After a couple months of these not being available, they are now back in production.

This field flashing module (Auto Build-Up Relay / voltage build up module) is used when a generator will not build up voltage because of low residual AC voltage. Most regulators will not "turn on" unless they see at least 5 volts residual. This is a common issue on brush type machines. Often needed on static regulated machines using our VRSE30HW or VRSE50HW.

Includes appropriate resistors, relay, & adjustable timer circuit all in one compact module.


Works on 12V or 24V generator battery systems. Instructions included.

There are currently no product reviews.
