8 TECHNICAL SPECIFICATIONS
This chapter describes the technical specifications (electric and
mechanical) of frame sizes F, G and H of the CFW-11 inverter line.
8.1 POWER DATA
Power Supply:
Voltage tolerance: -15 % to +10 % of the nominal voltage.
Maximum rated voltage: 480 V for models 380...480 V for altitudes up to 2000 m (6.600 ft). For higher
altitudes, the voltage derating will be 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft) - maximum
altitude: 4000 m (13.200 ft).
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).
Efficiency: according to class IE2 as per EN 50598-2.
Typical input power factor:
- 0.94 for models with three-phase input in the rated condition.
Cos φ (displacement factor): >0.98.
