If you are using both PSXX circuit breakers and PSX-AR auto reversers on a layout make
sure the PSX-AR J1 input is taking power from the J2 DCC track output of the PSXX
When PSXX are used with PSX-AR, the PSX-AR trip rate must be equal to or less than the
trip rate of the PSXX. If PSXX trip rate = 2amps, then PSX-AR trip rate must be =/less than
2amps. Reference your PSX-AR manual for setting trip rate.
3. Input and Output connectors J1 and J2 are designed to use 12 AWG-22 AWG wire.
a. Turn the screw on the connector counter-clockwise while looking at the connector
opening
b. Make sure the wire clamp is at the bottom of the connector opening.
c. Insert wire you are connecting, turn the connector screw clockwise to tighten.
2.
When wiring more than one PSXX [PSXX-2, PSXX-3] insure all input/output polarities
are the same
3. If you are using a heavier bus wire such as 10 AWG, solder a short length of 12 or 14
AWG wire to your heavier bus to connect to the PSXX terminal.
4. We recommend rail drops to the track bus every 3-5 feet. Insufficient feeders can cause
your track voltage to be significantly lower than your booster output voltage.
5. The PSXX Circuit breaker is designed to operate by opening one side of the two input
leads when an overload is detected.
a. J1-1 and J1-3 are connected to J2-1 by a copper trace.
a. Any application where a common rail is used should connect the common rail to
these terminals.
b.
The connection from J1-2 and J1-4 to J2-2 is opened when the breaker trips or
is turned off.
1. Connect the two wires from the DCC Booster to the PSXX J1-1 & J1-2 INPUT terminal
2. When Power is applied to the PSXX, the D12 LED near the J1 Input and the D7 LED
near the J2 Output should be on.
