NFC-Т переключатель конденсатор

THE PRODUCT FEATURE The rapid capacitor switching switch of NFC-T series mainly applied to the impact load , it need to quikly switching the electrical load site of the capacitor , such as : welding machine , steel rolling , port suspended , elevator , inverter frequency furnace and other load change site . This capacitor switch has the high following speed , and can be effective compensation the impact load , the response time is 10 20miliseconds , effective saving the energy , it is the irreplaceable product of AC contactor and combination switch . The capacitor switch modual is using high-speed CPU , pulse transformer triggering , it has multiple protection schemes and 20ms fast switching technology , to enssure the trigger modual controlled thyristor is voltage zero-crossing connected , current zero-crossing broken , and do not produce switching surge . Technology parameter Voltage 220V±20% 50Hz Response time ≤20ms Control method Manual control: the passive nodes input(No 3,4 terminal of the machine) Automatic control 12V/DC,10mA(input the No 5,6,7 terminal of the machine) Auxiliary contacts 5A,250V the passive nodes output(the indicator used to control capacitor) Communication interface RS 485 MODBUS protocol 5.
