Solder lug terminals with insulator cup
Commutation / Snubber Type SCR and SNU Ceramic insulated screw terminals Solder lug terminals with insulator cup Metal case with Non ferrous covers optional Aluminum Case Type SCR Type SNU
19
Commutating Capacitors
Commutating in layman terms Is a reduction in severity of a punishment by law. Commutating in electrical terms A reversal of current direction or the conversion of alternating current to unidirectional current The cap takes the heat off the SCR
20
Type SCR and SNU Comparison
* This rating only, all the rest are 60 A
21
Type SCR and SNU Threaded studs on the SCR give the higher current rating The SNU aluminum case is ideal for welding applications where current flowing thru the capacitor creates a magnetic field that heats ferrous materials
22
Type SCR and SNU Markets Applications Power Conversion Welders
Power Supplies
