UPC20+ Universal Power Controller

Installation

P1 Terminal Connections

Low voltage power (see the table below) for internal circuitry is provided from an on-board transformer,

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.

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.

P2 Terminal Connections

The table below defines the inputs and outputs for Terminal P2.

Control Mode

The table below defines the control mode functions for Inputs 1 and 2. TheUPC20+ Control Mode

Functions for Inputs 3 and 4 table on page 9 defines the control mode functions for Inputs 3 and 4.
