Device to transfer the electronic signals
Prevent from electric shock and protect the
power supply and the cables system from
overcurrent when
(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 380 V (≥37 kW) and of 660 V
have external DC reactors.
Control the electromagnetic interference
generated from the VFD, please install close
to the input terminal side of the VFD.
Accessory that restricts the electromagnetic
interference generated by the VFD and
transmitted to the public grid through the
power cable. Try to install the input filter near
the input terminal side of the VFD.
Accessories
regenerative energy of the motor to reduce
the deceleration time.
VFDs of 380 V, 30 kW or lower need only to
be configured with brake resistors, those of
380V, 37 kW or higher and 660 V series 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 transmitting distance of
the VFD to control the sudden high voltage
when switching on/off the IGBT of the VFD.
