Features: _x000D_ This is a non-isolated DC power converter module with long service life. _x000D_ High power and stable output, it converts 10-32VDC to 12-60VDC. _x000D_ High quality components ensures high conversion efficiency, up to 95%. _x000D_ Designed with large heat sinks for better heat dissipation. _x000D_ Widely use for solar power voltage stabilization charging, battery pack charging, large power LED driving, etc._x000D_ _x000D_ _x000D_ Specification: _x000D_ Type: Non-isolated step up module (BOOST) _x000D_ Input Voltage: 10~32VDC _x000D_ Input Current: 16A (MAX.); if more than 8A, please enhance heat dissipation _x000D_ Quiescent Current: 15mA(tested when converting 12V to 20V; it will increase when output voltage is higher)_x000D_ Output Voltage: 10~60VDC continuously adjustable_x000D_ (Applies only to where the input voltage is less than the output voltage, can not step down voltage)_x000D_ 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)_x000D_ Constant Current Output Range: 0.3~8A_x000D_ Turn Lights Adjusting Range: 0.3~8A_x000D_ Output Power: Natural cooling 90WMAX; Enhanced cooling 150WMAX_x000D_ Operating Temperature: -40 to 85(if temperature is too high, please enhance heat dissipation)_x000D_ Frequency: 150KHz_x000D_ Conversion Efficiency: 95% (Efficiency is related to input/output voltage, current and voltage difference)_x000D_ Short Circuit Protection: Yes (input 15A fuse)_x000D_ Reverse Input Protection: No, usually can connect diode in series to the input_x000D_ Output Indicator Light: With charging indication; it shows red when charging, green when fully charged_x000D_ Output Flow Back Protection: Yes_x000D_ Installation Method: Four 3mm screws (NOT included)_x000D_ Wiring Method: Terminal blocks_x000D_ Weight: 74g / 2.6oz (approx.)_x000D_ _x000D_ _x000D_ Package list: _x000D_ 1 * Voltage Converter _x000D_ _x000D_ _x000D_ Current Adjustment:_x000D_ 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_x000D_ 2, The module output current value is set to minimum (rotate counterclockwise CC potentiometer till you hear small crack sound from the potentiometer)_x000D_ 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._x000D_ Because the more battery power, the smaller charging current. Note that current of this module cannot be adjusted with short circuit._x000D_ 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.
