Name
Descriptions
Cable
Accessory for signal transmission.
Breaker
Device for electric shock prevention and protection
against short-to-ground that may cause current
leakage and fire. Select residual-current circuit
breakers (RCCBs) that are applicable to VFDs and
can restrict high-order harmonics, and of which the
rated sensitive current for one VFD is larger than
30 mA.
Input reactor
Accessories used to improve the current
adjustment coefficient on the input side of the
VFD, and thus restrict high-order harmonic
currents.
Input filter
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.
Braking
resistor
Accessories used to consume the regenerative
energy of the motor to reduce the DEC time.
The VFD models need only to be configured with
braking resistors.
Output filter
Accessory used to restrict interference generated
in the wiring area on the output side of the VFD.
Try to install the output filter near the output
terminal side of the VFD.
Output
reactor
Accessory used to lengthen the valid transmission
distance of the VFD, which effectively restrict the
transient high voltage generated during the
switch-on and switch-off of the IGBT module of the
VFD.
Membrane of
heat releasing
holes at the
side
Accessory
applied
in
severe
environment
scenarios for improving protective effect.
The VFD can be derated by 10% through using the
membrane.
