The Sterling Power PDARW (Pro Reg DW) is an advanced alternator regulator for 12V and 24V boats and vehicles that rely on the engine to recharge a house battery bank. It is waterproof to IP67, ignition protected and fan cooled, which makes it well suited to engine rooms on boats and older RVs and trucks.
A standard alternator is only built to top up a starter battery, so it charges a house bank slowly and never fully. This regulator turns the alternator into a 4-step constant-current charger that adapts each charge to the battery's state, and it can run alongside the original regulator so the factory regulator takes over if the Sterling unit trips. Sterling warns it is not suitable for modern vehicles or boats with integrated engine management; use a battery to battery charger there instead.
Features
- Digital control with soft start to reduce belt slip
- 4-step constant-current charging, recalculated every charge
- Programmable for open lead acid, sealed, gel and AGM batteries
- Works stand-alone or in parallel with the original regulator
- Physically breaks the field wire on a fault so the alternator cannot run away
- Battery temperature sensing with a high-temperature trip at 50 °C
- High battery voltage, high alternator voltage and negative voltage-drop trips
- Alternator temperature monitoring with automatic re-engage once cool
- Protects batteries if the temperature sensor wire breaks or a split-charge relay/diode fails open
- Desulfation cycle for open lead acid batteries
- 13-LED information display
- Positive or negative field control
