ELECTRONICS Metal Oxide Varistors 32D Series Circuit Protection System Specifications are subject to change without notice. Please refer to http://www.ruilon.com for current information. Metal Oxide Varistors - 32D Series Features 1. Wide operating voltage (V1mA) range from 8V to 1800V. 2. Fast responding to transient over-voltage. 3. Large absorbing transient energy capability. 4. Low clamping ratio and no following-on current. General Information The MOV-32DxxxK Series of 32mm radial leaded varistor devices protects against overvoltage transients such as lightning, power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 200 V to 1600 V and Vrms voltages from 130 V to 1000 V. The devices have a high current handling, high energy absorption capability and fast response times to protect against transient faults up to rated limits.

Page:2 Metal Oxide Varistors - 32D Series Current Energy and 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 developed must be within the specifications shown on the Device Ratings and Specifications Table for the specific device. The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation.
