the goal of enhancing the computing environment, all Zalman
Tech products are noise-free. This product is a noise-free 300(400)W
ATX (version 2.03) / ATX12V power supply supporting Intel Pentium
4 and AMD CPUs. By implementing heat-sensor circuitry that controls
the cooling fan's speed (rpm) in relation to the temperature
within the power supply, emanating noise has been greatly reduced.
- Lightning and Surge Protection - SurgeArrest's
components such as MOVs and Thermal fuse ensure instantaneous
reaction to lightning strikes and wiring faults. If the
surge components are damaged due to power spike or over
voltage, excess power cannot reach your equipment. Unlike
APC's SurgeArrest products, most surge suppressors continue
to let power through even after circuits have been damaged,
leaving your equipment exposed to other damaging surges.
- IEEE let-through rating and UL 1449 compliance
- IEEE tests simulate a surge of 6.000 volts, such as in
a direct lightning hit. Let through rating indicates the
maximum voltage that will reach your equipment when suppressed
by a Surge Protector. . Lower let through rating indicates
better protection. UL's best available rating against devastating
surges and spikes is 330V of let through APC’s Personal
SurgeArrest has 300V let through voltage, thus exceeding
- Data-line Protection Protection - of
DSL, modems, fax and answering machine data lines (T models
only) ensures complete protection of your equipment from
surges. It is very important to protect your equipment from
"back door" surges traveling through data lines,
as they can be as damaging to your equipment as surges traveling
over power lines.
- Noise Filtering - SurgeArrest attenuates
EMI/RFI line noise that can cause data errors and keyboard
lockups, ensuring better performance of protected equipment.
- Catastrophic Event Protection - An MOV
reacts instantaneously to lightning strikes and other spikes.
A thermal fuse shuts down safely if there is a wiring fault.
- Cord Management - To help organize power
- Always on Outlets - 8 outlet models offer
dedicated space to accommodate wide transformer blocks without
covering adjoining outlets and 2 always on outlets. You
can plug 8 power cords including 3 transformers at the same
- Fail Safe Mode - Most other surge suppressors
continue to let power through even after their circuits
have been damaged, leaving your equipment exposed to future
surges. APC's Surge Protectors fail safe, which means that
once the circuit of an APC Surge Protector has been compromised
the unit disconnects equipment from the power supply ensuring
that no damaging surges reach your equipment.
- Protection working indicator - APCs Surge
Protector will warn you if its circuitry has been damaged
by heavy strike or power line surge and it is unable to
provide 100% protection. If still under warranty, APC will
then replace your damaged SurgeArrest free of charge.
- Site wiring fault indicator - In order
to work properly, surge suppressors require a correctly
wired and grounded outlet. APC SurgeArrests identify dangerous
wiring problems and indicate it before you plug in your
equipment. (all except PW5TR)
- Transformer Block Spacing - 8 outlet
models offer dedicated space to accommodate wide transformer
blocks without covering adjoining outlets and 2 always on
outlets. You can plug 8 power cords including 3 transformers
at the same time. In case you have equipment that has to
stay on all the time, such as fax machine, you can plug
it in always on outlets. The equipment will be protected
and will have power supply even when the unit is switched
- Right Angle Plug - Provides real installation
