• The unit has been dropped, or the enclosure has been damaged.
9. Your P-3600 AR G requires that a safety ground be present for proper operation. Any attempt to operate the unit without a safety
ground is considered improper operation and could invalidate the warranty.
10. Do not attempt to service your P-3600 AR G beyond what is described in this manual. All other servicing should be referred to
qualified service personnel.
P-3600 AR G Limitations
AC power is, to some extent, unpredictable. The available voltage may vary from place to place and from moment to moment. The
waveform may not be a perfect sine wave, and high or low frequency noise may be present. AC power also varies from country to
country in terms of voltage and frequency. The P-3600 AR G is a one-of-a-kind solution that will eliminate many of the problems
these issues may cause. However, you should be aware that there are certain things the P-3600 AR G cannot do. These include, but
are not limited to:
• Protecting from complete loss of power (blackouts).
• Performing frequency conversion to 60 Hz.
• Isolating ungrounded equipment.
• Handling multiple-phase power.

FEATURE DEFINITIONS
True RMS Voltage Regulation Technology
True RMS Voltage Regulation within the P-3600 AR G is designed around an ultra-low noise ten-tap toroidal autoformer. A micro-
processor monitors the incoming RMS voltage with each cycle, measuring the phase angle in time with the advancing cycle. Most
commercial voltage regulators using multiple-tapped transformers switch taps at uncontrolled times. This creates voltage spikes
and clicks that can leak into audio. When a voltage fluctuation requires correction by the P-3600 AR G, True RMS Voltage Regulation
advances a new tap with less stress and in turn avoids distortion to the AC waveform. Hysteresis in the P-3600 AR G circuits avoids
the unnecessary switching back and forth between the adjacent taps (or "chatter") found in many commercial voltage regulators. If
necessary, True RMS Voltage Regulation technology can switch taps as often as twice each AC cycle and do so with a shorter recov-
ery time than a commercial voltage regulator. In addition and unlike voltage regulators that employ ferroresonant transformers, the
P-3600 AR G is not sensitive to small errors in line frequency, making the unit ideal for generator use. Furthermore, the autoform-
er's toroidal design assures minimal leakage of stray magnetic fields.
The P-3600 AR G has a low range capability of 88VAC to 134VAC and a high range capability of 170VAC to 264VAC. There is no need
to select the range. The P-3600 AR G automatically recognizes a useable voltage and immediately begins to regulate. This impres-
sive capture range ensures a 120VAC output. In order to provide the regulated AC voltage, the P-3600 AR G has eight outlets on the
