Introduction of DC RFI Filter:

Rated current: 0.5~300A
Working voltage: 0~250VDC
Various terminals: wire, solder lug, stud
Custom specific versions on request

Features and Benefits of DC Line 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.

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

1. Storage of DC Single Phase Power Line Filters: 

•  The DC 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 Filter DC Power:  

• DC RFI Filter 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.
