|PowerGuard Original (PG3701) is
a patent design, Voltage Limiting Device and Surge protector,
and is specifically designed to monitor and limit voltage so
that only voltage within a safe operating window between 190V
AC Low - 265V AC High, flows through to the protected equipment.
The PowerGuard protects by isolating the protected equipment
from potentially damaging power.
The Power Filter range is a combination of a Spike Arrester
and Power “Sifter”. The Power Filter protects
by arresting and diverting potentially damaging high voltage
spikes to earth and cleans (sifts or filters) the AC power
of transient noise by capturing and dissipating the transient
pulses through the filter circuitry to Earth.
