SJB920 Inverter Input Filter Harmonic Interference

Product Introduction

(Terminal block wiring method is available for this series of products)

Rated current - optional up to 1600A

Bolt or terminal block connection options available (copper busbar connection for currents above 300A)

The SJB920 series is a standard product suitable for most frequency converters

Can be custom-made according to specific interference requirements at customer sites

Features and Advantages

-- The SJB920 series is specifically designed based on the frequency domain characteristics of interference generated by the input of frequency converters during operation, affecting the power grid and other digital devices

-- Utilizes a three-stage filtering design, with special magnetic materials ensuring high impedance characteristics across a broad frequency range

-- Effectively ensures the normal operation of electronic equipment around frequency conversion devices, addressing the drawbacks of interference from frequency converters

-- For specific customer groups, choosing terminal block products ensures reliability under special conditions

-- For currents above 300A, copper busbar connection is used, aligning with design standards for convenient customer connection

-- Optional high operating voltage products including 660VAC/690VAC/1140VAC and above

Application Areas

Widely applicable to frequency converters, servo motors, variable frequency power supplies, and other industrial electronic devices operating on frequency conversion principles
