You might want to consult your Whelen manual regarding using this
power pack for 3 or 4 strobe heads. What is your power supply model?
Most Whelen and Nova power supplies only supply rated power to HALF
the number of heads. Most units only supply half power when using
more than half the maximum number of strobe heads. My Nova 904 can
run up to 6 heads. However, this means that each capacitor must power
2 heads rather than 1. This cuts the charging time (and therefore the
power output) for each head, in half.
This could become an issue when your DAR makes his/her inspection.

Hello
Redoing my lower dash panel.

1 I have a Whalen strobe powerpack that can handle either 1,2,3
or 4 strobes. It is 14v 7a unit . I have 2 wingtip , 1 tail and 1
red strobe/ beacon.

My question is if I could use a [ 2-10 ?] switch to control this
strobe power unit and have the red beacon turn on the middle switch
position and then add the other 3 strobes at the top switch position?
If that would not do it is there some other arrangment to do it?

2 I have the B + C instrament lighting dimmer setup .
I have Inst. lights, couple of post lights Radio lights ,Lower
dash panel lights , and 2 over the shoulder lights. I have a cabin
ovhd light as well.

I am using Fiber light units on most instraments and on the lower
dash. The lower dash units are a long fiber optic strip that has
lettering on them to label the lower dash panel items.

How should I handle this whole setup?
I only have one dimmer pot .
Do I need some type of rotary switch?
Regular switches or wire the ovhd to a seperate switch? ? wire
them all together?

Any ideas would be helfull

thanks l

Ok My power supply is Whelen A413a 7 amps Can use either 1,2,3,4 lights
are 25 +25 joules or 12 joules or 25 +12 any combination depending if
alternate or simultaneous. Any thoughts on the wiring? Or the dimmer
stuff? I would like to start wiring my panel but am waiting on these 2
issues. Thanks

Nelson,
Did you get an installation manual with this power supply? I ask,
because the A413A is an obsolete model. It has been superceded by the
model HDACF. See

http://www.whelen.com/aviation/catalog/Power%20Supply%20Replacement.pdf

Whelen's installation manual can be found here

http://www.whelen.com/aviation/Avserman.pdf

This unit will not meet the current light requirements, as even in
alternating mode, it only supplies 25 joules. Current requirement is
for approximately 40 joules. Most newer Whelen or Nova units produce
42 joules of light energy.
Running 3 or more strobe heads simultaneously will reduce the output
to only 12.5 joules.
Can you email me an electronic copy of your manual, if you have one?
