Product Description:
The 26.Z1.F04-1010 sine wave EMC filter is produced by KEB for the Z1 Sine Wave EMC Filters series. Positioned at the output of a variable-frequency drive, it reshapes the inverter’s switching waveform into a smooth sine wave so that three-phase machines receive cleaner voltage, less shaft-voltage stress, and lower electromagnetic emissions during continuous plant operation. The filter accepts balanced three-phase power and connects to the bus through copper bars that add 8.2 kg of conductive mass, helping to limit increases in impedance as the temperature rises.
An inductive core of 0.05 mH provides the primary reactance that absorbs high-frequency components created by a drive operating at a switching rate of 2 kHz. The winding supports a continuous thermal load of 250 A, while its dielectric spacing supports a nominal line voltage of 400 VAC. Under full current, the magnetic circuit dissipates approximately 380 W, so enclosure airflow or heat sinking must remove this loss to maintain the coil temperature within acceptable limits. The unit measures 352 mm in width, 270 mm in depth, and 145 mm in height, allowing direct mounting in many standard control cabinets without exceeding common rail spacing.
The insulation system withstands surge events up to 550 V, providing a margin above the nominal voltage for regenerative overshoot or fluctuations in the power supply. Input and output terminals accommodate conductors up to 120 mm², which are secured with lugs on M10 studs to provide low-resistance connections at the rated current. The total assembled mass is 29.8 kg, so the cabinet panel and mounting hardware must provide adequate structural support. This mass also adds mechanical damping that can help control vibration when the filter is installed in mobile equipment. The enclosure must provide sufficient clearance around the terminals for conductor routing and around the filter body for effective heat removal.
