THE CONFIGURATION BEHIND THESE RATINGS

Minimum tested model: 56S(c1)(d1)A(f)(g)(h)(i)(j)

The catalog model is 56S(c1)(d1)J(f)(g)(h)(i)(j); the source identifies 56S(c1)(d1)A(f)(g)(h)(i)(j) as its minimum tested model. The output ratings and load-specific efficiency values below belong to that tested configuration.
