Series A Sine Wave Filter New MTE Series A sine-wave filters provide a sine-wave output voltage when driven from PWM inverters with switching frequencies from 2 kHz to 8 kHz. For drive applications, these filters eliminate the problem of motor insulation failures and reduce electromagnetic interfer-ence by eliminating the high dV/dT associated with inverter output waveforms. For alternative energy applications, such as wind driven generators, where an inverter is used to return power to the utility distribution system through a step-up transformer, these filters meet the requirements of IEEE-519 and permit the use of standard transformers. Harmonic voltage distortion feeding a trans-former at full load and at 60 Hz is 5% maxi- mum. Harmonic voltage distortion feeding a motor at full load and at 60 Hz is 5% typical. The Sine wave filter is available in 200Ֆ230 380-480, 550-600 VAC and for motors from 1.5 to 700 Hp Panel-mount or NEMA 1, 2 and 3R enclosures are available. Typical applications include submersible pumps, low voltage drives feeding medium voltage motors, HVAC equipment, wind turbines and applications where the distance between the motor and the inverter is up to 15,000 feet. The Sine Wave filter has a continuous current rating of 100% RMS and intermittent current of 150% for 1 minute. Sine Wave Filters help eliminate the high dV/dT associated with inverter output waveforms in applications where the distance between the mo-tor and the inverter is up to 15,000 feet.

Add MTE DC Link Chokes in series With the internal DC bus to: Reduce AC input line harmonics Help meet IEEE-519 limits Absorb voltage/current spikes Reduce AC ripple on DC bus Reduce dv/dt and di/dt rates > DCLINKCHOKES Solve nuisance over-voltage tripping Reduce DC Bus transient over-voltage When added between the input rectifier and bus capacitor the link choke will im-prove the DC bus waveform and the AC input waveform. In this location the DC reactor will reduce the amount of AC rip-ple on the DC bus, reduce the AC input line harmonics and offer protection against nuisance tripping due to...

Installation of surge protection modules issimple > the green wire is connected to your systemground terminal. The other wires connect to each ofyour three phase conductors. can befactory installed and wired onto a Three PhaseReactor. In this installation the reactor and surge protection module work together for maximum atten- uation of spikes. The reactor helps to extend the module life by attenuating the most severe parts of the spike.
