Device to transfer the electronic signals
Prevent from electric shock and protect the
power supply and the cables system from
overcurrent when short circuits occur.
(Please select the breaker with the function
of reducing high order harmonic and the
rated sensitive current to 1 VFD should be
above 30mA).
This device is used to improve the power
factor of the input side of the VFD and
control the higher harmonic current.
The VFDs of 380V (≥37kW), 500V (≥22kW)
and of 660V have external DC reactors.
Control the electromagnetic interference
generated from the VFD, please install
close to the input terminal side of the VFD.
Accessories
regenerative energy of the motor to reduce
the deceleration time.
VFDs of 380 V (≤30kW), and 500V
(≤18.5kW) need only to be configured with
brake resistors, those of 380V (≥37kW),
500V (≥22kW) and of 660V also need to be
configured with brake units.
Control the interference from the output
side of the VFD and please install close to
the output terminals of the VFD.
Prolong the effective transimiting distance
of the VFD to control the sudden high
voltage when switchiong on/off the inverter
unit of the VFD.
