What is the purpose of a surge protector in an irrigation controller?

A surge protector is an essential component in an irrigation controller system, specifically designed to safeguard the electronic equipment from voltage spikes that can occur due to lightning strikes, power surges, or other unexpected electrical disturbances. These spikes can cause significant damage to the controller and related components, potentially leading to system failures and costly repairs. By absorbing or redirecting excess voltage away from sensitive electrical components, the surge protector ensures that the irrigation controller operates reliably and has a longer lifespan.

Understanding the role of a surge protector highlights its importance in maintaining the integrity of the irrigation system and preventing disruptions in operation due to electrical issues.
