Cost Effectiveness of Using Buck-Boost Transformers
... $600 cost savings using a 750 VA buck-boost transformer over a 7,500 VA distribution transformer. Some larger tanning beds require 3 phase power, so using two transformers in the same example above will save the customer approximately $1200.00 and a lot of floor space. Multiply this by the number of ...
