1. INTRODUCTION
1.1 The Alpha CFR
Congratulations on your purchase of one of the most advanced and intelligent
Controlled Ferroresonant-Uninterruptible Power Supplies (CFR-UPS) in the world! The
Alpha CFR is designed to keep your equipment operating, regardless of the condition
of your utility power. This means that your vital equipment will no longer be affected by
spikes, surges, sags, noise, brownouts, blackouts or other forms of electrical disturbances. Operation is as simple as plugging your equipment into the back of the UPS
and switching on the power.
The CFR provides you with a wide range of power management options using
your choice of interface devices. The Standard Interface Device displays vital UPS
operating parameters, including Alarms, and allows you to manually self-test the UPS.
The Intelligent Interface Device provides you with precise Voltage, Current and
Frequency information, plus maintains an on-going record of all Alarm and Line Failure
Events. As an active center of communication, your CFR can also be interfaced
directly to your computer system to inform you, and your users, of changes in status as
they occur.
With distribution networks and service centers located throughout the world,
Alpha Technologies is here to back you up. From your date of purchase, Alpha
provides complete technical support and prompt, reliable service to ensure that your
CFR-UPS provides you with a lifetime of reliable operation.
The Alpha CFR-UPS provides regulated, current-limited,
output with excellent isolation and noise attenuation.

1. INTRODUCTION
1.2 The CFR Advantage
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.
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.
Unlike many standby power systems which regulate output voltage
only when operating from their battery backup, the Alpha CFR UPS
constantly maintains +1% 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.
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
ference. Measured in decibels (dB) of attenuation, Alpha's CFR achieves up to 120
dB common mode, and 60 dB normal mode.
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.

is detected, the UPS lights a “Service” indicator. Self-test is extremely useful during
troubleshooting and maintenance.
PRECISE LOAD & OVERLOAD INFORMATION
The Alpha CFR provides vital load information to eliminate guess work associated with matching the appropriate load to your unit. The Alpha CFR displays the
existing load and, whenever the load exceeds the rated output, an "Overload"
indicator is illuminated.
The CFR UPS is equipped with a frequency sense circuit, along with a constant
slew frequency synchronization circuit, to provide trouble-free operation with most
standby generators.
Designed to meet or exceed the safety standards established by UL, CSA and
VDE, the Alpha CFR UPS is one of the safest, most reliable and versatile
uninterruptible power supplies available. Our commitment to safety and quality
engineering has not only established industry-wide safety standards, but has earned
