The AutoMeter electronic snubber is a noise filter engineered for Spek-Pro tachometers to limit voltage spikes and protect delicate electronics. It provides over-voltage protection against automotive load-dump events and filters negative EMF spikes from inductive loads such as starter solenoids and fan motors, clamping voltages above +16 VDC and grounding negative transients to safeguard instrument signals.
