Features: 2.4-inch TFT- color screen, maximum power 150W, maximum bearing- current 20A. With constant current, constant voltage, constant- power and constant resistance. Can set voltage, current, power over limit for protection; Set the stop- discharge voltage and discharge for time; Measure the power supply temperature through an external NTC- sensor. Use 12V/1A independent power supply, equipped with alloy integration silent (20±3dBA) radiator, intelligent temperature control system to control the radiator fan work. Using four-wire wiring method, voltage measurement is not affected- by the wire voltage drop, so that the voltage measurement is more accurate.
