WebApr 21, 2024 · Typically relay drivers are clamped at 40V, and injectors/actuators at 70V. The result is a clean, fast turn-off of the injector or relay, with little risk of the driver being damaged by over-voltage if the inductance is higher than expected or from a snubber capacitor degrading. This clamped driver approach works best with low voltage DC. WebOct 25, 2012 · On relay switch-off, the flyback diode decays the magnetic field of the coil far more slowly than if there was no flyback diode protection present. This causes the relay to take longer for the "clapper type" relay contacts to open. When relay contacts open, small "microwelds" occurs at the contact interface.
