12V Alternator direct output power Linearisation Device (ALD)

Total alternator control. Certain applications require current and voltage control directly from the alternator’s output - lithium battery charging, for example. This is not straight forward. The problem is that an alternator produces a half wave, non filtered wave form. This is a poor quality output and could not be used directly into any normal equipment without using a battery as a buffer. Failure to do this will destroying the equipment. In addition, lithium batteries require a shut off system so at any time the alternator could become unloaded fast which would destroy the alternator. This is prevented under normal use as an alternator is  always connected to a battery. The battery absorbs all the spikes to make a relatively smooth linear power supply. The battery is crucial to achieving this smoothness and also allows the alternator to be unloaded without destroying the alternator.

The solution. The ALD fits directly onto the alternator’s output. The ALD absorbs the large spikes from the alternator’s generation system and also offers itself as a buffer to absorb the alternator’s power during electrically unfriendly events that occur during lithium charging. This product is essential if alternators are used directly onto Alternator to Battery Charger or Battery to Battery Charger without being attached to a starter battery.

Numerous benefits over a normal 12V starter battery? The ALD is smaller and lighter than a regular starting battery. Batteries also need maintaining, they gas, they may over charge and they do not like being transported - the ALD does not suffer from any of these issues. The ALD also acts as a very prominent alternator protection device, sheltering your alternator from any harmful back spikes.
