Technical Data:

1. Varistors Voltage:

The voltage between two terminals with the specified measuring current 1mA DC applied is called V1mA,The measurement shall be made as fast as possible to avoid heat affection.

2.Maximum Continuous AC or DC Voltage:

Maximum Continuous AC Voltage 0.62multility varistor voltage.

3. Leakage Current:

The current passing through the varistors at the maximum continuous DC voltage.

4.Clamping Voltage:

The peak voltage at class current (Standard surge currentwaveform is 8/20μS). The class current is a peak value of current which is1/10 of the maximum peak current for 100 impulses at per minute for 8/20μS.

5.Energy: The maximum energy within the varistors voltage change of ±10% when one impulse of 2ms or 10/1000μS is applied.

For the 2mS waveform:J=2*Ip* Vc*10-3 For the 10/1000μS waveform:

J=1391*Ip* Vc*10-6 Where J -- Energy absorbed in joules.

Ip -- Maximum let-through current in amps.Vc-- Measured clamping voltage in volts.
