UltraMOV™ Series Ratings & Specifications
Power Dissipation Ratings
Should transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
need to be derated at high temperatures as shown in
above. Because varistors can only dissipate a relatively
small amount of average power they are, therefore,
not suitable for repetitive applications that involve
substantial amounts of average power dissipation.
