Rotating light 125 V DC supply
Rotating light 125 V DC supply
(OP)
Hi I am looking for a rotating light that can be supplied from a 125 v
DC supply, I can not seem to find one.
In our current installation the following is used
http://www.federalsignal-indust.com/product/371-co...
But these guys don't make 125 v DC anymore,
Any suggestions either I can buy a converter from 125 v dc to 120 V ac ( expecting a suggestion)that could do that conversion, or a replacement that could be powered by 125 v dc.
Thanks in advance.

RE: Rotating light 125 V DC supply
I have also used an IDEC power supply and dropped the 125VDC down to 24VDC, more options available. I use the PS5R series, they have a broad range AC and DC input and have been reliable for me,

If a strobe will do, you can get one that will take 125VDC directly. Here is the first one I found with a brief search-

I do not know how its performance will compare to the 200 watt sealed beam you have been using.

Thanks for your response .
Wayne,
You talked-about performance, I noticed that commander 371L at 120 v ac ,200 w sealed lamp has 36000 candela,
On the other hand xenon strobe kight 97 series from EDWARD SIGNALING has 800000 candela,

Please see under the documentation section, I thin it's candela are higherprobably a serious kick compared to commander lamp, Am I missing anything ?? Which might tell me that lamp was brighter.
RE: Rotating light 125 V DC supply
Also worth mention, LED products have become very popular within the past several years. Sealed beams and strobes are close to obsolete in the emergency vehicle business today, mostly due to the LED's power draw and maintenance advantages. My experience is that most people perceive an LED as overwhelmingly bright compared to strobes or sealed beams.
What exactly is your application?

SF6 leakage , so the horn blows and now beacon is not in picture any more, this xenon strobe will flash.

In case I have to do a layman's comparisons, a commander 371L A3
Rotating beacon can do fine for all these years, this .2 amp running strobe should do just fine.
Is this comparison acceptable ?
RE: Rotating light 125 V DC supply
Ideally you want something which is happy with the supply between about 90V and 160V or so. I actually like catserveng's suggestion - use a wide-range switchmode power supply to derive a stabilised 24V from the station battery and run your beacon from the 24V.
RE: Rotating light 125 V DC supply
It can handle from 72- 125 v DC and can handle extra 10 percent over.
I think this should make the cut ?
