Technical data

Power and current:

Nom. input current of the converter InIN :effective input current of the converter ( depends from cos Φ of a motor and other)
Nom. output current of the converter:nominal and maximum permanent output current of the converter
Motor power: recommended maximum power of a motor connectable to converter's output (holds for 4 - pole motors)

InQ - nominal output current of the converter for variable load
InL - nominal output current of the converter for constant load
InL60- maximal output current of the converter that is equalled 1,5 x InL for the duration of 60 s each 10 min (this relates only to constant load)
InL2 - maximal output current of the converter that is equalled 2 x InL for the duration of 2 each 15 s (this relates only to constant load)

The type of the converter M ~ variable load M ~ constant load
Motor output rating Pnom [kW] Nominal output current of the converter InQ [A] Motor output rating Pnom [kW] Nominal output current of the converter Inl Maximal output current of the converter InL60 [A] Maximal output current of the converter InL2[A]
