OPERATING VOLTAGE: (100Vac to 240Vac or 127 to 370Vdc)
The PSC Power Star has a "universal" input voltage and can even be operated
from high voltage DC current. This design was chosen to facilitate the Power
Star operating worldwide without having to be adjusted. Simply plug it into a
properly wired outlet and you are ready to go.
AC LINE SAFETY:
Electrical safety codes require that electrical equipment be properly grounded for
operator safety. Many electrical outlets have been mis-wired with hot and
neutrals reversed as well as having missing grounds. This is especially true on
film sets where all power lines are portable and neutrals get kicked out time and
time again. For your own safety and for the good of your equipment, you should
test any AC line before connecting to it. This can be done by using a small, low
cost line checker available at most hardware stores. These checkers look like an
AC plug with three or four lights on them that indicate when the AC outlet is wired
correctly.
OUTPUT OVERLOAD PROTECTION:
The PSC Power Star is equipped with Raychem Polyfuses that automatically
reset to protect the outputs of the Power Star and also to provide a degree of
protection to your equipment. These solid state devices act like ordinary fuses or
circuit breakers. They interrupt the flow of dangerously high electrical current in
the case of a fault condition in the equipment being powered. The PSC Power
Star contains Polyfuses on its battery input and on all 10 outputs. The 10
separate Polyfuses that protect the 10 output connectors are monitored
separately.
The front panel of the PSC Power Star has 20 LEDs (10 green and 10 Yellow)
that provide a convenient means to monitor for proper operation. Under normal
operation, all 10 of the GREEN LEDs should be lit. This indicates that there are
no faults on any of the 10 outputs. If any one of the GREEN LEDs is off and the
corresponding YELLOW LED is lit, this indicates that this particular output
connection Polyfuse has tripped. This is a fault condition that must be corrected
immediately. By noticing which YELLOW LED is lit, you can easily know which
piece of equipment is having a problem. Simply put, Green is Good, Yellow is
Bad!
Because each of the individual outputs is individually polyfuse protected, if any
one piece of your equipment has a fault, the rest of your sound package will
continue to operate. These Polyfuses will only reset after the fault has been
removed and the Polyfuse allowed time to cool down (approximately 30
