ZEFTRONICS designs and manufactures the best Voltage Regulators, Alternator and Generator Controllers, Over-Voltage and Parallel Relays and other general aviation (GA) aircraft products. Many of these products are FAA-PMA approved.

As many aircraft mechanics and engineers around the world know from using ZEFTRONICS products to improve system performance and solve electrical charging system (ECS) problems on aircraft, ZEFTRONICS delivers electrical charging system solutions.

*** TESTIMONIALS ***

"A major advantage the Zeftronics regulator has over competing units is that its output is short-circuit protected. What that means is if the field wire chafes and shorts to ground (mine did) or the alternator gets an internal short to ground, it won't destroy the regulator (it trips an electronic fold-back that essentially turns the regulator off until the power is cycled). The (previous) regulator I had in my airplane does not have that protection, and even a very brief short to ground destroys the output transistor in the regulator. I'm not sure the Plane power regulator has output short circuit protection. If it does not, then I wouldn't buy it. Even if it does, the Zeftronics regulators are PMA'd for your airplane and have an excellent track record. Why go with anything else?" Ray N3351W

If you need a regulator get the Zeftronics". Joe@TAN

I also installed the Zeftronics Regulator with built in overvoltage sensor. This box was also very easy to install, with only 2 wires to hook up. My installation was inspected by an A/P on Friday, and he signed off my log book. Both of these items are PMA'd, so only require a log book sign off". Mike H.
