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 inverter should
be above 30mA).
This devices are used to improve the power
factor of the input side of the inverter and
control the higher harmonic current.
The inverters (≥75kW) have external DC
reactors.
Control the electromagnetic interference
generated from the inverter, please install
close to the input terminal side of the
inverter.
Shorten the DEC time
The inverters (≤55kW) only need braking
resistors while the inverters (≥75kW) need
braking units besides braking resistors.
Control the interference from the output 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
voltage when switching on/off the IGBT of
the inverter.
