Specific input filters for EP66

Input filters


The input filters Z-EP66-EMV-BG are specially manufactured to be inserted into the interior of the inverter box EP66 series , and that are designed to meet CEM C1 (domestic environment).

There are three models available:

  • Z-EP66-EMV-BGI1 for I1 size drives
    (IIx230Vac ≤2.2kW) / (IIIx230Vac ≤2.2kW) / (IIIx400Vac ≤4kW)
  • Z-EP66-EMV-BGI2 for I2 size drives
    (IIIx400Vac ≥ 5,5kW ≤ 7,5kW)
  • Z-EP66-EMV-BGI3 for I3 size drives
    (IIIx400Vac ≥ 5,5kW ≤ 7,5kW)

Reactances for input and output




They can be used both on the network side and on the motor side. They attenuate micro-cuts and peaks due to the initial connection and switching and reduce the harmonic rate of the mains current. If they are also placed on the motor side, they eliminate harmonic frequencies due to commutation.

Chokes (ferrites) for input and output




Output Chokes can be used in combination with RED filters to reduce electromagnetic disturbance.

They are especially effective when the disturbances radiated by the motor connection conductor cause interference in the control systems, data lines or radio and television receivers located near the installation. Fitting the proper shock on the motor connection cable can solve this type of problem.

Occasionally, electromagnetic compatibility problems can occur in an installation when the components that are part of the same control set affect each other; for example, open control panels can cause interference on the small amplitude signal circuits of the sensors. Usually in these cases the inclusion of a toroidal inductance in the control circuit cables and the sensors solves the problem. Normally, to determine the number and the situation of the additional shocks, it is necessary to perform some tests until the optimal configuration is achieved.

Sine-wave output filters

Output filters


The LC series filters the high frequency carrier of the output voltage of the Variable Speed Drive, above the frequency parameters of the resonance. The output voltage of the filter is essentially sinusoidal with a small harmonic distortion in the ripple of the voltage (5-10%). The emission of noise to the engine is radically reduced and the life of the equipment is increased up to its normal operating levels.

  • Three-phase power 400VAC
  • Large motor cable length possible
  • High lifespan
  • Low noise emissions to the engine
  • Easy installation
