HIGH OUTPUT ALTERNATORS

The 'Alternator Range' consists of high output stand alone marine and heavy duty alternators supplied with a standard machine sensed regulator. The range varies from 35 - 160 Amps @ 14 volts and 75 - 150 Amps @ 28 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.
We have added to our range three alternators with high outputs. The alternators Alt14 & Alt17 are for replacing the existing alternators on Yanmar,Volvo Penta and Vetus M4 engines. The third option is a higher current (70 Amp) output replacement for Lucas A127 55 Amp alternators (as fitted to older marine engines). Clicking on the photos or the Blue highlighted type number in the table below will take you to the information pages. Alt2 (90 Amp) is suitable for replacing standard Valeo 60 Amp alternators fitted to new Nanni engines. Alt17 is available as a high output replacement alternator for Volvo engines but note: the supplied pulley is smaller than the original (76 mm) and will require a new drive belt unless the pulley from the original alternator is used. An additional spacer will also be required during installation details will be found on Alt17 page by clicking on the photo below.
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.
Standard single groove pulleys with o/d's of 65 mm (2.5") or 84 mm (3.3") are available for use with standard belt sizes of 9.5mm (3/8") or 12 mm (1/2"). Dual groove pulleys are fitted for the higher output (> 110A) alternators 84 mm (3.3") or to special order 65 mm (2.5") with either a 9.5 mm (3/8") or 12 mm (1/2") belt. Other pulleys available at extra cost.

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) to see mechanical outline drawing click on the photograph of the alternator. 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 help.

* Indicates new low special price. The price of the Alt17 & Alt14 includes a standard pulley of 65 mm, the Alt16 a standard pulley of 70 mm.
 

12 months warranty from date of sale (subject to fair wear and tear excepted).
The Alt14 & Alt17 come with a 65 mm pulley as standard, Alt16 a 70 mm pulley, other non-standard pulleys can be fitted. Please contact the sales office for availability and cost.
For a small charge we can (where possible) modify the alternator for use with our range of 'X-ALT' intelligent alternator charge controllers.
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.

The prices quoted are UK list prices excluding carriage and VAT.
Contact sales office for carriage charges.
Payment is accepted by cleared cheque or most major credit cards (excluding Diners Int.) Where payment is made by credit card there is an additional £2-50 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.
