Power supply question

[smurf]

I have one of these protech chargers that I tried using as the source power for my triton charger. It can be seen here http://www.rcgroups.com/forums/attachment.php?attachmentid=611416

When I hook the triton up to the leads where you can check voltage and turn it on, I get a input voltage error. I put my volt meter on at the same time and it shows over 15vdc. Input for the trito needs to be between 10.5 and 15 vdc. If I put a battery on the connector where you charge from the protech it will show the voltage from the battery plus any extra input. It is designed to charger 6 or 7 cell nicd batteries.
What I'm wondering is if there is a way I can use this as my power supply and not have it go over 15vdc or under 10.5vdc?

thanks

You can't use a charger as a power supply unless it is listed to act like one (the Duratrax ICE can, for example). If you were to tap into your charger, you may be able to find the circuit that turns the input AC voltage into something like 12v for the charger to use. If you can find this, then you can use the charger as a power supply. Or, you could just get a cheap power supply:

This person is using it for a power supply for his setup. http://www.rcgroups.com/forums/showthread.php?p=4419950#post4419950 If it has over 15vdc coming off the leads, then why couldn't it be used?

I found out from this person that it has a current adjustment knob on it, something mine doesn't. Anyone know of a way I can get the dc voltage down just below 15v so the triton charger will work with it? I know there is an electonic guru in here somewhere.

Thanks for looking

Hi, Smurf

One,two or three Silicon power diodes ( even on a heatsink ) in series in the 15v line will drop voltage to match your needs ...

so simple ... ;)

Thanks Alain

What rating of diode?

[dj2u]

as many amps as you want to draw / your charger is able to deliver or a bit more to keep it cool

I don't have a Triton, but just looking at its specs, you'll need either a 12v battery capable of a high current (automotive type) or a 12v power supply capable of handling 10 -15 amps.
