Application Note

How to select SAS Zinc Oxide Varistor:

1.To identify the source of surge, measure the surge current and Transient energy from circuit.

2. Check The Clamping Voltage of Varistor > Real clamping voltage from circuit.

3.Checking the ZOV Varistor Withstanding Surge Current and cycle time is sufficient for protection. Select the max. allowable Voltage of Varistor by power input.
