Maintain impressed current for cathodic protection, even if the interrupter loses power
Our normally closed solid-state relays are small enough to be mounted inside most rectifier cabines and, compared to mercury relays, they:
- Operate with a lower control current
- Have faster cycle times
- Last longer
Plus, our DC solid-state relays include a unique transient voltage suppression (TVS) technology custom-designed by engineers at American Innovations. This new TVS technology absorbs the inductive energy released during on/off switching and allows the relay to switch much higher currents than previously available.
