Encyclopedia
The Sunpak auto zoom 600 is a thyristor
-based flash
.
It has a flash head capable on being adjusted between 0 and 90 degrees with stops at 0, 60 and 90 degrees.
The flash distance can be adjusted for 35, 50, and 135 mm lenses (with respect to 35 mm film
).
Thyristor
A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased .Some sources define silicon controlled rectifiers and...
