i3 ™ Three-Stage Circuit Topology — Power Protection for the Real World
iPOWER's i3 ™ (instantaneous, impenetrable, and virtually indestructible) circuit topology represents
a breakthrough in power protection technology. A three-stage design comprised of Gas Tubes, Metal
Oxide Varistors (MOV's) and a proprietary Low-Impedance In-Line Filter, the i3
™ circuitry delivers
instantaneous protection.
Most MOV-based surge protection devices use a circuit topology that is sacrificial in nature. Like an
air bag in an automobile, they are designed to “blow up,” sacrificing their internal circuitry in order
to protect the connected equipment during a severe surge event. Sooner or later they fail in the line
of duty leaving connected equipment unprotected. As a radical departure from this philosophy, all
Niles iPOWER
™ products with i3 ™ protection technology are non-sacrificial in nature. This unique
design enables iPOWER ™ to protect your equipment time and time again.
While UL’s ® most rigorous standard for voltage let through is 330 volts, Niles iPOWER ™ products
with i3 ™ protection technology have a consistent clamping level of less than 300V. In addition, all
iPOWER ™ products clamp at a mere 40V over peak standard line voltage (ANSI/IEEE C62.45
6000V 100 kHz Ring Wave Test), adding a level of protection rarely found in the industry.
iQ ™ Optimal Q Noise Filtration
All of the Power — None of the Noise. Computers, household appliances, and RF broadcasts can
introduce "noise" onto the AC power line, obscuring audio detail and video resolution. By their very
nature, conventional AC power line noise filtration circuits limit electrical current flow, stealing the
“punch” from high-current power amplifiers. The Niles iPOWER iQ
™ optimal Q impulse noise fil-
tration circuitry simultaneously achieves both noise reduction and the proper power line loading
necessary for dynamic performance. Through careful research and with the deployment of
advanced electrical components, a sophisticated
design that varies the Q of the circuit topology was
created. With this design, iPOWER
™ products achieve
an outstanding 50dB of common mode rejection and
60dB of differential mode rejection—without current
choking. iPOWER
™ delivers both the performance
and the power.
iQ ™ reduces up to 99.9% (60dB) of AC power line noise.
