The CFR Advantage
ADVANCED POWER PROTECTION TECHNOLOGY
Power protection devices can be judged by the type and quality of power
they provide. Alpha CFR Uninterruptible Power Supplies provide continuous,
conditioned “computer-grade” AC power to electronic equipment such as Computer
Systems, Point of Sale Terminals, Process Controls, Telecommunications, Cable
TV Headend, Broadband LAN, Manufacturing Control Systems, Critical Care and
Hospital Lab Equipment.
SURGE AND SPIKE REJECTION
Alpha's proven design virtually eliminates surges and spikes. The Alpha
CFR UPS provides spike attenuation of 2000 to 1 and meets the requirements of
IEEE 587 / ANSI 62.41.
REGULATION
Unlike many standby power systems, which regulate output voltage
only when operating from their battery backup, the Alpha CFR UPS
constantly mai1% output regulation without using precious battery power.
Even with input voltage fluctuations as great as +10% or -25%, the output remains
constant, regardless of load.
ISOLATION
Electromagnetic and Radio Frequency Interference (EMI and RFI) can
damage semiconductors and have devastating effects on critical data. The CFR
UPS input is
totally isolated from the output to provide maximum protection from
this type of interference. Measured in decibels (dB) of attenuation, Alpha's CFR
achieves up to 120 dB common mode, and 60 dB normal mode.
EXTENDED BACKUP CAPABILITY
Alpha's EBP Series External Battery Packs allow you to greatly extend
your backup capabilities and power through long utility outages. Completely self-
contained and pre-wired, simply plug the EBP cabinet into your CFR and forget
about it. EBP Series External Battery Packs can also be ordered with an optional,
external charger to greatly reduce battery recharge times.
