Features:
This product is a direct current electronic load, with a maximum power of 150W and a maximum load current of 20A. Support test the capacity of power battery.
2.4inch TFT color screen, with voltage, current, power, electricity, capacity, internal resistance, load, operating mode, OVP, OCP, OPP, stop voltage, time limit discharge display function.
It has four working modes design, constant current mode, constant voltage mode, constant power mode and constant resistance mode.
Voltage, current and power overrun protections can be set; stop discharge voltage and discharge time can be set.
Power supplying temperature can be monitored by an external NTC sensor.
Multifunctional design, the system menu interface supports switching between English and Chinese, zeroing of accumulated data, zeroing of voltage and current at no load, voltage calibration and current calibration, standby time setting, and restoration of factory settings.
The product works with a 12.0V1A independent power supplys and is equipped with an integrated silent (20±3dBA) alloy heat sink, with an intelligent temperature control system controlling the work of the heat sink 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, the four-wire system is downward compatible with the two-wire connection method, when wiring, you only need to make the A+ and V+, V- and A- respectively short connection.
