UPC20+ Universal Power Controller

Product Information

The UPC20+ Universal Power Control is a dual 20 Amp AC power and motor controller designed
for conduit installation. The UPC20+ is housed in a compact metal wall-mount enclosure and is
configurable for a wide variety of power and motor control modes. Low voltage contact-closures,
open collector inputs or serial data from an AMX IR receiver enable control by simple wall panels,
remote systems, or hand-held transmitters. A test switch with an LED indicator for each relay is
provided for local control and status indication.
Using Motor Control mode, the UPC20+ output alternates between two relays, providing a brief
pause in-between relay contacts, to protect the motor. A timing adjustment potentiometer is user
adjustable for automatic release of the relays. (The range is 0 to 90 seconds). 1-, 2-, and 3- button
control modes are selectable.
In Power Control mode, the UPC20+ provides power control for two independent circuits with a
combined total load of 20 Amps. Single-button momentary/latching and 2-button latching modes
are selectable.
Momentary Power Relay contacts are closed only as long as a closure from input to
common is maintained.
Product Information
Latching Power Relay contacts are toggled (from open to closed and closed to open)
each time a closure from input to common is momentarily pulsed.
All functions and capabilities of the UPC20+ (including information on high voltage wiring, low
voltage wiring, and DIP switch settings) are described on a sticker installed inside the enclosure.
FIG. 1 shows the UPC20+ (inside view).
The UPC20+ will work the NXC-I/O10 input/output control card.

Control Options Modes

If UPC20+ is powered up when changes are made to Dip Switch settings, then power must be cycled before changes can take effect.

Motor Control mode

The table list options and connections for motor control. DIP switch settings provide 1, 2 or 3
button remote control contact arrangements. This mode is typically used for screen and drape motor
control.
In motor control mode, only one power relay (motor) can be energized at a time. When switching
from one direction to another, the first motor is automatically turned off and a half-second delay is
inserted before the other motor will turn on.
Once a motor is turned on, it will automatically be turned off after the amount of time determined
by the motor time delay potentiometer, R8. Delay time can range from 0 to 90 seconds. It is
typically set to allow direction limit switches to operate, or to reach the desired position.
Motor Control Mode DIP Switch S2 Positions
1 2 3 4 Control Mode
On On Off On Single button
Off Off Off On 2-button
Off On Off On Momentary On/Off
Single Button Mode operates with one pushbutton in a sequence: Up, Stop, Down, Stop
and so on for each successive button press.
Two/Three Button Mode operates with two pushbuttons, one for Up and one for Down.
Momentary On/Off operates only when the button is pressed.

Remote Sensor Control mode

The UPC20+ can also be controlled via the serial output from an AMX IR sensor. Remote sensor
mode is selected by setting jumper JP1 to the "Remote" position (jumper on the left 2 pins), as
shown in FIG. 3. (The jumper must be in position when power is applied to the UPC20+).

If motors of any kind are used, do not set to a Power Control mode. When a Power Control mode is selected, both relays can be on at the same time. Motors can be severely damaged if this happens.
osure
When controlled by a remote sensor, the UPC20+ is in 2, 3-button timer motor control mode. When
the timing potentiometer R8 adjusted to zero ohms (no time delay), the remote sensor provides
momentary control.
A 3-bit code (radio code) set on DIP switch S2 associates an AMX handheld remote control with a
UPC20+. This allows up to 8 UPC20+ and IR sensors to be used in the same room without
interfering with one another. It is possible to control 2 separate UPC20+'s with one handheld
remote control. The 4th switch of DIP switch S2 on the PCB selects between the two UPC20+'s.
The table below lists the results of the 16 possible DIP switch selections in remote sensor mode.

Installation

P1 Terminal Connections

Low voltage power (see the table below) for internal circuitry is provided from an on-board
transformer, powered by an external 120 or 240 VAC source. An onboard switch is used to select
input voltage. When using the UPC20+ for 277 VAC control, the on-board internal circuitry is
powered by a separate 120/240 VAC line, or from an optional 12 VDC power supply.
P1 Terminal Connections
Terminal Input/Output Function
1 Output Load 1 out
2 Input Line 1 in
3 Output Load 2 out
4 Input Line 2 in
5 Input Neutral to transformer on PCB which supplies low voltage
6 Input Line to transformer on PCB which supplies low voltage
Installation
K1 and K2 are the power and motor control relay connections to P1 terminals 1 and 2, 3 and 4,
respectively. Each relay is capable of switching the following loads:
Resistive Load 20 Amps at 120/240 VAC
Fluorescent Ballast 6 Amps at 277 VAC
Inductive Load 1 HP
The maximum total combined current through both relays is 20 Amps. There are two 12-gauge
jumpers that are wired to supply board power at 120/240 VAC, and to connect the common
terminals of the relays. The jumpers are removed as needed according to the wiring options
selected.
