Wanted LED Flasher controler

[jdh]

I am looking for a positive switching, 12 volt LED flasher that is capable of handling 20 amps. Must have the option to steady burn.

Thanks

Admin, I incorrectly listed this in the vintage section as well. Please remove as I did not intend to list this as vintage.

Wow, 20 amps for an LED flasher? That would be something like 20-30 LED lightheads. I think you might be overestimating.

If you really need that much, you're probably going to have to run relays off the outputs of a standard flasher.

The Whelen PFLASH manual indicates it is to be fused at 30 amps when flashing two dual Pioneers. It appears to be a four-channel flasher with four outputs for +12v DC and four outputs for ground. There is one input listed for flashing and one input listed for steady burn.

Yes. I have a bar that has 16 led heads. They each draw an amp. That is 16 amps. If I get something that supports 20 amps, then I have plenty of head room for inrush current.

Thanks I will investigate that flasher

Might be worth picking up a liberty IO board or similar for the application.

Whelen SLFlash May also b an option.

Whelen ULF44, with four channels x 5A each.

You're probably right! I thought I remembered that the ULF44 could handle 20A total.

Before I posted I checked the ULF44 installation guide. What's curious is that it calls for a 10A fuse.

The current Whelen flasher catalog lists the ULF44 at 240W (20A @ 12V) total power output.

"Theoretically" it would never flash both channels at the same time so it could get away with a 10 amp fuse..

He said a must was steady burn so you'd still need 20a...
