AC Line/Load Reactors

AC Line/Load Reactors
Three Phase Reactors, Harmonic Compensated and IGBT Compatible. Increase Drive System Reliability. Filter Power Line Disturbances. Reduce Harmonics, Surge Currents & dV/dT. Extend Transistor Life. Reduce Motor Noise, Temperature and Voltage Doubling Effects. Improve True Power Factor. Absorb Power Line Spikes. Choose your Impedance Value: 3% to absorb power line spikes, motor current surges and prevent nuisance tripping; 5% to reduce harmonic distortion, surge currents and extend motor life.


DC Link Chokes
1000 Volts DC, Filters 300/360 Hz., Ripple Current. Add in series with the Internal DC Bus to Reduce AC Input Line Harmonics. Absorb Voltage/Current Spikes. Reduce AC Ripple on DC Bus. Solve nuisance Overvoltage Tripping.


Matrix Harmonic Filters
Solve the problems of Harmonic Distortion on virtually any kind of Six Pulse Rectifier. Use with Adjustable Speed Motor Drives, Uninterruptible Power Supplies (UPS), Welders, Battery Chargers, Servo Drives.

Matrix Harmonic Filter

RFI/EMI Filters
Single & Three Phase, 50/60 Hz., Ratings up to 600 Volts. Type "RF" Filters can prevent Drives & Inverters from interfering with other sensitive electronic loads by reducing both common mode and differential mode noise emissions.

RFI/EMI Filters

Motor Protection Filters
Designed to protect AC Motors from the destructive effects of long cable runs between an Inverter & Motor.
