MFC “P” Filter Kit – Sine Wave Filter Kit with PQconnect
The MFC Filter Kit is a harmonic filter component package designed and developed by TCI to allow
qualified customers to build sine wave filters to for the output of VFDs. The filter components are
designed to filter out PWM switching ripple when applied correctly and following the schematic
connections used by TCI. The MFC Filter Kit is available for 480 Volt and 600 Volt systems. When
properly designed, assembled, and installed, the completed product is intended to be suitable for use
with 3-phase PWM AC VFDs.
The MFC “P” Filter Kit component package consists of the following components:
•
A KTRMG or KLRUL series filter reactor.
o
The 480 V/900 HP and larger units include two reactors that need to be wired in
parallel.
•
High-endurance, PWM ripple current rated capacitors.
o
Bleeder resistors to ensure safe capacitor discharge on filter shutdown, located on
capacitors.
•
Capacitor mounting brackets
o
Capacitor mounting brackets are provided on kits rated 50 Amps and higher.
o
Kits below 50 Amps are not provided with capacitor brackets because these units
utilize single phase capacitors that do not have mounting brackets available for them.
These small size single phase capacitors are typically mounted vertically due to the
small size and reduced use of panel space.
•
PQconnect connectivity option
o
Modbus RTU over RS485 communications, preventative maintenance detection such
as peak overvoltage or high frequency output
•
Note: There are no damping resistors included, these kits are most suitable for VFD
applications with low load and VFD dynamics
