Low voltage ride through technology ,Crowbar resistors are applied to the rotor side of wind turbine , installed in the converter system , it can reduce DC-link and low voltage of power network problems，They work under fault conditions . It could dispathch thousand of joules of energy in a very short time.

Small Size , Strong Power and capability of surge current protection Big material constant ( B value ) , Small remain resistance Large steady current , longevity of service ,high reliability.

Aluminum crust surface with good performance in heat radiation , suitable for cooling plate installation can be used in the atrocious environment. Small size , high power load .high insulating capacity , encapsulation by non-flame inorganic material , good performance in vibration . Multi Connection form will be easily to fix Widely used in power supply , transducer , Elevator , Arena audio and high requirement Equipment industry，Resistance tolerance  :  ±1% ， ±5% ，±10% .
