Our innovative, reliable surge protection solutions help reduce costly downtime by protecting sensitive electrical and electronic equipment against the damaging effects of transients.
Coil surge suppression, reverse polarity protection and leakage
At what level of current will the relay coil begin to turn on or be energized? The relay socket in all the 700-HL relay assemblies provides a diode suppression circuit for the operating coil
Surge current protection for relay output
If it''s a switched mode supply, inrush current of the input filter capacitor is most likely causing contact welding. A NTC current limiter can possibly help, but using an oversized relay or
Surge Suppression for a Three-Phase Motor Starter
This engineering brief presents three alternatives for surge suppression in a 24 VDC contactor (relay). It specifically addresses the flyback (back EMF) voltage spike that occurs when a
Current surge protection for relay contacts when closing
So I tried to figure a way to prevent the current spike when the capacitors are empty and the relay is switched on. I finally added a small low-value power resistor in series between the battery
Selecting Surge Suppressors for Relays, Contactors and Starters
Surge Suppressors are used to suppress the high voltage spike that is generated when a relay or contactor coil is de-energized. The electromagnetic field collapsing across the coil generates a
