Remote AC Power Controller
MODEL PowerPort
Owner’s Manual
About the PowerPort
Thank you for purchasing the Furman PowerPort Remote AC
Power Controller. By installing this PowerPort you will minimize
the risk of damage that can be caused by surges, faulty wiring
and even lightning strikes.
An individual PowerPort provides control, timing, monitoring,
and power conditioning capability for a single 20-amp circuit.
All critical circuit functions are governed by an internal
microprocessor.
PowerPorts may also be networked for total system control.
Multiple units can be daisy-chained via low-voltage wiring to
comprise the building blocks of a versatile, high
performance power conditioning and distribution system. A
PowerPort system can grow to any size, yet be conveniently
switched on and off with either maintained or momentary contact
switches using low voltage control lines.
PowerPorts offer the same power conditioning and EMI/RFI
filtering as Furman’s top-of-the-line PRO Series. A PowerPort will
handle a whopping 11,000 amperes of spike/surge current in any
mode, and will even keep itself from turning on if the voltage is
below 80 volts or above 140 volts. In addition, it has independent
turn-on and turn-off delays. Control wiring can be up to five miles
in length without performance degradation, based on using 24
AWG wire. Other features include:
• High reliability 25 amp relays.
• Incoming voltage is monitored for acceptable levels,
with marginal voltages causing flashing alerts and extreme
voltages causing protective shutdown.
• Manual mode allows delays to be overridden for system
diagnostics. Even in manual mode, power conditioning and
extreme voltage protection are still active.
• Turn-on and turn-off delay times are screwdriver-adjustable—
each can be set from 0 to 60 seconds.
• Front panel status LEDs indicate Protection OK, Ground OK,
Extreme Voltage Shutdown, Mains OK, Power Status (remains on
when an ON or OFF delay cycle is in progress, flashes when an
abnormal condition exists) and Outlet ON.
• Rear panel terminal barrier strip provides for a number of remote
control and LED monitoring options.
A PowerPort can be unobtrusively installed in the front or rear
of a rack (see back page). For permanent installations, the AC
cord may be removed and replaced with a standard 1/2" conduit
fitting.
Safety Information
To obtain best results from your Furman
PowerPort, please be sure to read this manual
carefully prior to connecting it to AC.
WARNING:
The PowerPort requires that a safety
ground be present for proper operation. Any attempt
to operate the PowerPort without a safety ground is
considered improper operation and could invalidate the
warranty.
Refer servicing to qualified personnel only.
For Warranty and Service information, see back page.
Remote Switches and LEDS
In the most basic configuration, only two Class 1 wires
and an SPST switch are needed to initiate the PowerPort’s
ON or OFF sequence. The switch may be either a
momentary or maintained-contact type, such as the Furman
RS-1 or RS-2 Remote System Control Panel. If another pair
of wires is used, an LED may also be installed at the remote
end to indicate that the power is on.
Maintained vs. Momentary Switching
Maintained switches, such as most toggle switches and
push-on/push-off button switches (including the Furman
RS-1), stay open until thrown, then stay closed until thrown
again. Momentary switches, usually pushbutton types like the
Furman RS-2, are normally open and stay closed only as long
as the button is pressed. An on-off switch of either kind may
be used to actuate the PowerPort’s remote operation.
Maintained switches are generally most convenient when
there is only one remote location. When more than one
switch location is required, momentary switches allow the
sequence to be started from any location.
PowerPorts come factory-set for maintained switch
operation. They may be easily converted to momentary switch
operation by moving a jumper on the circuit board:
1. Disconnect the unit from AC power.
2. Remove the four screws that secure the top cover.
3. Near the center of the circuit board there are two pairs of
terminals labeled J1 MOMENTARY, and J2 MAINTAINED. Slide
the jumper off of J2 and then slide it onto J1. (The functions
of the J3 and J4 terminals are described in “Shutdown/Force
Off Terminals” on the next page.)
4. Reattach the top cover.
The PowerPort is now set for momentary switch
operation.
