1 UltraMOV 25S Varistor Sris RoHS Dscription Th UltraMOV 25S Varistor Sris is dsignd for applications rquiring high pak surg currnt ratings and high nrgy asorption capaility. UltraMOV varistors ar primarily intndd for us in AC Lin Voltag applications such as Surg Protctiv Dvics (SPD), Unintrruptal Powr Supplis (UPS), AC Powr Taps, AC Powr Mtrs, or othr products that rquir voltag clamping of high transint surg currnts from sourcs such as lightning, inductiv load switching, or capacitor ank switching. Agncy Approvals Agncy Agncy Approval Agncy Fil Numr UL1449 E32116 Ths dvics hav 25mm squar forms ar producd in a radial lad packag and offrd with straight lads. UltraMOV 25S varistors ar manufacturd with rcognizd poxy ncapsulation and ar ratd for amint tmpraturs up to 85 C with no drating. This 25S Sris is LASER-randd and is supplid in ulk packaging IEC , IEC6151-2, IEC (Annx Q) Additional Information Datasht Rsourcs Sampls Faturs Lad fr and RoHS compliant.
