Product Information - AMX UPC20 Plus Operation/Reference Manual

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.
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.

Momentary Power Relay contacts are closed only as long as a closure from input to

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.
