of the various voltages and supply up to approximately 150 watts of total output
power when connected to AC only.
OUTPUT OVERLOAD PROTECTION:
The PSC PowerMax is equipped with Raychem Polyswitch automatically
resetable fuses to protect the outputs of the PowerMax.
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.
A front panel "Fault" LED will light up when a
particular Polyswitch has been tripped. For example, if the 12Vdc output is
overloaded, the Polyswitch that protects the 12Vdc output will trip and the "12V
Fault" LED will light up. The Polyswitch will only reset after the fault has been
removed and the Polyswitch allowed time to cool down (approximately 30
seconds).
The Polyswitch requires no manual resetting or replacement
eliminating the need to carry spare fuses in the field. Please note that these
output protection devices should not trip during normal use of the PowerMax! If
you experience tripping of these devices on any continuing basis, something is
wrong and a qualified technician should check your equipment and cables
immediately.
CABLES:
PSC recommends that you use only two conductor, unshielded 16AWG power
cable for power distribution. Shielded cable is not recommended as the shield
may cause short circuits between adjacent pins on the connectors.
NOTE: Use only the pins required for the correct voltage to operate your specific
piece of equipment! For example, if your RDAT recorder requires 12Vdc to
operate, then you should only connect pins 1 (ground) and pin 4 (12Vdc). In this
case you should not use pins 2 (6Vdc) or pin 3 (18Vdc) as these voltages are not
required and could potentially damage your equipment.
Many pieces of
equipment use pins 2 and 3 for other functions such as battery charging and
there are no industry standards for the use of these pins. Their use may not be
compatible with the PowerMax. Remember, use only 2-conductor cable and wire
only 2 pins on your connectors!
It is highly recommended that you have your cables built by qualified personnel
and tested prior to use with your PowerMax. All power cables should be clearly
labeled on both ends as to what they are to be connected to. For example, label
one end "PowerMax" and the other end "Fostex PD6". This will help prevent
inadvertently connecting the cables to the wrong piece of equipment. We cannot
stress enough the importance of good quality power cables and careful
connections. Poorly constructed and/or labeled cables can result in equipment
damage!
