Review on Altronix Proprietary Power Supply AL175ULB by Daniel Beaver

The contractor wanted several thousand dollars for a new door entry system. I checked myself with millivolts and found that the current is coming out of the transformers but not going to the timer or controller. Order that specific part, replace it, and the boom timer will light up and be ready to program. Download the manual program from the Altronix website. After programming, the system works like new.
