Thermal resistances and losses
Single-phase supply voltage: 100…120 V 50/60 Hz
Single-phase supply voltage: 200…240 V 50/60 Hz
Three-phase supply voltage: 200…240 V 50/60 Hz
(1)See definition on page 15. The table takes into account a 10% margin.
(2) K/W: kelvin per watt
(3)Concentrated heatsource
(4)These losses take into account the derating used for switching frequency.
