( ) HOW TO SELECT A VARISTOR(ONLY REFERENCE) A: a V=a v/b c V v (, 14 ) b 0.8 c 0.9 A:Varistor voltage Varistor should be more than the operating voltage in over protective circuit,the formula is shown as the following. V =a v/b c V a-power ripple coefficient usually v-dc (significant value only AC power) b-tolerance usually take 0.8 c-ageing coefficient usually take 0.9 B: % B:Withstanding surge current In general, withstanding surge current is max, Pulse current value which determined by test conditions such as wave- shape,amplitude and intermal time, when the amplitude decrease to % of the initial, it should be increased to 2 times of the initial in order to keep the life longer, the surge current which is sbsorbed by the varistor should be less than max. withstanding surge current C:Warnings 1)It is recommended that the circuit voltage which is applied on a steady basis to be used at 80% or less of the max operating voltage. Exceeding the specification will cause deterioration, short-circuits and etc. 2 Select proper products according to the surge energy and the number of the impressions if the varistors are used to absorb the surge for an inductive loading. 3)Give consideration on the layout of the ambient parts not to be fixed close to combustible materials and to take measures on the circuits (fuses or thermo fuses) in case of varistors' short-circuit due to an excessive surge over the rating. 198
