Product Description

An inverter input reactor is specially recommended to be used in the following circumstance:
Several inverters are closed connected in parallel.
There is obvious disturbance(interference, over voltage) from other equipment.
The voltage imbalance between different phases of the power supply is above 1.8% of the rated voltage.
A great number of inverters installed in one circuit.
Decrease the overload of power factor correction capacitor, if there is certain power factor correction device in the cabinet.
Power capacity ≥ 600KVA, and the distance between inverter and the large capacity power supply is within 10m.
The inverter is powered by circuit with extremely low impedance(the transformer capacity is higher than 10times of the rated value of inverter).

Features and Benefits:

  • Provide improved overload protection for power supply
  • Reduce the current harmonic distortion of inverter
  • Increase the power factor of input supply, reduce high order harmonics
  • Restrain the surge to power equipment caused by transformer

Inverter Output Reactor

1. Storage of EMI Filters: 

  •  The DC Power Line Filters mustn't be left out in the heat of the sun or exposed to the rain, it should be stored in warehouse with good ventilation, surrounding temperature between -30℃ and +65℃ , the highest relative air humidity lower than 90%, and no corrosive liquid or gas.

2. Installation of EMI Power Filters:  

  • RFI Noise Filters should be installed at power input, and the line inside the chassis be as short as possible to reduce radiated interference. 
  • Both input and output lines of Inverter filters neither be intersected nor be tied up by string.
  • Make sure the mounting flange fully grounded, and keep the ground cable as short as possible if filters are connected to other equipment. 
  • If the terminal is stud, please use two spanners to fasten the screw nut when connecting to avoid stud rotating and thus causing changes to the internal circuit and consequently leading to filters arcing, short circuit, broken down or the filtering effect worsened. 
  • First use spanner1 to fix the screw nut near the metal case, then use spanner2 to tighten the screw nut in front( shown as Figure1), otherwise the terminals may be damaged. 
  • Apply the same for the connection of other phases.

Requests for samples of any catalog item are available for engineering evaluation Free of Charge.

All EMI Filters are RoHS compliant and approvals held include CE, UL,cUL and TUV.

All quality control procedures are fully documented and available for review. FILTEMC is ISO 9001 compliant.
