Filter Specification
The EMC mains filters available for the SJ300 have been specifically developed for the Hitachi Range of Inverters, enabling systems incorporating them to meet the European EMC emission standards for domestic and industrial use.

Input/Output Reactors
Input Reactors should be fitted where the supply is susceptible to power line disturbances or where supply harmonics need to be reduced. It is common to fit Input Reactors as standard on Inverters over 30kW. Output Reactors should be fitted where the cabling between the Inverter and the Motor exceeds 50 metres.
