Comment:
MICROMASTER Vector and MIDIMASTER Vector are designed for use worldwide and therefore for wide line supply voltage ranges (1/3-ph. 208 - 240
V AC ±10%; 3-ph. 380 - 500 V AC ±10%; 3-ph. 525 - 575V AC ±15%)
For the voltage data, it should be noted that:
-
the operating range of the drive inverter lies between the two specified voltage values - e.g. 208 - 240V,
-
the ±10% does not represent an operating range but only the range which is provided to absorb brief voltage fluctuations.
