200A enforced alternator of Mitsubishi 115A Volvo D1/2/3 etc., does anyone have that?

[CaptainRivet]

Hi all,

I found a 200A Alternator that claims to be the enforced version of the 115A Mitsubishi alternator found on a lot of engines eg Volvo D1/2/3.

They claim made in Germany and direct replacement. Does anyone have that alternator?
It’s just 499Euro and together with a nordkyn VMR regulator for 250Euro would be a very cheap and powerful upgrade avoiding all the problems you have with volvo‘s D+ and large alternators like balmar.
I have that too on my Volvo D2-50F, the 115A delivers 80A for around 20min and then throttles down to 60A on longer runs. If that 200A behaves quite similar you can expect 140A for 15min and around 110A longtermed. For 500Euro a cheap upgrade, especially if you have 2 engines so you can double the charge capacity for just 1000Euros without problems as plug&pray replacement.

What does 'enforced version' mean? Built for marine use?

It appears that alternator is set up to use the standard (single) micro-V belt. That seems like an awful lot of power to be transmitted by a single belt. I would expect upgrading to a 200A alternator would require moving to a two belt setup.

A 200 Amp small case alternator would generate 200 Amps for a very short period of time before it overheats. No matter how "enforced" it might be...

Did you read what i wrote?
I excepted shortterm 140A, and around 100-110A longtherm from the 200A upgrade alternator IF it has the same temp regulation build in then the 115A.
Clear that it won’t deliver 200A but 50%=100A is typical what these small case ones can physically do max.

The 115A Mitsubishi has a quite sufficient and conservative temp regulation which allows for 80A for 20min and then delivers 60A constant without overheating if you have ok ventilation, which I do have.
What’s enforced I don’t know.

Question was does have someone this alternator and can confirm it has the same temp regulation as the 115A and how does it perform?

That 200A alt should deliver around 100-110A which is ok due to balmar for a single micro V3/8, on the upper limit but ok. It’s a direct replacement for the 115A one so set up for the same belt system. But if that’s the only issue happy to go to a 2 belt system or reducing output to 90A if that runs well with 1 belt.
Heavily overpowered on the engine side (doing 15kn at WOT on a Lavezzi), 2x50hp instead 2x20 so loosing some hp I don’t care.

Based on what I see in the link

Three comments:

1. The pully looks to be made for a wide belt, not a small v-belt. Am I wrong about this?
2. The alternartor has internal regulation, not compatible with external regulators
3. What are the dimensions?

This sounds very interesting.
The standard 115A alternators (on 2 x D2-50) are very frustrating in the tiny output they get reduced to. OK for long motoring, but hardly worth using if just trying to charge batteries when on anchor.
I am currently getting a Mark Grasser 250A alternator system built (hopefully! - it has taken several months so far)

What does that mark grasses system cost all in? Heard around 3k all in…And then you have it just on 1 engine…
Yep that’s interesting as 2x100A is quite ok and both on anchor on for 30min would give you 100AH…so after Anker set just leave them a bit more running.
As emergency charge when bad weather for 3 days in row it’s ok.
Have new 2xd2-50 and therefor alternators are new. Just looking to improve with reasonable costs and taken into account solar is no1 charge source.
At the moment I have 2x 30A DC-to-DC charger that maxing one 115A alt out with 65A draw, that’s what I do when motorsailing or motoring, running 1 engine. A Citrix is combining both FLA starter so doesn‘t matter which ones run, the 2x30A chargers work. 2 only on for maneuver or heavy weather. Doesn’t make sense to have a regulated alternator.

The Nordkyn VMR200 regulates the original 115A Mitsubishi via its sensor cable and also measures and limits output without modifying the alternator.

To be able to do that, the alternator must have the internal temp regulation of the original 115A Mitsubishi. Many aftermarket ones leave that away…question is if that is the case here to or if it has it. Obviously the enforced 200A is not an original Mitsubishi but claimed to be high quality „Made in Germany“.
Asked the distributed, let’s see what he answers.

Another alternative would be to have 2x115A on one engine and regulate them with one nordkyn VMR200.
Problem with that is that the bracket from Volvo costs 1400$ for that piece of metal…unbelievable…is there a supplier that delivers that for reasonable cost of around 200-300Euro?
An overhauled original 115A is 180Euro at the moment.
