The UltraMOV Metal Oxide Varistor Series is designed for applications requiring high peak surge current ratings and high energy absorption capability. UltraMOV varistors are primarily intended for use in AC Line Voltage applications such as Transient Voltage Surge Suppressors (TVSS), Uninterruptable Power Supplies (UPS), AC Power Taps, AC Power Meters, or other products that require voltage clamping of high transient surge currents from sources such as lightning, inductive load switching, or capacitor bank switching.
- These devices are produced in radial lead package sizes of 7, 10, 14, and 20mm and offered in a variety of lead forms.
- UltraMOVs are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85°C with no derating.
- This Series is LASER-branded and is supplied in bulk, ammo pack (fan-fold), or tape and reel packaging.
- Lead–free, halogen-free, and RoHS compliant
- High peak surgecurrent rating (Itm) up to 10 kA, single 8/20 µs pulse (20 mm)
- Standard operatingvoltage range compatiblewith common ACline voltages (130VAC to 625 VAC)
- Characterized formaximum standbycurrent (Leakage)
- Custom voltagetypes available
- Standard lead form and lead spacing options
