Name
Cables 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.
Breaker (Please select the breaker with the
function of reducing high order harmonic
and the rated sensitive current to 1 inverter
should be above 30mA).
This device is used to improve the power
Input reactor
factor of the input side of the inverter and
control the higher harmonic current.
The inverters of 380V (≥37kW) and of
DC reactor
660V have external DC reactors.
Control the electromagnetic interference
generated from the inverter, please install
Input filter
close to the input terminal side of the
inverter.
Shorten the DEC time
The inverter of 380V (≤30kW) need
braking resistors and the inverters. The
inverters of 380V (≥37kW) and of 660V
need braking units.
Control the interference from the output
Output filter side of the inverter and please install close
to the output terminals of the inverter.
Prolong the effective transmitting distance
of the inverter to control the sudden high
Output reactor
voltage when switching on/off the IGBT of
the inverter.
