Load box LP-3
Product overview:
This load box is designed and manufactured according to IEC60884,IEC61058,IEC606691 standards and etc. It is used for the on-off ability test and the normal operation lifespan test of the Switches for household and similar fixed-electrical installations. Besides, it is also applied in the test of breaking volume of plug and socket, and mechanical action of normal operation lifespan.
This device is with blue framework and gray cover. The top of this apparatus is the operation control panel on which there are switches for controlling power supply, for the electric capacity conversion and for the load type conversion. There are also the displaying meters of connecting current and voltage as well as power, the buttons of start and stop, alarm, the status indicator light and so on. Below are the according knobs for output voltage adjustment, for current adjustment and for inductance adjustment. There are three load lines. Each of them has the function of resistive, inductive and capacitive Load test. The kind of load test can be chosen by the transferring switch. The load box inside is cooled by the strong wind convection. There are terminals below the load box through which the load box can be connected with the switch and plug-socket endurance tester using the wire. During the process of test, the equipment outputs the current and voltage as well as power.
Shanghai kerang technology co., ltd is located in Shanghai City, China, and was established in 2018.It is a company specializing in the field of automation technology: technology development, technology transfer, technical consultation and technical service; installation, design, commissioning and maintenance of automation equipment; and other high-tech enterprises.
