(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)
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
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.
