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 Polyfuse
TM
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".
