Can I slide on this? 12vdc instead of 11vdc

[David Askari]

I got a JVC camcorder body smx or amx 240 with lcd and 600 zoom. I am
using a minolta camcorder soldered to the battery teminal six they
both are six volts ( if thats bad, tell me also). But dc in is 11
volts and I have a rca camcorder (thoses old vhs ones) that has a 12v
adapter I would like to lose the solder and wires and use it instead.
But there must be a reason for 11vdc which is something new to me.
Obviously this camcorder was bought for less than 50 bucks (hense the
solder job,etc) which I use for remote viewing or these days its known
as servalliance and spying (better keywords for search). I still
don,t want to burn it out though. Now it has a halogon built in
light, and lcd. I wonder if I could get the 12 volt rca to drop to 11
by always having the lcd and light going or just the lcd on bright?
It,s out there but 11volts fudge to 12volts? I afraid to do it. I do
know I could get away if it was a bulb only for a while.

The proper answer would depend on the exact design of your unit. I
would not go with a general answer. This has to do with the way the
voltage regulator circuits are designed.

As a first choice, I would suggest to have the proper power supply to
run your camera. It is possible to drop the voltage output of your 12
Volt power supply unit. If your camera requires less than 1 amp of
current to operate, including the lamp, you can use a 2 amp rectifier
diode in series with the power to the camera. These diodes are
polarity sensitive, and must be wired in the correct way. A single
diode in series will drop the power supply output by about 0.7 Volts.
This should put it close enough to be near to specs, or you can put
tow of them in series to give a bit more safety. I would use a 2 Amp
or greater rated diode with a PIV (peak inverse voltage) rating of
more than 100 Volts as a dropping device.

The frequency response, switching speed, and in dept specs would not
be critical at all for your simple application. You must make sure
that the forward dropping voltage is rated to at least 0.7 Volts or a
bit greater. If the diode you find is rated to about 0.58 or so, you
can put two in series. to get about 1.16 Volts for the drop.

These diodes can generaly be found for less than a dollar or two at
many electronics parts distributors. You may have to purchase a
minimum amount. Just tell the man at the parts counter, you want a
popular type of rectifier diode that is rated with a PIV of 100 Volts
or more, at 2 Amps minimum, with a forward voltage drop of about 0.6
to 0.7 Volts. The forward drop can be tested using most any DVM that
has a diode test range on it. Two of these in series should do your
job very nicely.

Thanks for the response that has some actuall substance to it where I
can use it for a good solution for this issue and future ones. It was
informative enough to explore the area of diodes to further expand
practical knowledge. Sometimes the responses I get here are the same
as I would get at a bar. Or some question that is even more general
than mine to begin with.
