Line Reactors

The addition of a KDR Line Reactor will limit the inrush current to the rectifier, rounding the waveform, reducing the peak currents and lowering the harmonic current distortion.

The addition of a KDR unit to the output of a drive will dampen overshoot peak voltage, reduce motor heating and audible noise, helping to extend the life of the motor.

The addition of a KLR line reactor will limit the magnitude of inrush current, preventing trips and component failures.

Sine Wave Filters

The MotorGuard filter converts the PWM wave form to a near sinusoidal wave form, allowing sensitive applications to take advantage of the efficiencies and savings that PWM output power supplies and drives offer.

The MotorShield filter eliminates harmful dV/dt to result in a sinewave output.

dV/dt Filter

Greatly reduces motor failures on VFD applications by limiting the magnitude of voltage spikes to levels below 1000 Volts and slowing down the rate of change of PWM switching by a factor of three or more.

Power Factor Correction

The PF Guard Capacitor Bank will reduce the demand on your electrical equipment, resulting in improved electrical system capacity and a more effective power supply.

EMI Filter

The KRF filters use a combination of high requency inductors and capacitors to reduce noise in the critical 150kHz to 30MHz frequency range.
