AL1200 AL1500 AL82 Ameritron UNSS-AL12-PR HV contactor + soft step start bundle — photo 1

Description

The UNSS-AL12 step start uses a 120Vac trigger. This makes it compatible with the AL82, 1200, and 1500 amplifiers. I am the original designer of the AL12 series of amplifiers. This is my newer design of the AL12 step start with a heavier HV power relay system included.
