9 Performance Data
All measurements performed at room temperature, 50 Hz input frequency.
9.1 Efficiency
Full power efficiency was measured as a function of line voltage and Figure 6 gives the
resulting profile.
Efficiency as a function of output power was measured at 230V input, each rail load
increased from zero to 100% load simultaneously in 10% load steps. Figure 7 shows the
resulting efficiency profile.
