400W 80V 40A  Dual Channel Adjustable LCD DC Electronic Load 220V


                        
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.
