Suppresses surges or noise invading from an external source, preventing malfunction from
magnetic contactors, control relays and timers, etc.
Absorbs surges or noise invading from an external source, preventing malfunction of electronic
equipment used in the switchboard.
Arrester
Suppresses induced lightning surges from power source, thus protecting all equipment
connected to the power source.
This is used in cases where a single-phase 115V power supply is used to feed a three-phase
230V inverter. (It can be applied to the inverter of 1HP or less.)
This is a dedicated filter which complies with the European EMC (Emission) Directive.
Used for power factor improvement and power supply coordination. However, it is
recommended that a DC REACTOR with
a higher efficiency and which is more compact and
lightweight be used. Use a DC
REACTOR (DCR) as a countermeasure for harmonics. If it is
necessary to supply a stabilized power supply, such as a DC bus system and running from that
(PN connection operation), please use such a reactor.
Reduces radio frequency noise. If the wiring between motor and inverter is shorter than 66ft (20m),
use the ferrite ring in the power supply side. If longer than 66ft (20m), use it in the output side.
Reduces noise.
For frequencies in the AM radio frequency band of 1MHz or less, a noise reduction effect can be
obtained. Absolutely never connect this device to the inverter’s output side.
[Use the DCR to normalize the power supply in the
following cases.]
1. The power transformer capacity is 500kVA or over and
exceeds the inverter rated capacity by 10 times.
2.
The inverter and a thyristor converter are connected
with the same transformer.
*Check if the thyristor converter uses a
commutation reactor. If not, AC reactor must
be connected to the power supply side.
3.
Overvoltage trip occurs due to open/close of the
phase-advancing capacitor for the power supply lines.
4.
The voltage unbalance exceeds 2%.
Output circuit filter
This filter is connected to the output circuit of inverters, and has the following functions:
1.
Suppressing fluctuation of motor terminal voltage
Protects the motor insulation from being damaged by surge voltage.
2.
Suppressing leakage current from output side wiring
Reduces the leakage current caused when several motors are operated in parallel or
connected with long wiring.
3.
Suppressing radiation noise or inductive noise from output side wiring
Effective noise suppression device for long wiring applications such as plant
* There are two kinds of filters for 460V series. Choose a desired one according to the purpose of use.
