Furman PS-PRO Professional Rack Mount Power Conditioner
SUMMARY - Furman ps-pro
Rack Mount Power Conditioner
The PRO Series are
Furman’s top-of-the-line power conditioners. They provide the most complete
and comprehensive protection from power line-related transient voltages,
noise, and wiring faults available. Their many special features were
designed specifically to provide maximum protection from the type of hazards
faced by delicate digital pro audio and video equipment. Power line
disturbances are real, and they are inevitable. According to Consumer
Reports (November, 1994), “One significant surge a day is the norm.
High-exposure areas may experience perhaps a hundred smallish spikes a day.”
Proper protection is essential for costly equipment, even more so if it is
frequently moved from location to location. But there is a wide range of
differences in the performance available from the protection products
available. What sets the PRO Series apart from other conditioners is the
quantity, quality, and configuration of the suppression devices used. These
include MOV’s, gas discharge tubes, fast-blow fuses, and high voltage
inductors and capacitors. This unique combination can safely absorb and
dissipate large spikes from nearby lightning strikes and other sources (up
to 11,000 amps across any wiring mode — line-neutral, line ground, or
neutral-ground), as well as highly attenuate audible high frequency noise.
Precise high-inrush magnetic circuit breakers avoid the false tripping often
encountered with large reactive loads like power amps.
An additional feature,
Extreme Voltage Shutdown, fights a hazard particularly common in the
entertainment industry: wiring faults — for example, accidental connection
to 220V. It senses voltages that are so high or low that operation would be
impossible (under 80V or over 140V) and shuts the power down before damage
can occur. LED status indicators (“Protection OK” and “Ground OK”) monitor
the integrity of the protection devices and grounding, and report if the
protection is compromised.
DETAILED
SPECS - furman pspro professional power conditioner
The Power
Conditioners shall mount in a standard 19" rack, and shall occupy one rack
unit (13/4") of rack space. There shall be at least eight switched outlets
supplying conditioned power on the rear panel and one unswitched outlet on
the front panel, with a front panel-mounted 20 amp, high inrush magnetic
circuit breaker rated for use as a master switch. No outlet shall receive
power if the mains voltage is “extreme” (defined as under 80V or over 140V).
Spikes shall be clamped to no more than 200 V peak in any mode (line to
neutral, neutral to ground, or line to ground). MOV’s for spike absorption
shall be redundant in each mode, placed across the lines on both sides of
the RF filter, and an additional device such as a gas discharge tube shall
be placed across the hotneutral mode to absorb spike remnants. Response time
shall not exceed 1 nanosecond.
The unit shall absorb a surge current of up
to 11,000 amperes across any mode for 10 ms without damage. RF noise
attenuation shall exceed 40 dB in both differential and common modes from 1
to 200 MHz. The AC cord shall be 12 AWG and ten feet long. Where provided,
voltmeters shall read from 90 to 128 volts in steps of two volts, and shall
indicate marginal voltages with different, easily recognizable flashing
patterns for below- and above-scale conditions. Ammeters shall read from 0
to 20 amps, in steps of two amps, and shall respond to RMS current. The
meter segments shall be color coded, and of sufficient brightness to be
readable in a dark area from a distance of 20 feet. The meters shall read
whenever the unit is plugged into the AC power line. Where rack lights are
included, a dimmer
control shall be provided, and the lights shall turn off when pushed in. The
units shall be the Furman PRO-Series Power Conditioners.
Three Year
Warranty
The Furman
PRO-Series is protected by a three year limited warranty covering defects in
materials and workmanship
