2.4 Load Reactor

(P/N 100610XX)
Load Reactor required on output side of VFD if total
wire length between VFD and vacuum pump is more
than 100' (30 m). Maximum length with load reactor
is 400' (121 m). For best performance, it is recom-
mended to mount load reactor as close to VFD as
possible. Load reactor protects the VFD from short
circuiting. Load reactors maximize pump perfor-
mance by improving voltage and current waveforms
from supply while also eliminating the possibility of
the pump overheating and noise emissions. Reactors
also minimize harmonic current levels within the drive
supply circuit.
Voltage: 460V/3Ø,2HP- 460V/3Ø,3/4 HP-230V/3Ø.
Frequency: 60Hz Fundamental Current Maximum.
