480 V para modelos 380...480 V para altitude até 2000 m. Para altitude maior a redução da
tensão será de 1,1 % para cada 100 m acima de 2000 m - altitude máxima: 4000 m.
Voltage tolerance: -15 % to +10 %.
Frequency: 50/60 Hz (48 Hz to 62 Hz).
Phase imbalance: ≤3 % of the rated phase-to-phase input voltage.
Overvoltage according to Category III (EN 61010/UL 508C).
Transient voltage according to Category III.
Maximum of 60 connections per hour (1 per minute).
Typical efficiency: ≥ 97 %.
Typical input power factor:
- 0.94 for three-phase power supply models in the rated conditions.
- 0.70 for single-phase power supply models in the rated conditions.
