| DESCRIPTION
The 15 amp
AR-15 delivers a stable 120 volts of AC power to protect equipment from problems
caused by AC line voltage irregularities such as sags, brownouts, or
overvoltages - all of which can cause sensitive electronic equipment to
malfunction or sustain damage. AR-15 accepts any input voltage from 97V to 141V
and transforms it to a constant 120V, ±5V. Voltages beyond that range may also
be converted to usable levels, depending on the range variance.
Additionally, the AR-15 is the only regulator that filters and purifies
AC power, reducing line noise and ensuring optimum performance. Not only will
your equipment perform better with Furman's advanced filtering technology, but
it will also be fully protected by our exclusive Series Mode Protection
circuitry (SMP). This circuit provides the highest level of power protection
available.
Many competitive voltage regulators use noise-inducing,
motorized transformer-based technology. This results in large, expensive, and
less reliable units which can not match the level of performance delivered by
the AR-15. Essentially, Furman's advanced technology allows us to offer superior
performance in a one rack space unit at a cost effective price point.
The
AR-15 circuitry monitors the incoming line voltage with each cycle, comparing it
to an extremely precise voltage reference, accurate to กพ0.15%. If a voltage
fluctuation requires that a different tap be selected, the new tap is switched
electronically at the zero-crossing, to avoid distorting the AC waveform. (Most
commercial voltage regulators using multiple-tapped transformers switch taps at
uncontrolled times, thereby creating voltage spikes, and often creating clicks
that can leak into the audio.) The design is not sensitive to small errors in
line frequency, making it ideal for use with generators.
The AR-15 has
eight outlets on the rear panel and one on the front panel. All outlets are
regulated, spike-suppressed, and filtered against RFI. There are no controls
except the on-off switch. A bar-graph meter comprised of 10 LED's indicates
input voltage, while another LED indicates "In Regulation" status (i.e. that the
output voltage is within ±5V of 120V).
LiFT (Linear Filtering
Technology) Unfortunately, traditional AC filter conditioners have been
designed for unrealistic laboratory conditions. Prior technologies, whether
multiple pole filter or conventional series mode, could actually harm audio and
video performance more than they help, due to the resonant peaking of their
antiquated, non-linear designs. Under certain conditions, these designs can
actually add more than 10 dB of noise to the incoming AC line! Worse still, lost
digital data, the need to re-boot digital pre-sets, or destroyed digital
converters are frequently caused by excessive voltage spikes and AC noise
contaminating the equipment ground. Furman's SMP with LiFT takes another
approach, ensuring optimal performance through linear filtering and no leakage
to ground.
SMP (Series Mode Protection) Furman's maintenance-free SMP
surge suppression virtually eliminates service calls. Traditional surge
suppression circuits "sacrifice" themselves when exposed to multiple transient
voltage spikes, requiring the dismantling of your system and repair of your
surge suppressor. With Furman's SMP, however, damaging transient voltages are
safely absorbed, clamped and dissipated. No sacrificed parts, no service calls,
no down time.
Unique to Furman's SMP is its unparalleled clamping
voltage. Unlike some series mode suppressors, Furman's maintenance free feature
is not at the expense of potential equipment failure! While other designs offer
clamping voltages that are well above 300Vpk, Furman's SMP clamps at 188Vpk, 133
VAC RMS, even when tested with multiple 6000Vpk - 3000 amp surges! This
unprecedented level of protection is only available with Furman's SMP
technology. Additionally, Furman's trusted over-voltage circuitry protects
against all too frequent accidental connections to 208 or 240VAC, by shutting
off the incoming power until the over voltage condition is
corrected.
