(3) if all of the leds on the voltmeter
flash, the input voltage is marginally
high. Power to the Power factor
Pro’s outlets will remain on unless the
incoming voltage rises above the
extreme Voltage shutdown (eVs)
cut-off voltage (135 - 140 volts).
the Power factor Pro’s voltmeter has a basic
accuracy of plus or minus two volts, and
extreme cold or heat may cause an additional
one volt of error (four volts and two volts for
Power factor Pro e).
NOTE
: although the Power factor correction
will more than compensate for peak current
demands, the Power factor Pro does not
compensate for
sustained
high or low line
voltage. if you derive power from generators,
travel internationally, or are in an area prone
to extreme brownouts, you may benefit from
the use of one of furman’s aC line Voltage
regulators.
on/off rocker Switch:
this 15 amp capacity power switch is
specifically designed to stand up to the
enormous high inrush current demands placed
by many instrument amplifiers. Additionally, the
semi-transparent rocker lights when switched
to the “on” position.
extreme Voltage Shutdown (eVS) Indicator:
this led is normally off. it monitors a hazard
unfortunately common in the entertainment
industry: wiring faults – for example, accidental
connection to 220VaC where 120VaC is
expected, or an open neutral from a 208 or
240VaC feed. the Power factor Pro’s 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 be lit 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 then that
voltage goes above 135V, it will shut off power
to the outlet and the extreme Voltage led will
light.
note:
if the mains power is above the high
cutoff voltage and has caused the unit to
remove power from its outlets, it cannot restore
power without the operator manually turning
the unit off, then on again. avoid turning the
unit back on without checking the source of the
problem first, and perhaps changing the AC
source.
