The Norman P808M Power Supply operates with all Series 500 lampheads.
It has four 200 w/s output channels. Each light can be adjusted from 200, 100, 50 w/s or "off" without affecting the other lights.
When using 3 lights, one lamphead can be switched to 400 w/s. When using 2 lights, both lampheads can be switched up to 400 w/s and when using 1 light, the lamphead can be switched to 800 w/s.
The power supply is equipped with an audible alarm which beeps in the event of a lamphead misfire, making it an ideal choice for high volume school photography. The lamphead modeling lamps automatically track the flash outputs, verifying the recycle of the pack.
