Characteristics: This product is a DC CNC electronic load, with a maximum power of 150W and a maximum load current of 10A. 1,77 inch TFT color screen, with total working time, core temperature with load, real-time voltage, real-time current, real-time power, cumulative capacity, cumulative energy, discharge stop voltage, discharge stop current and load switch status display function. Voltage, current and surge protection values can be set; and discharge stop voltage and discharge time can be set. Multifunctional design, system menu interface supports voltage calibration and current calibration, and supports zeroing of collected data. Active cooling, when the load current 3A or core temperature 40 , will start the fan. Compared with traditional analog electronic loads, it adopts protection mode first, then operating mode to control the discharge, which can effectively protect the discharge power supplies from damage caused by excessive limitation and excessive discharge. It adopts four-wire wiring method, wire voltage drop does not affect the voltage measurement, so that the voltage measurement is more accurate, during wiring it is enough to make a short connection A and V, V- and A- respectively. How to Wire: ① use thick wire to connect the positive power supply terminal to A, negative power supply terminal and connected A-, when connected, the voltage and current display 0. ② Use a thin wire to connect the positive power supply terminal to V and the negative power supply terminal to V-, and the real-time voltage shows the power supply voltage when connected.
