VOLTAGE
PROTECTED SYNC CORDS
Is
your strobe safe to be used
with your new digital camera
?
Digital cameras have circuits very
sensitive to high voltage and strong current.

The damaging
effects of voltage from the flash can burn out your digital
camera.
Digital
cameras and voltage
High voltage can damage a cameras electronic circuitry.
The electronic, voltage reducing, circuit built into the
Paramount Voltage Protected Sync cord.protects your camera. The voltage limiting circuit has been strategically placed close
to the camera for optimum performance and reliability. The circuit
lowers flash sync voltage to a safe 6 volts.


High sync
voltage is any voltage in excess of the 6 volts recommended by
camera manufacturers. The voltage level determines the intensity
of this spark. Sync voltages around 20 or 30 volts DC are not
immediately dangerous; but can over time damage the camera's
X-sync contact. Many older non-dedicated flash units, especially
studio strobes, have sync voltage in excess of 50 to 60 volts DC.
This voltage level is excessive for almost every currently made
camera and lens.
Some flashes
may even generate voltage in excess of 200 volts. For example,
some Vivitar 283 's flashes generate 280 volts DC which can
quickly damage your camera's sync contacts.


How to test the trigger sync voltage of your flash
How to test the trigger sync
voltage of your flash
It's easy to test any electronic flash for trigger circuit voltage
level using a standard voltmeter. Digital voltmeters are
relatively inexpensive and easy to find at stores like Radio
Shack. The plus (+) lead is attached to the positive contact in
the PC sync cord, while the minus (-) lead is attached to the
ground contact of the PC contact on the sync cord. With hot shoe
flash units, the plus lead should be placed on the + contact in
the middle of the hot shoe , while the minus lead should be
grounded on the hot shoe's ground terminal, usually located on the
side above the lock nut. Usually the voltmeter or multimeter has
several different settings for DC voltage depending on the range
you're trying to measure. With an unknown strobe, it's best to
start in the high range just in case.

usefull info.

Beware of Killer
Strobes
Did you know that some Vivitar 283 and Vivitar 285 's have
voltages of 300 Volts and above !
