ROV metal oxide varistors help protect power systems from damage caused by transient overvoltage faults such as lightning, power contact, and power induction. Suitable for a broad range of applications, ROV devices help protect sensitive electronic equipment from potential power surge damage by clamping high- energy, short-duration impulses. The ROV’s high current handling and energy absorption capability, fast response and low cost make it suitable for overvoltage protection in telecom, datacom and security systems, surge strips, power supplies, control board transformers and electric motors. ROVs(metal oxide varistor) can also be used to help protect electrical equipment from damage caused by large voltage or power transients on the AC Mains inputs. In a coordinated circuit protection scheme the ROV can be paired with a PolySwitch overcurrent protection device to help improve equipment reliability and fulfill IEC-61000 test requirements.
