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.
