2. If all of the LED’s on the voltmeter
flash, the input voltage is marginally
high. The PL-PRO’s outlets will remain
powered unless the incoming voltage rises
above the Extreme Voltage Shutdown cutoff
voltage of 270 – 280 volts (UK version:
255 – 260 V).
3. If none of the LED’s on the voltmeter are lit,
and the Extreme Voltages LED indicator is
illuminated, then the PL-PRO Series II has
shut down power to its outlets because the
input voltage is in excess of 280 volts (UK
version: 260 V).
Digital Voltmeter:
(PL-PRO DE II, PL-PRO PDE II, PM-PRO E II
and PM-PRO PE II)
Furman’s laboratory-precision AC digital
voltmeter continually measures incoming
voltages, with a typical tolerance of +/-1.5VAC.
It should be noted that the voltage is read at
the AC mains input. No adjustment should be
necessary on these units.
Digital Current Meter:
(PM-PRO E II and PM-PRO PE II)
Furman’s laboratory-precision AC digital
current meter continually measures the total
circuit AC load, with a typical tolerance of ±0.5
amp. Because these meters feature true RMS
technology, the current readings are accurate
regardless of load conditions (capacitive,
inductive or resistive).
NOTE: Your Series II Power Conditioner does
not compensate for high or low line voltage.
If you frequently move your rack to different
locations, derive power from generators, use
long extension cords, travel internationally, or
are in an area prone to brownouts, you may
benefit from the use of one of Furman’s AC
Line Voltage Regulators.
On/Off Circuit Breaker:
This 16 amp capacity magnetic circuit breaker
switch is specifically designed to stand up to
the enormous high inrush current demands
of many power amplifiers. Additionally, the
switch is shielded from accidental power
disconnection with a hinged cover.
Extreme Voltage Shutdown Indicator:
This LED is normally off. It monitors a hazard
common in the entertainment industry: wiring
faults – for example, accidental connection
to 380 VAC where 240VAC is expected. The
Series II SMP+ circuit senses voltages that
are so high that operation would be impossible
and shuts the power down before damage
can occur. Upon initially applying power to
these units, the Extreme Voltage indicator
LED will light if the input voltage is above the
extreme voltage cutoff, and power will not be
applied to the unit’s outlets. If the unit has been
operating with an acceptable input voltage and
subsequently that voltage exceeds 280V, it will
shut off power to the outlet and the Extreme
Voltage LED will light.
