Description
The UltraMOV
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 Surge Protective Devices (SPD), 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 have 25mm square forms are produced
in a radial lead package and offered with straight leads.
UltraMOVs are manufactured with recognized epoxy
encapsulation and are rated for ambient temperatures
up to 85°C with no derating. This 25S Series is
LASER-branded and is supplied in bulk packaging.
