2.6 Power Managers for Sub-Districts & AutoReversing
If you want the benefits of setting up
power districts on your layout but
you don’t need to add more power to run more trains, you can use a Power
Manager like the PM42 to set up sub-districts within booster power districts.
With a Power Manager you can separate the output of one or more boosters
into multiple sub-districts that can be set up as either auto-reversing or as smart
circuit breakers for short circuit management. For more information about this
option check our web site at www.digitrax.com.
2.7 Using AR1 for AutoReversing
If you have a single reversing section that doesn’t need its own booster, you
can use the AR1 single unit auto reverser to set up a reversing section.

Powering your DB210/DB220
The DB210 is for use with DC POWER input ONLY, MAXIMUM INPUT
8 AMPS, 24VDC, DO NOT Exceed 25VDC maximum Input. Minimum
Input 13.8VDC.
The DB220 is for use with DC POWER input ONLY, MAXIMUM INPUT
16 AMPS, 24VDC, DO NOT Exceed 25VDC maximum Input. Minimum
Input 13.8VDC.
Note: Grey terminal connectors are only rated for a Maximum of 8 Amps and
should only be used with compatible 8 Amp boosters and Command Stations.
The DB220 uses a special Black Connector that is rated for 16 Amps.
ONLY
BLACK CONNECTORS CAN BE USED WITH THE DB220.
There are many DC power supplies and power packs that can supply the input
power for the DB210/DB220. Most regular DC model railroad power packs
are not able to supply sufficient amperage to the DB210/DB220, because they
were designed to run only 1 or 2 locomotives in a DC blocked Common Rail
system. With Complete Train Control you’ll be running multiple locomotives
in Direct Home wired power districts so, you’ll need to provide more power to
each district.
It is recommended that when selecting a DC power supply the voltage should
slightly exceed the scale track voltage you plan to run by about approximately
1 to 2V DC, and should provide sufficient current to support the chosen 3/5/8
Amp limit setting. The DC input voltage should not exceed track scale voltage
by more than 3V. If the DC supply voltage exceeds track scale voltage by more
than 3V the DB210/DB220 will adjust to Safe Operation Mode see Section
4.10.4.
When connecting a DC power supply to an ADVANCED DB210/220 booster
the Po) power supply lead connects to pin7 terminal l 8A or +
16A, and the negative(-) lead connects to pin6 terminal labeled - 8A or -16A.
