What are the different types of Surge Suppressor used in Vamp relays.

Different surge suppressor types:
1) Diode suppressor (Used on DC coil)
o Suppresses the DC voltage by recirculating the voltage through the coil.
The energy will be dissipated by the coil itself.
o Most common surge suppressor on DC coils
o Breaking inductive DC currents without surge suppressor generates
voltage peaks up to kilovolts. Therefore using surge suppressor is highly
recommended.

2) ResistorCapasitor suppressor (Used on AC coil)
o The resistor controls the rate of capacitor charging and to limit the coil’s
inrush current. The capacitor is used to limit the voltage peaks.
- Varistor suppressor (Used on AC and DC coil)
o The varistor limits the voltage peak coming from coils inductive discharging
current.
o Maximum reduction of transient voltage peaks.

3) Bidirectional peak limiting diodes (transil)
o Maximum reduction of transient voltage peaks
