Features and Benefits

• Rated current: 6~2000A
• Stud or terminal block optional
• FT330T series are general purpose filters, suitable for most
• inverter brand
• Could be customized according to the real interference
• situation of customer's working field
• FT330T series is designed according to the frequency characteristics of interference generated by inverter
• output when it works towards load.
• Effectively solve the load heating, noise and other abnormal situation in the case of frequency inverters
• connecting with long motor cables, better effect can be achieved if a reactor is applied too.
• Effectively control the common mode interference along the cable to protect load and increase its service life.
• Touch-safe terminal block versions are available to meet the high safety requirement of certain special
• applications.
• Copper bar terminals applied for versions above 250A to keep pace with international standard, easy and
• safe connection.
• 520VAC or 690VAC high voltage versions optional.

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.
