3.4. EFFICIENCY
3.4.1 General
Under the load conditions defined in Table 1 and Table 2. The loading condition for testing
efficiency shown in Table 1 represents a fully loaded system. a ~ 50-60% (typical) loaded
system.and a ~ 20-30% (light) loaded system.
Minimum Efficiency for test purposes are considered to be within ±1.0% of nominal.
