Revised: 11/12/14 Varistor Products Radial Lead Varistors > UltraMOVTM Series Description 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 85ºC with no derating. This Series is LASER-branded and is supplied in bulk, ammo pack (fan-fold), or tape and reel packaging. Features • Lead–free, Halogen-Free and RoHS compliant. • Highpeaksurge current rating (I TM) up to 10kA, single 8 x 20 pulse, (20mm) • Standardoperating voltage range compatible with common AC line voltages (130 V AC to 625 VAC) • Characterizedfor maximum standby current (Leakage) • Customvoltage types available • Standardleadformand lead space options Agency Approvals Absolute Maximum Ratings •Forratingsofindividualmembersofaseries,seeDeviceRatingsandSpecificationschart Agency Approval Agency File Number UL1449 E320116 CECC 42201-006 IEC 61051-1 IEC 61051-2 IEC 60950-1 (Annex Q) for 14mm and 20mm only 116895 CSA 2221 01 LR91788 CECC 42201-006 IEC 61051-1 IEC 61051-2 IEC 60950-1 (Annex Q) for 14mm and 20mm only E1273/F Continuous UltraMOV™ Series Units Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS) 130 to 625 V Transients: Single-Pulse Peak Current (I TM) 8x20µs Wave (See Figure 2) 1,750 to 10,000 A Single-Pulse Energy Range (W TM) 2ms Square Wave 12.5 to 400 J Operating Ambient Temperature Range (T A) -55 to +85 ºC Storage Temperature Range (T STG) -55 to +125 ºC TemperatureCoefficient(aV) of Clamping Voltage (V C)atSpecifiedTestCurrent <0.01 %/ºC Hi-Pot Encapsulation (COATING Isolation Voltage Capability) 2500 V COATING Insulation Resistance 1000 MΩ CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
