KL series are highly precise economical dual channel DC electronic load, can be widely used in LED drivers, switching power supply, power adapter, mobile power, chargers, batteries and other products, testing and aging. Using potentiometer adjustment method, simple to use, easy to adjust. With constant current, constant voltage (CC, CV) mode, the current mode can be used to simulate a resistive load to discharge the battery pack to power load; their voltage mode can be used to simulate the capacitive load to charge the load, and simulate the LED to the LED drive power constant voltage characteristic load. With perfect protection function, and its performance and functionality is the traditional slide wire resistor can not be compared for the related industries can greatly improve production efficiency and reduce costs.
