The V1k dv/dt filter provides motor protection by limiting voltage spikes below 1,000 volts for long lead applications. The KMG eliminates harmful dv/dt to result in a sinewave output.

Voltage Overshoots are harmful to Motors
Voltage wave reflection is a function of the voltage rise time (dv/dt) and the length of the motor cables. As wire length or switching speed increases, the overshoot peak voltage also increases.

Indicators of Harmonic Distortion

• Rapid Breakdown of Motor Insulation
• Bearing Pitting and Fluting
• Damage to Cables
• Motor Heating, Motor Noise, and Motor Vibration
• Instrumentation Noise

Motor Protection Solutions 

KDR
	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. Learn more about the KDR
V1k
	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. Learn more about the V1k
KMG
	The KMG 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. Learn more about the KMG
