ELITE 20 PF OWNER’S MANUAL
1900 - 2300 Watts per Elite-20 PF employed.
The RMS current available before the circuit
breaker trips varies due to what is referred to
as a vector load. Simply put, the type of power
supplies or electronic circuits connected to
the Elite-20 PF will have an effect on its circuit
breakers perceived current load, and therefore,
when it will trip. Though the benets of
power factor correction far outweigh the small
reduction in continuous current draw, this must
be accounted for when constructing a large
system with high RMS current demands.
The total continuous current draw of most
electronic components is typically listed in
Watts by their AC input cord or AC connector.
Watt ratings are simply added to determine the
total system RMS current draw. It should also
be noted that the Elite-20 PF’s power correction
circuitry has no actual effect on the power drawn
from your utilities’ power meter. The Elite-20
PF draws a mere 12 Watts independent of other
components, so it may be left on at all times.
Retractable Front Panel Lights and
Dimmer Control
The Elite-20 PF includes a front panel mounted
dimmer control for the two retractable front
panel light tubes. The dimmer knob controls the
brightness of both light xtures. Turn it clockwise
to increase brightness; turn it counter-clockwise
to decrease brightness. When the lights tubes
are fully inserted ush to the front panel, the
light circuit is turned off via an internal micro-
switch. Whether the light tubes are retracted or
nearly ush with the front panel, there will be no
appreciable heat regardless of dimmer setting
due to the efciency of our full light spectrum
LED’s.
Soft Start - Continuous Use and Break-In Time
When power is rst applied to the Elite-20
PF, (the front panel breaker- power toggle
must be switched to the “on” position) the Soft
Start feature is activated. There is an audible
“clack” when the Elite-20 PF is rst turned on
or off. This sound is produced by the Soft Start
circuit’s 30 Amp relay engaging or disengaging.
There is virtually nothing in the Elite-20 PF’s
construction, design, or componentry to wear
over the life time of the product, and there is
no power draw from your electric service meter
aside from the LED power indicator, lamps, and
relay circuits. For this reason the Elite-20 PF
may be left with its power engaged permanently
at a cost of pennies per month. This is an
added benet, as many audio/videophiles
nd performance improves signicantly when
leaving low-powered components permanently
charged (turned on). In fact, this is true of the
Elite-20 PF. Though it will function awlessly
right from its shipping carton, the performance of
its circuit parts will improve after approximately
two weeks of continuous use or “break-in.”
AC Transient Voltage Surge
Suppression and Extreme Voltage
Shutdown
Extreme Voltage Shutdown Indicator:
This LED is normally off. It monitors AC wiring
faults – for example, accidental connection to an
open neutral from a 208 or 240VAC feed (this
is a common occurrence if the 20 Amp outlet
source is not a dedicated line, but instead has
been wired with a daisy-chained neutral from
a homes breaker box). The Series Multi-stage
Protection (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
