Standard alternators are not designed to be good battery chargers; they are designed only to charge an engine start battery sufficiently to start the engine. Because of this inherent design problem associated with the standard regulator, a more advanced regulator is required which in effect converts the alternators from a constant voltage power supply to the latest 4-step constant current battery charger (see battery charger graphs). Because of this improvement in the alternator control system, these regulators dramatically enhance the alternator's charge rates by between 200 – 2000% depending on how poor the original system is.
Sterling Power AR12W - Pro Reg BW waterproof advanced alternator regulator. This product is recommended for alternators lower than 150A rating, for larger refer to the Pro reg D (PDAR)
Sterling Advanced Regulator has full safety features preventing damage to your system. In the event of incorrect installation or a fault developing, the high voltage trip picks up high voltages at the batteries and the alternator and switches off the advanced regulator - discontinued and replaced by Sterling Power Waterproof Digital Advanced 12v Alternator Regulator – AR12W
Digital Advanced Alternator Regulator – PDAR The Pro version offers all the features on the standard digital advanced regulator plus many new ones – the main extra features being the remote control panel, the extra cooling fan for larger alternators and the 12/24 volt capability. - DISCONTINUED REPLACED BY THE PDARW
The new remote control gives active information on the L.C.D. display such as Alternator voltage, Battery voltage, Alternator temperature, Battery temperature, set up details, time remaining on high charge etc. This unit not only displays all the fault conditions but also gives a detailed text scroll on the screen about the faults and what to do. Thus, ensuring on hand information in the case of a problem, even with the advanced regulator being switched off, a voltage display and alarm function is still in operation, making the unit useful at all times. A simple plug in lead ensures simple plug and play operation.
What to expect from an Advanced Regulator. * Maintains maximum performance to alternator’s power curve within preset envelope supplied by battery manufacturers - * Batteries charging 4 – 20 times faster - * Enables 25 – 35% extra useful power to be stored in batteries. A conventional alternator will only charge the battery to a max of about 75% and the battery voltage drops to a useless voltage of about 40%, which means that out of 100 amps of battery capacity only about 35 amps are used. An advanced regulator will fully charge the battery giving an extra 25%, which increases the useful available power by about 70% and MORE....
