Getting Started
The PS2012 power supply is a heavy-duty unit designed to drive one or more
boosters in a DCC environment. It can also be used for high current applica-
tions in standard DC environment.
Controls and Connectors
Front panel controls and connectors provided on the front panel are:
On/Off Switch
DC Amperes output current meter
Scale selectable outputs for N, HO, or Large scale operation
Dual DC output connections
DC connectors - Figure 1 shows DC power-out connectors. Two pairs of bind-
ing posts are provided for ease of connection to multiple boosters. In addition
to the power on/off switch, the PS2012 has a selector switch for N scale, HO
scale, and G (or large scale) operation. The unit also has a built-in output cur-
rent meter for monitoring total layout current load.

Back panel controls and connections: The PS2012 comes with a 3 prong plug
(2 power and ground). This unit must be used with a properly grounded AC
receptacle. Input power is switch selectable and supports 115 or 230 volt oper-
ation. For 230 volt operation, please obtain from local sources the appropriate
power cord with an IEC type inlet plug. Please insure it is a grounded 3 wire
type cord constructed of 18 AWG wire and rated for at least 250 volts.
Installation
All secondary devices need to be properly fused on their power input leads
for their rated capacity. For example if you intend to use the PS2012 to drive
a 5 and an 8 amp booster, you must input fuse these devices for 5 and 8 amps
respectively A fuse in this case can be a traditional fuse, a circuit breaker, a
thermal fuse or a PolyfuseTM type self resetting limiter. The PS2012 can be
used with Digitrax's DCS100/200 series boosters, or with the Super Empire
Builder (DB150). The PS2012 can also be used to power other manufacturers
boosters provided the input fusing guideline above is followed.
Installation Considerations
Your PS2012 is overload protected. Should you experience a power supply
shutdown, please unplug the power supply, and allow at least 60 seconds for
the PS2012 to reset internally.
Ventilation. The rear fan and intake vents should be as unobstructed as possible
so as not to impede airflow. In particular, avoid placing objects within 2 inches
of the intake vents or exhausts of the fan itself.
The term "PolyFuse" is a registered trademark of the Wickmann company for a resettable overcurrent
protection device. Similar units made by Raychem Co. are called "Polyswitch" while those made by Bourns are called "MultiFuse".

Configuration
To connect the PS2012 to boosters and other 5 amp rated devices, use the ‘Y’
cable shown below:
Two ‘Y’ cables are required for 4 boosters at 5 amps. Additional ‘Y’ cables can
can ordered from your local dealer. The ‘Y’ cable part number is YC52
The final step is to properly set the front panel selector switch for your scale:
The ‘G’ setting configures the supply to output 23 volts at 12 amps max.
The ‘HO’ setting configures the supply to output 18 volts at 15 amps max.
The ‘N’ setting configures the supply to output 13.8 volts at 20 amps max.
