Measuring Control Function

(1)Load control: Load any current value within the rated value, measure and display the voltage and current parameters of each circuit.
(2)Manual control: The load is equipped with a local control panel and is divided into several power gears that can be loaded by switch control. 
(3)Control pattern interlock: There is control pattern switch, when choose one control pattern, operation of the other pattern is invalid, avoid the clash.

Protection

(1)Emergency stop: User can press Emergency Stop switch in panel, when the load bank is locked in this state, it can't add any load. 
(2)Overvoltage protection: When input voltage is over the safety value, it will unload automatically and give an alarm.
(3)Short circuit protection: Fuse could avoids damage to equipment when short circuit or current overload.
(4)Overheating protection: When temperature is over the safety threshold, it will unload automatically and give an alarm.
(5)Fan interlock protection: Load bank can't add any load before working power on.
(6)Protection Buttons: There are buttons for some protection, when misinformation occurs or user has special needs, user can temporarily turn off the corresponding protection function.
(7)Chassis Ground Protection: in order to avoid the danger of electric shock when operating, the load bank is equipped with special ground protection termi

Thanks for use Multi-circuit AC/DC Load Bank. According to the special requirements of the user's use site, this agreement proposes the technical standards of the functions, performance, usage, structure, installation and test of Multi-circuit AC/DC Load Bank (hereinafter referred to as load bank), which is an efficient and reliable choice for client to meet the needs of the generator set.
