Hi, I have a Balcar...
Hi, I have a Balcar professional flash unit that I need help with.
I'm only getting about 48 VDC to the discharge capacitors and I need to know how to test the AC AD converter circuit.
Thanks Tony

Hi Tony,

You can test the AC/DC converter circuit using a multimeter set on DC Voltage to test the output from the converter.

Hi Pete, thanks for getting back to me; if I understand I should be getting around 300 V DC to the terminals at the capacitors? If so I'm only getting 48 V DC. Tony
Camera and Video Technician: Pete, Electronic Engineer replied 2 years ago

Hi Tony,

Yes, that is correct. If you are not getting the correct voltage then the converter is faulty and will need to be replaced.

Ok Pete, I suspect the transformer in the voltage converter if I send a picture could you guide me on the input /output leads?
Pretty sure there are no available modules for these anymore.
Thanks
Tony

Maybe that last question needs to be reformulated, is it possible to test and replace the faulty component on the converter?
Camera and Video Technician: Pete, Electronic Engineer replied 2 years ago

Hi Tony,

Finding the faulty component will be difficult, without using schematics and spending a lot of time trying to diagnose which part has failed.

Usually the entire converter is just replaced for a faster, cheaper and more reliable fix.

Except I can't find that part, so I guess it just isn't fixable.
Camera and Video Technician: Pete, Electronic Engineer replied 2 years ago

If you have schematics and some test tools, then you can debug the circuit and find that faulty part.
Or a local electronics repair tech could do it for you.
However the cost for labor to do that repair often exceeds the cost of a new converter, so most people will simply replace it.
Pete.

Thanks Pete, got the tools but I don't have the schematics and I'm in France so there are no electronics stores around here.
Tony
Customer reply replied 2 years ago
I haven't been able to find any parts either, so I guess this just needs to end & stop wasting your time unless you have any other ideas,?
Tony
Camera and Video Technician: Pete, Electronic Engineer replied 2 years ago

Hi Tony,

Without schematics the only other possibility would be to use a similar flash unit to take some voltage readings from and compare.

Pete.
