1.Constant current and constant voltage design, this boost converter has DC9-60V input and DC10-120V output voltage, 85% high conversion efficiency and with the max current of 15A. 2.1.77 inch TFT digital display screen, clearly displays real-time output voltage, real-time output current, real-time output power, trigger mode, input voltage, etc.When the input is turned on, the output end has power output all the time, and the voltage is equal to the real-time output voltage displayed in the interface. 3.Two kinds of power-on program trigger modes design, AUTO mode: power-on boosting program runs automatically; power-on boosting program does not run; long press "SET" button for 6 seconds to switch the trigger mode. 4.Multi-parameter setting, support voltage setting, current setting, data group setting, double click "SET" button to enter parameter setting mode. 5.Support call the data group, click "+"or "-"to switch data group, only call, not starts boost.Starts/Stop running the boosting program, click "ok"button in OFF state to run the program, the output voltage will rise to the set voltage. Click "ok" to stop the program in the ON state, and the output voltage will drop to the input voltage. Input voltage (U-IN): DC9V-60V Input current: 0-15A Output voltage (U-OUT): 10V-120V Output current: 0-15A Conversion efficiency:85% Operating frequency: 150KHZ Short circuit protection: 20A fuse (non-self-recovery) Operating temperature: -40-85 Heat dissipation mode: active heat dissipation, connected to the input fan continuous operation Voltage adjustment display: 009.0V-120.0V Current adjustment display: 00.01A-15.00A Output ripple: less than equal 50mV Storage group: 10 groups Standby power consumption: less than 150mA (measured when input 12 V) Colour:green Material:plastic Package Contents: 1 x Current Constant Voltage Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
