Will a magnetic transformer work with my Unison Foundry Phase Adaptive Dimmer?


When installing a magnetic transformer to a phase adaptive dimmer, there may be symptoms if the loads not turning on, shimmering, or popping off and back on. This applies to all Echo distributed, ERP, and Foundry Phase Adaptive Dimmer products. 

Description/Explanation of Issue

A Magnetic transformer that is under-loaded may not respond in a desired manner.  


  1. Get as close to max load as you can on the transformer. Ex: If you have a 75w transformer, use as close to 75w on the load side as you can. 
  2. Replace with an Electronic transformer.
