Brand new RMSTATOR Red Machined Aluminum Mosfet Regulator

Our new RMSTATOR machined aluminum Mosfet voltage regulator is a great upgrade for heat dissipation in any powersports charging system. After 10 minutes of use, our billet aluminum heatsink runs cooler by 33% than standard cast regulator housings. Our new RMSTATOR red regulator, equipped with the renowned Mosfet regulation technology, is an added value to any three- phase permanent magnet charging system.


It is time to update or replace your voltage regulator with the advanced MOSFET type.

It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up, it will simply turn off for a while and cool off.

  • The quality exceeds the OEM equipment
  • Improved heat sink and charging capabilities
  • Higher grade of electric components

Why use Mosfet Enhanced technology?

  • Runs cooler: Runs much cooler than the traditional Shunt voltage regulator rectifier.
  • Saves gas: Less load on the stator, less work, less fuel is used and you save.
  • Regulated energy: The power charging your battery is steadier and smooth.
  • Extended battery life: Extends the battery’s life and cold cranking capacity.
  • More engine power: Removes stator load resulting in more engine power.
  • Optimized power: Optimize power delivery by switching the stator coils on or off.

With Enhanced Technology Design

This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.
