Another feature unique to Furman's SMP+ circuit is automatic Extreme
Voltage Shutdown (EVS) with a TVZ MOV. Extreme voltages are
statistically the most common, damaging AC event. The Extreme
Voltage Shutdown circuit automatically turns off the AC-5 / AC-0 E
when it is fed 37 volts [75VAC for the AC-0 E] or higher, protecting
itself and connected equipment from the extreme voltage. Only Furman
offers this advanced degree of protection.
INDICATORS
Extreme Voltage Shutdown Indicator
The AC Series SMP+ circuit senses voltages that are high enough to
cause damage to your components, and shuts the power down before
damage can occur.
The Extreme Voltage Shutdown LED is normally off. If an input voltage
in excess of 37VAC [75VAC for the AC-0 E] is sensed, either on
initial power-up or during normal operation, the AC-5 / AC-0 E will
shut off power and this indicator 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 first checking the source of the
problem, and perhaps changing the AC source.
Protection OK Indicator
Although the Furman SMP+ circuit assures protection from transient
voltage spikes and surges, nature has a way of occasionally creating
electrical forces that are beyond the capabilities of any TVSS device
to absorb without some degree of damage. In the rare instance that
this occurs, the green "Protection OK" LED indicator located on your
front panel will turn off. If this happens, some level of protection from
voltage surges will remain, but the Furman's clamping voltage rating will
be compromised. The unit must be returned to Furman Sound, or an
