Powering up Whelen Edge


Registered Member
I’m looking into getting a Whelen Edge. What power sources do you guys use?
I bought an Astron RS50a off eBay to power up some sirens. Any idea if this power supply is good for light bars?

50 amps should be OK. But it depends on the edge, and what options it has. So a 4 strobe, 4 flasher bar would draw ~ 20 amps to be safe. The more strobes/halogens obviously more amp draw.

I calculated, one time, a 4 outlet power supply would draw 10 amps there about.
