Marketing Information |
The AR-PRO AC Line Voltage Regulator is
intended to protect computer, audio, video and other electronic
equipment from problems caused by AC line voltage irregularities-- sags,
brownouts, or overvoltages that can cause sensitive digital equipment to
malfunction, or, in extreme cases, to sustain damage. It accepts single
phase input AC voltages anywhere within two capture ranges, 88 to 142 or
170 to 264 volts, and converts them to the North American standard 120
volts (or, if desired, 100V). Voltages outside the ranges may be
converted to usable levels, depending on how far out of range they are
and what is considered usable. For example, any voltage from 80 to 267
will be converted to 120V +9, -11.
The AR-PRO can handle loads totalling up to 30 amperes as long as the
input voltage is equal to or above 120V (low range) or 240V (high
range). For voltages below that level, its capacity must be derated at
approximately 250 mA per volt.
Because the AR-PRO requires no switching to discriminate between a
nominal 120V or a nominal 240V source, it can protect against a
catastrophic error in AC mains wiring (for example, in live performance
situations, where each act requires a special AC configuration,
accidental connection to 220V occurs surprisingly often). This feature
also makes the AR-PRO ideal as a component of a power distribution
scheme suitable for worldwide use, accommodating national voltages of
100, 120, 220, 240, or others with equal ease and without need for
readjustment.
The AR-PRO uses a design based on a 25-tap toroidal autoformer. The
toroidal design assures minimal leakage of stray magnetic fields and a
highly efficient, compact package. The AR-PRO's circuitry monitors the
incoming line voltage with each cycle. If a voltage change requires that
a different tap be selected, the new tap is electronically switched in
precisely at the zero-crossing, to avoid distorting the AC waveform. If
necessary, the AR-PRO can switch taps as often as once each cycle. Most
commercial voltage regulators using multiple-tapped transformers switch
taps with relays at uncontrolled times, thereby creating voltage spikes!
And unlike voltage regulators that employ ferro-resonant transformers,
the AR-PRO is not sensitive to small errors in line frequency, making it
ideal for use with generators.
The AR-PRO has twelve convenience outlets on its rear panel, and two on
the front panel. All outlets are regulated, spike-suppressed, and
filtered against RFI with a 3-pole filter. There are no controls except
a master circuit breaker, which serves as an on-off switch. Two
bar-graph meters each comprised of 21 LED's each indicate input voltage
and output current, while three other LED's indicate proper function
(i.e., that the output voltage is within ±5% of the selected voltage, or
above or below that range). One or more units may be turned on remotely,
either simultaneously or in sequence, with a simple low voltage switch
closure.
The AR-PRO is housed in a double space (3.5” high and 16” deep)
rack-mount chassis, and weighs only 50 lbs (23 kg). It is made of
extremely rugged heavy-gauge black powder-coated steel. Optional
adjustable rear rack ears (order part number RRM-2) allow it to be
secured in the rear for extra stability in mounting. It is supplied with
a mating female twist-lock connector ready to terminate your custom
supply cable. |
