Power Losses
Figure 2-16 shows the power loss for the MICROMASTER 420 Inverters. The
graphs can be used to read either the loss at full load of a particular variant or to
read the part load loss. For example, the full load loss of a 0.55 kW 400 V inverter
is 52 W; the loss from a 2.2 kW 230 V unit at 50% load is approximately 82 W.
