Shelly RC Snubber - Energy Absorbing Circuit

Description

SHELLY RC Snubber

The RC Snubber is a component that comprises a resistor (R) and a capacitor (C) connected in series. It effectively mitigates voltage spikes that can occur during the switching of inductive loads by providing a short-term alternative current path around the switching device, so that the inductive load is safely discharged. The RC Snubber can protect sensitive components of your Shelly device from voltage spikes and improve the overall performance and reliability of the connected circuits.

Main applications:

The RC Snubber finds common applications with inductive loads, such as:

• Fans

• Refrigerators

• Air-conditioners

• Washing machines

• Tumble dryers

• Transformers

• LED light drivers

• Other devices with electrical motors

You should connect RC Snubbers in parallel to inductive loads which you intend to switch with Shelly devices. Connect the RC Snubber as close to the inductive load as possible.
