Raychem Circuit Protection Announces ROV Series of Overvoltage Fault Protection Devices
MENLO PARK, CA- July 1, 2003 - Raychem Circuit Protection, a unit of Tyco Electronics, announces the introduction of its ROV series of Metal Oxide Varistors (MOVs) for overvoltage fault protection on a wide variety of power systems. Suitable for a broad range of applications including security systems, power supplies, and surge strips, the ROV device helps protect valuable equipment from potential power surge damage by clamping high-energy, short-duration impulses.
The introduction of the ROV series expands Raychem Circuit Protection's offering of circuit protection options and can offer the circuit board designer a complete overcurrent/overvoltage solution. The ROV device's high current-handling and energy absorption capability, fast response, and low cost can make it suitable for use in line voltage applications. For example, pairing the device with Raychem Circuit Protection's PolySwitch(TM) LVR overcurrent protection device 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 provide protection for electric motors.
"For many years, circuit designers have relied on PolySwitch devices for overcurrent protection. The addition of the ROV device gives designers the ability to specify a coordinated overcurrent and overvoltage solution from a single vendor," said Kris Beyen, Overvoltage Business Development Manager.
The ROV devices are available in 5 to 20mm diameters, and are rated from 18 to 1800V. The ROV devices are also available in radial-leaded configurations, and can be supplied in tape-and-reel packaging for compatibility with high-volume assembly. Many have UL, CSA and VDE certifications*. For further information or technical assistance, call (800) 227-7040, or visit www.tycopowercomponents.com
*Please consult the Raychem Circuit Protection Databook for details on certifications.
Price Range: $0.03 - 0.30 for 100K/yr based on diameter and voltage
