Default Magma Dyno-Charge

Do any of you guys have one of these chargers? I was wondering what size power supply it would need.

Thanks Neil.

Should have mine early next week Neil. I would have at least a 10A. Really any of the RC PS's should get you taken care of.

Somehow it seems related to the Trinity and the Much-more unit.

I just got mine!

What can I say from first impressions:

Very easy menu I didn't need the instructions.
5 charge profiles that can be renamed and all adjusted
Saves your dyno runs for review after
Shows charged capacity and real times
Shows Max amp draw at which Volts and RPM
Shows Max RPM at which Amp draw and Volts

Very nice real backlight white lettering on Blue
Nice charge clips for power supply and battery

Comes with Motor stand and Temp prob.

So far so good, the charger for the price is the best in its class.

Related to Trinity and muchmore?
Trinity does'nt charge batteries and niether does the muchmore.

The box is also mint only thing is no foam in the box or the charger to sit in. Very light and nice black case.

Get one if you are looking for a new charger.

you wil need a power supply rated as high as the maximum amp draw allowed by the charger...

so if it pulls 8 amps for charge u need 8 amps..

but if the motor run feature pulls up to 12 apms, then u need at least 12 amps.. i wuld recomened, at least 3 amps higher then the allowed for the motor run.. this way if it spikes (momentary higher amp draw) then it will be safe..

all the other features on the power supply dont pull enough power to riase amp draw.. there voltage based numbers..

Actually, some of the new chargers uses a technology called PWM which uses power much more efficiently. Say if you're charging a battery (say around 9V when full) less than your power supply voltage (say 13.8V) at 5amps. The charger will actually draw about 4 - 4.5amps.

So if you plan on charging a 7.2V pack at a maximum of 8amps then a power supply of 8 or more amps will be more than enough.

For older technology the charger actually dissapates the excess votlage as heat so it's less efficient. In that case then you would require a power supply with output more than 9-10 amp to charge any pack at 8amps.

I believe the APS Dyno-Charge is one of the newer chargers to use the PWM technology. That's why it's so lightweight and compact and it doesn't require a fan to keep it cool.

I just got mine a yesterday!! It works great and it looks even better!!!

I heard this Dyno charger is designed by a local Canadian racer. If you guys have any question about this charger, you can post your questions in the www.torontorc.com forum.

I just purchased one and I think it's awesome. It has a very interesting "pulse" break in, and it comes with a motor stand for dynoing the motors and then a seperate temp probe that you can plug in too. It's sweet. Charges good too, good punch and I got more runtime than my pulsar.

A 25 amp suply will do fine. I run the dyno charge and a turbo off it with no problems.

I personally think its much nicer then the trinity, the ability to charge puts it a big step up. If only it had a nice high discharge capability, that would put it way up in the ranks.

You are correct ... this charger was developed by one of the guys that race at this club ... smart guy and a serious racer. I am sure that if you post your questions there, you should be able to get some help.
