8 TECHNICAL SPECIFICATIONS
This chapter describes the technical specifications (electrical and
mechanical) of the CFW-11M RB converter series.
8.1 POWER DATA
Power supply:
;
Maximum rated line voltage: 480 V for models 380...480 V, 600 V for
models 500...600 and 690 V for models 660...690 V, for altitude up
to 2000 m. For higher altitudes, the voltage derating will be 1.1 % for each 100 m above 2000 m – maximum
altitude: 4000M.
;
Voltage tolerance: - 15 % to + 10 %.
;
Frequency: 50/60 Hz (48 Hz to 62 Hz).
;
Phase imbalance: ≤ 3 % of the rated phase-phase input voltage.
;
Overvoltage according to Category III (EN 61010/UL 508C).
;
Transient voltages according to Category III.
;
Typical efficiency: ≥ 97 %.
;
Typical input power factor: 0.99 at rated condition.
;
Typical Total Harmonic Distortion of the input current: 4 % at rated condition.
ATTENTION!
When an output inverter is fed by the CFW-11M RB, it is necessary to reduce the rated current of
the output inverter by 5 %.
