Radial-leaded Metal Oxide Varistor Devices Raychem Circuit Protection's ROV (Radial-leaded Metal Oxide Varistor) devices help to provide protection from overvoltage faults such as lightning, power contact and power induction, for a wide variety of power systems. Suitable for a broad range of applications including, but not limited to, security systems, power supplies, surge strips, motors and telecommunications equipment, the ROV devices help 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. The ROV overvoltage protection devices expand Raychem Circuit Protection's portfolio and can offer the circuit board designer a complete overcurrent/overvoltage solution. For example, pairing an ROV device with Raychem Circuit Protection's PolySwitchTM LVR overcurrent protection devices can help provide a completely resettable circuit protection solution for power supplies, surge strips and control board transformers. In addition, ROV devices can be combined with PolySwitch devices to help provide protection for electric motors, telecom equipment and various other systems.
