Product Description:
The 15.Z1.C04-1000 is a sine-wave EMC filter manufactured by KEB and assigned to the Z1 Sine Wave EMC Filters series. The unit is installed between a three-phase drive inverter and the motor circuit to smooth the pulse-width-modulated output, cut common-mode noise, and protect motor insulation in industrial automation cells. By presenting a near-sinusoidal voltage to the connected machine, it reduces electromagnetic interference and limits dv/dt stress, making it suitable for conveyor lines, pumps, and fan systems driven by frequency converters.
The filter is designed for a nominal line level of 400 VAC, which aligns with standard low-voltage three-phase distribution systems and matches the dielectric spacing of the winding former. Under that voltage, the device passes a continuous phase current of 25.2 A, which reflects the thermal capacity of its copper conductors and magnetic core. For installations where transient line peaks must be tolerated, the insulation system can withstand up to 440 V AC without partial discharge. Each terminal block accepts cables up to 16 mm², simplifying direct wiring from the supply breaker. When connected to an inverter that delivers 11 kW of motor power, the filter’s impedance matches the carrier frequency so that voltage distortion at the motor terminals remains low.
During continuous operation, the filter dissipates 190 W as heat, a figure used for cabinet ventilation calculations and related to its low differential inductance. The overall enclosure weighs 25.5 kg, and the internal copper mass of 9 kg adds electrical efficiency and thermal inertia. It operates on a network base frequency of 50 Hz in a three-phase topology. Harmonic mitigation keeps the total current distortion to < 8 %, while voltage distortion (PwHD) stays below 15% so downstream equipment receives a clean sinusoidal waveform.
