HIGH OUTPUT ALTERNATORS

Click on any of the buttons for further information.
Last updated 28/02/2013

Our range of 'Alternators' consists of high output stand alone marine and heavy duty alternators supplied with a standard machine sensed regulator. The range varies from 35 - 160Amps @ 14 volts, 75 - 175Amps @ 28 volts and 90Amps @ 48 volts . A number of the alternators are battery sensed energized and will require some form of voltage energisation feedback if used with isolating split charge controllers such as our X-SPLIT and the high power X-PORT. Our X-SPLIT and the high power X-PORT have been designed with a battery energisation sense circuit for use with alternators of this type. If you do not understand what a "battery sensed" alternator is click on the "FAQ" button above and see question 8 and the answer. A useful addition to our range is a high current (90 Amp) output listed Alt20 as a replacement for the standard Lucas\Magnetti Marelli A127 55 Amp series of alternators (as fitted to older marine engines).
There is an alternator rated at 48 volts 90 Amp which is becoming very popular for hybrid boats and vehicles but will require a special X-Alt Buccaneer if the alternator is to be used for battery charging.
Alt.2 (90 Amp) is suitable for replacing standard Valeo 60 Amp alternators fitted to the older style Nanni engines. Alternator 1a though only 37A it is a suitable replacement alternator for the smaller older BUKH engines.

Please take notice of the caution information on the relevant pages.

Key Benefits of the Alternators

On certain models there is a facility for manually adjusting the output charge voltage (within limits) to suit various types of batteries and charging needs.
Isolated negative return on most units.
Most alternators can be easily modified to work with our 'X-ALT' range of intelligent alternator charge controllers.
Various mounting options available.
Alt.16 comes with a standard 65mm (2.5") diameter pulley suiutable for a 9.5mm drive belt.
Alt.20 & Alt.21 comes with a standard 80mm diameter pulley suitable for a 12mm drive belt.
All other alternators are sold without a pulley.
For alternators supplied without a pulley, standard single vee groove pulleys with o/d's of 65mm (2.5") or 84mm (3.3") are available for use with standard belt sizes of 9.5mm (3/8") or 12mm (1/2"). Dual vee groove pulleys are required for the 12 volt high output (> 110A) and for the majority of 24 volt alternators, standard pulleys are as follows, 84mm (3.3") o/d or to special order 65mm (2.5") with either a 9.5mm (3/8") or 12mm (1/2") belt.
Cost of modification to alternator to work with our alternator charge controller 15.00 (excl. vat)

The photos show the most popular alternators in our range with compatible engine mounting suggestions (the alternators can also be used whenever the mounting arrangement is suitable).
The complete range of alternators is extensive and we cannot show all available models, if you have a specific requirement contact the Technical Sales department, we may be able to advise on a suitable unit.

12 months warranty from date of sale (subject to fair wear and tear excepted).
A number of the alternators listed above are battery sensed and if a split charge device is used a isolated ignition feed maybe required to energize the alternator, our range of low loss split charge devices (X-SPLIT) have an extra circuit built in to provide this facility.
If you are uprating your alternator ensure that your charging cables are suitable for any increase in charging current that might occur.If you require charging cables with increased capacity complete with suitable copper tubed crimps contact us for a quote. We will need the lengths, expected capacity and terminal sizes.

The prices quoted are UK list prices excluding carriage and VAT.
Contact sales office for carriage charges.
Payment is accepted by most major credit / debit cards (excluding Diners Int & American Express.) for which there is an additional £3-00 administration charge.

To obtain the highest charging efficiency performance from the Alternators we recommend our low loss X-SPLIT Battery Sensed split charger series is fitted to eliminate all unnecessary losses if used on a multi-battery installation.
