Features: This product is a direct current CNC electronic load, with a maximum power of 150W and a maximum load current of 10A. 1.77inch TFT color screen, with cumulative running time, core temperature with load, real time voltage, real time current, real time power, cumulative capacity, cumulative energy, stop discharge voltage, stop discharge current, and load switch status indication display function. Voltage, current and power overrun protections values can be set; and the stop discharge voltage and discharge time can be set. Multifunctional design, the system menu interface supports voltage calibration and current calibration, and support zeroing of accumulated data. The product works with a 12.0V1A independent power supplys, with an intelligent temperature control system controlling the work of the heat sink fan. Active cooling, when the load current ≥3A or the core temperature of ≥40 ℃, it will starts the fan. Compared to traditional analogue electronic loads, it adopts protects first and then work mode to control the discharge, which can effectively protects the discharge power supplys from damage caused by over-limit and over-discharge. It adopts four-wire wiring method, the voltage measurement is not affected by the voltage drop of the wire, making the voltage measurement more accurate, when wiring, you only need to make the A+ and V+, V- and A- respectively short connection. How to wiring: ① use thick wire to connect the power supplys positive terminal to A+, the power supplys negative terminal and A- connected, after connection, the voltage and current all displays 0. ② Use a thin wire to connect the positive terminal of the power supplys to V+ and the negative terminal of the power supplys to V-, and the real-time voltage shows the power supplys voltage after connection.
