Sterling power ProReg-D 12 Volt / 24 Volt Advanced Alternator Regulator

Sterling Power Advanced Alternator Regulators allow you to change the standard output of your alternator into a four step charge profile.

Our Four Step Battery Charging Profile extends the life of your batteries by fully charging and conditioning your batteries, as well as entering a float mode when charging is complete to protect against overcharging your batteries.

Advanced 4 step charging algorithm provides a charging rate that recovers your batteries up to five times faster than from a standard alternator.

12 or 24 volt capability from the Pro Reg-D Advanced Alternator Regulator.

Unlike other Advanced Regulator packages on the market our advanced regulators will work with your existing engine alternator. You don’t have to buy a new alternator as part of the installation. No pulley changing, no new bracket building.

When installed in conjunction with our ProSplit-R Zero Drop Battery Isolator Product Line, you can provide advanced 4 step charging to all of your battery banks from your alternator, without the risk of any one of your battery banks discharging the others.

Four different battery charging profiles are selectable: Open lead acid, closed lead acid, AGM and GEL.

Will work with 12 volt system and positive or negative field inputs.

Includes a battery temperature sensor to provide battery temperature compensation.

Includes an Alternator Temperature sensor to monitor the alternators temperature.

The ProReg-D model has an optional remote that you may purchase from our store.
