Efficiency measurement
Table 1
Vac the full load efficiency is 93.3 % and at 115 Vac it is 90.8 %. Average efficiency
measured at 25 %, 50 %, 75 %, and 100 % of nominal load is higher than 90 %.
The average efficiency has been calculated according to ENERGY STAR
Results are summarized in the following figures.
