News Flash! We can now have these boards repaired in many cases!  We recommend sending us a photo of front & back sides before sending it in.

These are no longer in production, but we may have a few left, if stock shown above. Please check with us first to confirm, as they are scarce. 

We can have these rebuilt about 75% of the time based on condition, or there is a new improved retrofit kit.

Fits 220 - 240 Volt Single Phase or 120/208 volt 3 Phase Dynagen Vigilant VTS and Milbank Vigilant series auto transfer switches.  

IMPORTANT:  Be sure the jumper is set for the correct battery voltage on generator!  These can be used on 12V or 24V systems (Generator starting battery).
