Single-phase line chokes, 1RTN type

Single-phase line chokes, 1RTN type

Purpose and design

Single-phase line chokes are used in drive systems powered and regulated by inverters. The line chokes are installed on the inverter supply. The impedance of the choke in combination with the line impedance at the inverter connection point limits the amplitude of the harmonic current drawn from the line. When used in conjunction with a thyristor converter, line chokes limit the propagation of commutation disturbances. The installation of chokes in enclosures with a high degree of protection should be consulted with the manufacturer.

Note:
Upon agreement, we can manufacture a non- standard device with the required technical parameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
