$125.00
 
Unit actual rating (the actual device rating) for the Pro Reg D By far the most powerful regulator around due to its fan cooling. Positive field control 25A max field current. Negative field control 30A max field. Real world rating (rule of thumb): 12/24V alternator with standard regulator fitted. Up to approx 600A alternator, more if a negative field control. 400A if stand alone, without existing regulator fitted. Please note advanced regulators are not suitable for some modern vehicles / boats with integrated engine management systems as they increase the alternatorís voltage and this can be interpreted by the management system as a fault on the alternator. Please use an Alternator to Battery Charger or a Battery to Battery charger for these applications.
