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
