The Clover Systems DR340 Dynamo Regulator is an all-electronic voltage and current regulator for DC generators. It is an exact, drop-in replacement for Lucas RB340 regulator. You can replace your old unreliable mechanical RB340 without any mounting or wiring changes, or adjustments.
Replacing the old mechanical regulator saves a lot of time & grief filing relay contacts, adjusting voltage, current, & cut-out.
Protect your investment with the latest state-of-the-art technology. Avoid an inconvenient dead battery, and get consistent performance.

The Clover DR340 Dynamo Regulator is designed as a direct replacement for Lucas RB340, and will work with all Lucas dynamos. It will also work with Autolite, Bosch, Delco, Ford, and many other DC generators.
A complete list of compatible models is too lengthy, so please contact us if you have any questions. Since your generator may not be original, it is helpful if you know the model of your current generator. The regulator will be configured to match your generator, including voltage and current limit. No adjustment is necessary.
