DEFINITIONS
VOLTAGE REGULATION –
The A.C. line voltage is a number indicating the nominal
electrical potential that has been adopted by a region for powering electrical
equipment of all kinds. In the United States and Canada it is 120 volts; in Japan, 100
volts; and in many other countries 220 to 240 volts. The actual voltage can fall below or
rise above this nominal level due to brownouts, power cutbacks, use of substandard
wiring, and other causes. These deviations can cause poor performance or
malfunction. A regulator is a device which, through use of a transformer, corrects the
voltage deviation by stepping it up or down so that it is as close as possible to the
nominal level.
SPIKE –
A pulse of energy on the power line. Spikes can have voltages as high as 6000 volts.
Though they are usually of very short duration, the energy they contain can be
considerable, enough to damage sensitive solid-state components in audio and
computer equipment. Spikes can also foul switch contacts and degrade wiring
insulation. They are an unavoidable component of electric power. They are caused
unpredictably by electric motors switching on or off (on the premises or outside), utility
company maintenance operations, lightning strikes, and other factors. Spikes (also
called surges or transients) are absorbed by special components in the AR3600I to
provide safe voltage levels to protect your equipment.
RFI / EMI INTERFERENCE –
Noise from RFI (Radio Frequency Interference) or EMI
(Electro Magnetic Interference) involves lower voltages and less energy than is found
in spikes, but it is continuous rather than transient in nature. It is not likely to cause
damage, but it can certainly be annoying, producing static in audio circuits, “snow” on
video screens, or garbled data in computers. Noise can be introduced into AC lines by
nearby radio transmitters, certain kinds of lighting, electric motors, and others.
Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be
effectively reduced through use of low-pass filtering.
