Introduction

The UltraMOV® Metal Oxide Varistor series is designed for applications requiring high peak surge current ratings and high energy absorption capability. These devices are primarily intended for AC line voltage applications such as surge protective devices, uninterruptible power supplies, AC power strips, AC energy meters, or other products requiring suppression of high transient surge current voltages arising from lightning strikes, inductive load switching, or capacitor bank switching. The series is available in 7 mm, 10 mm, 14 mm, and 20 mm radial lead package sizes with multiple lead configurations. These varistors feature an approved epoxy encapsulation, rated for ambient temperatures up to 85°C with no derating required. The series uses laser marking and is available in bulk or tape-and-reel packaging.

Features

• Lead-free, halogen-free, and RoHS compliant
• High peak surge current rating up to 10kA (single 8×20μs pulse, 20mm type)
• Standard operating voltage range compatible with common AC line voltages (130 VAC to 625 VAC)
• High-temperature operation capability with operating temperature range up to 125°C (phenolic coating option)
• 10mm, 14mm, and 20mm devices UL recognized and TUV certified with 800V isolation voltage rating

Applications

• Surge protection device
• Uninterruptible power supply
• AC power outlet
• AC power meter
