voltage levels
：
220V,400V
。
②
fuse or the Electric leakage chopper
Fuse or leaking current breaker
Please use fuse that conform to the rated voltage
and current level of inverter.
Be used to control the power of inverter, it palys
a role of protecting the inverter. Used to switch run and
stop is forbidden.
③
Magnetic control conductor
Do not use magnetic control conductor for power switch
of the inverter, for which may reduce the inverter life.
④
Input end AC reacter:
It can effectively restrain the harmonics of power supply wire,
or improve the power factor when the imbalance of main power supply
voltage is more than 3%(and the power capacity is larger than 500KVA
at the same time) or when power supply voltage changes dramatically.
⑤
Radio interference filter
Nearby equipment, such as radio receiver, may brings electromagnetic
disturbance noise. The EMC radio interference filter is helpful for reducing
radio noise.
⑥
EMI filter
Reduce the noise conducting by the power supply wire produced by
inverter.
⑦
DC reactor
To inhibit high-order harmonics produced by inverter.
⑧
Braking Resistors and braking Units
Improve braking Torque of inverter, or be used in occasions that ON/OFF
is operated frequently and rotatory inertia is great.
⑨
Output end noise filter
Reduce the noise from output of inverter.
⑩
Input end AC reacter:
Reduce the motor vibration caused by power supply switch waveform.
When wire between inverter and motor is long than 10 meters, which
can also restrain the harmonics.
