[RE-wrenches] Flourescent lamps

[Exeltech]

Mac,

Check the power factor on one complete lamp assembly.  If you can't test it for yourself, either have someone do it for you .. or contact the lamp manufacturer and get the actual specifications.  Some of the new electronic ballasts present a leading power factor, which if sufficiently capacitive (leading PF) .. can cause instabilities in the output voltage control loop of some inverters.  (The "why" is very technical.)

Next, contact Magnum and talk with  one of their exceedingly knowledgeable engineers.  Tell the engineer the real and the reactive aspects of the **entire** load, and ask if this will pose a problem in that particular model inverter.

Hello wrenches,
 
Has anyone used a Magnum PAE 4448 with T8 bulbs.  I am putting together a quote that has a significant flourecent lighting load.  I haven't heard that this is an issue but I thought I'd check the list.

Thanks in advance
