Features:
This product is a direct current CNC electronic load, with a maximum power of 150W and a maximum load current of 20A
2.4-inch TFT color screen, with cumulative running time, core temperature with load, sensor monitoring temperature, 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
The 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, 9 levels of screen brightness adjustment, standby time setting, and restoration of factory settings
The product works with a 12.0V1A independent power supply 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 analog electronic loads, it adopts protects first and then work mode to control the discharge, which can effectively protect the discharge power supply from damage caused by over-limit and over-discharge.
It adopts a four-wire wiring method, and 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
