Table 4.3 Mains Supply 3x380–480 V AC - Normal Duty
1)
1) Heavy duty=150–160% current during 60 s, Normal duty=110% current during 60 s.
2) The typical power loss is at nominal load conditions and expected to be within
±
15% (tolerence relates to variety in voltage and
cable conditions).
Values are based on a typical motor efficiency (IE2/IE3 border line). Motors with lower efficiency add to the power loss in the frequency
converter and motors with high efficiency reduce power loss.
Applies for dimensioning of frequency converter cooling. If the switching frequency is higher than the default setting, the power losses
may rise. LCP and typical control card power consumptions are included. Further options and customer load may add up to 30 W to the
losses (though typical only 4 W extra for a fully loaded control card, or field bus, or options for slot B).
For power loss data according to EN 50598-2, refer to www.danfoss.com/vltenergyefficiency.
3) Measured using 5 m screened motor cables at rated load and rated frequency for enclosure sizes J1–J5, and using 33 m screened
motor cables at rated load and rated frequency for enclosure sizes J6 and J7. For energy efficiency class, see the Ambient Conditions
section in chapter 4.2 General Specifications. For part load losses, see www.danfoss.com/vltenergyefficiency.
