Main features
Smoke Fog Protection: If there is smoke fog in the container, system cut off load automatically and give an alarm.
Fan Delivery Protection: insufficient air volume with any fan 2450m³/h, system unload automatically and give an alarm.
Fan Delivery Protection: insufficient air volume with any fan 2450m³/h, system unload automatically and give an alarm.
Emergency Stop: manually press the Emergency Stop switch on the panel, then load bank is in locked state, and cannot do any operation.
Protection Switch: some protection with switch, when misinformation or in special need, user can close the corresponding protection function temporarily.
Safety Monitor: through indicator lights on main interface, user can monitor system state. When system abnormally stop and protect, software interface prompt the cause immediately.
Overvoltage Protection: the input load voltage is over the safe threshold value, system unload automatically and give an alarm.
Short Circuit Protection and Over Current Protection: when short circuit, fuses in the load bank can insure to unload automatically.
Overheating Protection: temperature is over the safe threshold value, system unload automatically and give an alarm.
