NFC-402 dc-Schalter Lastschalter

NFC-400 series switches dc load switch mainly applied to the impact load , it need to quikly switching the electrical load siteS and NFC-402 mechatronics complex switch is a intelligent low-voltage capacitor switching switch , it merges the advantages of silicon control and AC contactor , There is neither exist electric arc by electromagnetic relays produced , nor power dissipation and harmonic pollution as long term work of the non-contact switch , the principle of operation is merged the silicon control and the relay , so complex switch with thyristor switching transient zero-crossing switching , connected with acontact in the normal period of the advangages of reactive power consumption , and made up for SCR and AC contactor in the low-voltage reactive power compensation applications deficiencies . The main advantage of this product is : when receiving an external control signal , it from intelligent judgment , Automatically find the best switching point , wavelet current , it does not sintered when electric shock , small energy consumption , Besides , it has abnormal voltage protection , lack phase protection , component failure protection , operation instructions and other functions .
