Raychem Overvoltage Devices ROV20, ROV20H, ROV20E www.tycopowercomponents.com 20mm Series Metal Oxide Varistors GENERAL DESCRIPTION The ROV20-XXX (Radial-leaded Metal Oxide Varistor) products are 20mm radial leaded varistor devices suitable for protection of overvoltage transients. ROV devices can provide protection for a wide variety of power systems against overvoltage faults such as lightning, power contact and power induction. Suitable for a broad range of applications including, but not limited to security, power supplies, surge strips, etc., the ROV device helps to protect valuable equipment from potential power surge damage by clamping high energy, short duration impulses. The ROV devices have high current handling and energy absorption capability and fast response times to help protect against transient faults. Document: SCD 25484 Status: Released Rev.
