AR-15 VOLTAGE REGULATOR / POWER CONDITIONER
5. Clean the AR-15 with a damp cloth only. Do not
use solvents or abrasive cleaners. Never pour
any liquid on or into the unit.
6. When left unused for a long period of time,
the power cord of the AR-15 should be un
-
plugged from the outlet.
7. The AR-15 should be serviced by qualified
service personnel when:
a. The power supply cord or the plug has
been frayed, kinked, or cut.
b. Objects have fallen or liquid has spilled
into the unit.
c. The AR-15 has been exposed to rain or
other moisture.
d. The AR-15 does not appear to operate
normally or exhibits a marked change in
performance.
e. The AR-15 has been dropped, or the
enclosure damaged.
8. The AR-15 requires that a safety ground be
present for proper operation. Any attempt to
operate the AR-15 without a safety ground
is considered improper operation and could
invalidate the warranty.
9. There are no user serviceable parts in the
AR-15. Refer servicing to qualified service
personnel only.
Voltage Regulation
Furman Voltage Regulators are intended to
protect sensitive electronic equipment from
problems caused by AC line voltage irregu-
larities—brownouts or overvoltages that can
cause audio tonal changes, digital equipment
malfunction (such as loss of MIDI programs or
other data), or, in extreme cases, permanent
damage. They accept input voltages over a
wide AC voltage range and convert them to a
steady, stable output at the desired standard
voltage, plus or minus five volts. Voltages ap-
proximately ±10% beyond that range may be
converted to usable levels, depending on the
requirements of the equipment. This stable
voltage protects equipment and allows optimal
performance. See graphs on the back page.
The AR-15 has eight outlets on the rear panel,
and one convenience outlet on the front panel.
All are functionally interchangeable. The outlets
are regulated, surge-suppressed, and linearly
filtered, making the unit a full-function power
conditioner. The AR-15 has no controls except
an on-off switch and the switch for the optional
rear rack light.
Note: The AR-15 is for use with AC voltage
only. DC voltages should never be applied to
them. Also, it does not change or regulate line
frequency. The output frequency will always be
the same as the incoming frequency.
SMP+ (series mode protection plus)
Traditional surge suppression rely on circuits
that “sacrifice” themselves when exposed to
multiple transient voltage spikes, requiring the
dismantling of your system, and repair of your
surge suppressor. Not so with SMP+. With
Furman’s SMP+, 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. While other designs offer
clamping voltages that are well above 330 Vpk,
Furman’s SMP+ clamps at 188 Vpk, (133 VAC
RMS). This unprecedented level of protection
is only available with Furman’s SMP+ technol-
ogy. Additionally, Furman’s trusted over-volt-
age circuitry protects against all too frequent
