Active Front End (AFE) vacon • 3324-hour support +358 (0)201 212 575 • Email: vacon@vacon.com44.8 Active Front End power ratings4.8.1 Vacon NXA; DC voltage 380–500 VFor dimensions of NXA units, see Table 8 and LCL filters Table 9.NOTE! The rated currents in a given ambient (+40 °C) temperature are achieved only when the switchingfrequency is equal to the factory default.NOTE! The motor output power: P out =P dc x (ηINU x ηMotor).P dc = AFEs DC powerηINU = efficiency of the inverterηMotor = efficiency of the motor4.8.2 Vacon NXA; DC voltage 525–690 VFor dimensions of NXA units, see Table 8 and LCL filters Table 9.NOTE! The rated currents in a given ambient (+40 °C) temperature are achieved only when the switchingfrequency is equal to the factory default.NOTE!
