Mastervolt 75A Chargemaster PLUS (12v/75A - 3)
Mastervolt Chargemaster PLUS 12/75-3
Chargemaster plus is the next generation of battery chargers that integrates multiple functions into one single device. Replacing auxiliary chargers, battery isolators and VSR (voltage sensitive relay), Chargemaster plus reduces system complexity and cost. Designed for versatility, it charges virtually any combination of three batteries in a fast and safe way anywhere in the world.
- It can handle worldwide AC voltages and frequencies, so if you are lucky enough to be using your boat in multiple countries then this unit takes the worry out of shore hook-up.
- The charging output is split as needed across up-to three separate batteries or battery banks.
- When underway the output from the alternator can be put back through the Chargemaster and distributed to all three battery banks........hence turning your alternator into a three-step-plus smart battery charger.
- With one unit to take care of both shore power charging and alternator charging distribution then you have one capable unit rather than multiple units
- Multicharger with two outputs, one input/output, DC-DC converter, current limiter and VSR
- Combine Lithium Ion, Gel, AGM or Wet lead-acid, and large or small battery banks all with one charger
- 80-275V AC input at 35-70HZ
- Compact, easy to connect and install
- Battery temperature sensor included
- Revival mode: automatically revives even fully depleted batteries
- Priority Charge: sends available power to the lowest battery for faster charging
- Smart input: charge all three batteries from one single alternator for continuous charging on the go
The common sense bit....
So aside from all the jargon, what does this thing actually do?. We firstly it is a battery charger, so it takes a mains input from a shoreline or generator, converts it to 12v and can then use that to charge up to three separate batteries (or battery banks). The new part is that the third output is called the smart-output, this can also act as an input from an alternator. Basically the smart-output is connected to the starter battery, then when the mains power is disconnected and the engine is running it will recognise that the starter is being charged by the alternator; then it will accept the alternator charge current (limited to a maximum of 40A allowed through) and use it to charge the other batteries (or battery banks). So in effect it takes the relatively unsophisticated output from your alternator and then splits it and uses is to charge your batteries using its sophisticated three-stage-plus charge cycle.
