AC400V-250KVA Dummy Load Bank In Good Performance And Resistive Inductive
Introduction
1 AC400V-250KVA Dummy Load Bank can simulate the real working conditions and provides a rigorous test regime for power supplies from 1kW to 60MW. Resistive, inductive(reactive),capacitive or combined load banks can be customised for any application. They can be used for testing numerous sets in a workshop environment, or used for on-site commissioning, witness tests and proof trials.
2 Tailor-made load banks can be supplied for most powers, voltages, frequencies and sizes. Multi-voltage load banks are also available for operation over a large voltage range. At the same time, It can operate in parallel with more than two units.
Application
AC400V-250KVA Dummy Load Bank can be used in a wide variety of applications , such as
Periodic excercising of stand-by engine generator sets
Ups system testing,Battery system testing , Load optimization in prime power applications
Factory testing of turbines , Factory testing of engine generator sets,To reduce wet stacking problems ,

Main features
Fan Delivery Protection: insufficient air volume with any fan 2450m³/h, system unload automatically and give an alarm.
Overload protection with fan: when any fan cannot normally work, the load bank can 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.
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.
