diode in series to the input Output Indicator Light: With charging indication it shows red when charging, green when fully charged Output Flow Back Protection: Yes Installation Method: Four 3mm screws (NOT included) Wiring Method: Terminal blocks Weight: 74g / 2.6oz (approx.) Package list: 1 x Voltage Converter Current Adjustment: 1, Adjust the CV potentiometer, depending on the load requirements, adjust the output voltage to the appropriate value, example:4 series of battery to 55V, 10 series LED to 37V 2, The module output current value is set to minimum (rotate counterclockwise CC potentiometer till you hear small crack sound from the potentiometer) 3, Connect to ammeter, connected to the LED or battery, adjust the CC potentiometer to the required current. If used for charging, discharge battery before adjustment. Because the more battery power, the smaller charging current. Note that current of this module cannot be adjusted with short circuit. 4, Turn light current adjustment, used to indicate whether the battery is fully charged.Red light is on when charging, green light is on when fully charged. Connect a fully charged battery to output end, and adjust turn light potentiometer till green light is on.
