EC635 - Designing with thermally protected TMOV Varistors in TVSS Applications
NOTES Designing with thermally protected TMOV Varistors in TVSS Applications Introduction Metal Oxide Varistors (MOVs) are commonly used to suppress transients in many applications such as: Transient Voltage Surge Suppressors (TVSS), Uninterruptible Power Supplies (UPS), AC Power Taps, AC Power Meters or other products.
Lightning, inductive load switching, or capacitor bank switching, are often the sources of these over-voltage transients.
Under normal operating conditions, the AC line voltage a
