Flash Capacitor
Preventative Maintenance
Proper Care is Essential for Long
Life
One of the most important components of
an electronic flash power supply is the Main Flash Capacitors. By
following the preventative maintenance instructions described
herein longer life will be achieved increasing the flash systems
reliability.
Forming the Main Flash Capacitors
Flash Capacitors must be pampered; this
is accomplished by forming the flash capacitor as much as
possible. Flash power supplies that are not used on a daily
basis, or ones that are stored for long periods of time
definitely need forming.
Constant flashing of your
electronic flash power supply puts a tremendous strain on the
flash capacitor and shortens its life. Forming is just the
opposite, by having a constant calm voltage applied to the flash
capacitor it helps to rejuvenate the chemical properties. This is
very similar to slow charging a car battery to give it an extra
boost.
How and when do you form?
During Use
If your electronic flash is being used
2-3 times (or more) a week make sure that the main power switch
is on during set-up and break down of the set. This will bring a
steady calm voltage to the flash capacitors giving them the
forming time they need. Don't just turn on the model lamp
circuit; make sure that the 100% charge circuit Ready Indicator
Lamp is on.
During Slow Periods
During slow periods or between
assignments it is advisable to form the capacitors at least once
a week for 4-5 hours.
Turn on the power supply and let it sit
idle for 4-5 hours this will give the flash capacitors the
required forming time. It is not necessary nor is it advisable to
flash the unit, just let it sit and absorb this calm voltage.
Note: Never leave the Electronic Flash
Power Supply in the On position if you are leaving the studio.
When leaving turn off the unit and remove the AC plug from the
wall outlet.
Inactive or Stored Units
Electronic Flash Units that are inactive
for months at a time it is advisable to form the capacitors for
6-8 hours each day over a 3 day period prior to using it on an
assignment.
Electronic Flash Units that have
been stored for a year or more, it will be advisable to bring the
unit to an authorizes repair service. The repair service has
special equipment that will bring the Flash Capacitor voltage up
very slowly.
Forming is Important and
can save you money and lost equipment time.
