PLUGSTRIP AND WALLMOUNT SURGE PROTECTORS
2. Introduction
2.1 General
The Surge Protectors protect your equipment from surges, spikes, and over-
voltages.
2.2 Features
Two general styles of surge protectors are available: the plug-strip models and the
wallmount models.
The plug-strip Surge Protectors come in three different levels of protection:
standard, advanced, and maximum. The standard and advanced models comply
with safety standard UL1449-1997. The maximum models are UL listed to standard
1449, second edition. The plug-strip Surge Protectors also offer the following
features:
• Fax/Modem protection (selected models only)—Some models are available
with built-in telephone line suppression.
• Sine-Wave Tracking—A patented sine-wave tracking technology protects
against surges by providing a tight let-through (clamping) voltage around the
power-line sine wave.
• Low Let-Through Voltage—A lower let-through voltage provides superior
performance and more protection for your connected equipment.
• EMI/RFI Noise Filtration—Electromagnetic Interference (EMI) and Radio
Frequency Interference (RFI) are disruptions on the smooth AC power-line
sine wave. This noise on the power line can be caused by lightning, generators,
radio transmitters, or even household appliances. This noise shows up as
glitches or errors on computer systems or “snow” on a TV. The Surge
Protectors eliminate up to 99.99% of EMI/RFI noise.
• Thermal Fuse—The thermal fuse offers fail-safe shutoff, which safely stops
power in case of a sustained overvoltage or suppressor failure. This prevents
destructive surges from passing through to your connected equipment.
