We currently have a few of these Sterling Power
external voltage regulators at a this special price. These units are brand new, never opened and are current production.
NOTE: These regulators make an excellent "spare/emergency" regulator at decent price. Please be aware that these regulators have no way to limit alternator current to match your belts capabilities or to prevent an alternator from bouncing off high-temp continually. When alternator temp is exceeded this regulator bounces between 100% and 0% and many customers complain about this. While it is an exxternal regulator it is not one we typically recommend as your primary regulator.
For a much more advanced "budget level regulator" please consider the Wakespeed WS100
Sterling Power ProReg-D Advanced Alternator Regulator
- Sterling Power Advanced Alternator Regulators allow
you to change the standard output of your alternator into a four step
- 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.

have to buy a new alternator as part of the installation. No pulley
changing, no new bracket building.
- Four different battery charging profiles are selectable: Open lead acid, closed lead acid, AGM and GEL.
- Will work with both positive or negative field alternators (P-Type or N-Type)
- Includes a battery temperature sensor to provide battery temperature compensation.
- Includes an Alternator Temperature sensor to monitor the alternators temperature.
- The ProReg-D has an optional remote that you can purchase as an option.
