Product Description

Most power supplies operate using DC voltages.  

DC Motor EMI Filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents.  

This allows for the device to work correctly by diverting unnecessary noise.

This series carries CE and UL approvals and offers a current range from 1 to 300A with nominal voltage up to 1000 Vdc.

Introduction of DC Motor Line Noise EMI Filter:

Rated current: 0.5~300A

Working voltage: 0~250VDC

Various terminals: wire, solder lug, stud

Custom specific versions on request

Typical Applications of DC Motor Line Noise EMI Filter:

Suitable for switch power supply, SPC exchange and other DC electric device

Features and Benefits of DC Motor Line Noise EMI Filter:

• General purpose DC filters with good attenuation performance at frequency range 150KHz~30MHz.
• Compact structure, high performance-cost ratio, easy to install, safe and reliable. 
• FT110D and FT111D series are one-stage common mode filters with almost the same filtering effect, only slight difference according to different current. 
• High voltage versions above 250VDC are also available upon request.

Technical Data of DC Motor Line Noise EMI Filter:

1. Storage of DC Motor Line Noise EMI Filter:  

The DC EMI 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 DC Motor Line Noise EMI Filter:  

• DC 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 DC EMI 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.
