Input power supply
transformer
When there is need for matching the system power
supply voltage with rated inverter input voltage, please
provide the input power supply transformer.
When several inverters are used, please provide the
input power supply transformer to reduce the impact of
high-order harmonic on other load devices.
Wiring circuit
breaker
or leakage circuit
breaker
Please connect wiring circuit breaker or leakage circuit
breaker in the overload protection circuit during
protection and wiring of the power supply system.
When using leakage circuit breaker, select a product for
corresponding high-order harmonic.
Electromagnetic
contactor
The coil must be provided with a surge absorber.
Surge absorber
Please install the surge absorber for suppression of surge
generated on opening and closing of electromagnetic
contactors and control relays.
AC reactor
DC reactor
To achieve the following objectives, please install the
reactor
·Improve the inverter’s input power factor
·Reduce the impact on inverter due to unbalance
between phases of power supply voltage
·Prevent tripping of inverter due to action of phase lead
compensation capacitors in the system
·When the capacity of power supply is large (above
500kVA)
Zero-phase reactor
Line noise filter
Reduce the interferences coming into input power
supply system of the inverter and generated by wiring.
It is recommended that elements such as
zero-phase reactor etc. be inserted as close to
inverter as possible.
Radio noise filter
Used to suppress the radio noise radiating to power
supply side of the inverter.
Noise filter
Reduce the interferences coming into input power
supply system of the inverter and generated by wiring.
It
is recommended that noise filter be installed as
close to inverter as possible.
Note 1: For SVC06 series inverter with built-in EMC filter, please place the EMC filter selector switch to ―ON‖.
Note 2: See model selection samples of options of Sanken Inverter for related options.
