Inverter Series Reactors


Product Introduction

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

Features and Benefits

Working Conditions:

-- Ambient temperature: -10℃~+45℃ no decreasing of the rated value, highest temp. +55℃;

if above 45℃, the rated current decreases 2% with the temperature increases 1℃.

-- Working place not higher than 2000 meters above the sea level.

-- Operation temperature: -25℃~+45℃, relative humidity ≤90%.

-- No harmful gas, no flammable or explosive articles.

-- With good ventilation, if installed in cabinet, please add ventilating equipment.

Product Standard:

-- IEC289: 1987 Reactor

-- GB10229-88 Reactor( eqvl EC289:1987)

-- JB9644-1999: Reactor for Semiconductor Electric Drive


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 ten times of the rated value of iinverter) .

Reminding and Warning:

Please read carefully all the safety warnings and instructions before installing reactors and putting them into use:

■ Study thoroughly the product instructions to have a full understanding of its performance, structure, dimensions, weight, installation method, etc.

■ Check carefully the part number and manufacturer of reactors before installation to see if they comply with the design drawings, installation is forbidden if there is any difference. Also it is crucial to check the working voltage and withstand voltage of reactors.

■ If there is no holes on the mounting bracket, punch holes first according to the installation dimensions; otherwise you can install directly. Tighten the screws to the ultmost. Reactors should be mounted steady and stable with inclination no more than 5°, and they must be earth connected after installation. 

■ Reactors shouldn’t be hanged, but fixed horizontally on a racket. Please take the electrical safety distance between the copper bar, winding of reactor and the chassis into consideration to make sure the installations are compliance with the related safety standards and beneficial for heat dissipation.

■ Connect reactors strictly according to the design drawings to avoid wrong wiring:

For low current versions with wire beezer terminals, normally the black wire is input and the white is output( reactors are equipped with black/white silica gel tubing sleeve). For copper bars, the upper is input and the bottom is output, and the faying surface should be well contacted. Screws to fix the wire must be tightened, and make sure the copper bars are not squeezed nor dragged for large current versions after installation.

■ For reactors without warning signs( Reactors supplied by FILTEMC have yellow high temperature warning label and electric shock warning label), please add the cautionary labels after installation to prevent accidents.
