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 2 hours.
Turn on the power supply (modeling lamp off) and let it sit idle for 2 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.
