DESCRIPTION:
The PSC Cart Power system is designed to supply 12Vdc from any AC outlet
and distribute is in a low noise manor. Each of the six outputs contain dedicated
EMI/RFI filters to reduce the chance of inter-modulation noise. In addition thecart power may be used to distribute power from your pelican style battery boxes.
USE:The PSC Cart Power is designed for use in powering your entire digital audio
recording package. Each of the Cart Power’s six, 4 pin female XLR output
connectors provide 12Vdc. You can either connect it to any 12V-battery packand use it as a power distribution network or plug it into AC and use it a power
supply. Both functions can also be used at the same time to create a uninteruptable power supply. You will primarily being operating off of AC, but if theAC goes out, the Cart Power will automatically power your equipment from yourbattery. Please note that the Cart Power does not provide a charge function foryour batteries.
OUTPUT OVERLOAD PROTECTION:
The PSC Cart Power is equipped with a Raychem Polyswitch automatic resettable fuse to protect the outputs of the Cart Power. 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 beingpowered. The Polyswitch will only reset after the fault has been removed and thePolyswitch allowed time to cool down (approximately 30 seconds). The
Polyswitch requires no manual resetting or replacement eliminating the need tocarry spare fuses in the field. Please note that the Polyswitch should not trip
during normal use of the Cart Power! If you experience tripping of this device on
any continuing basis, something is wrong and a qualified technician should checkyour equipment and cables immediately. When the Polyswitch has tripped, thefront panel mounted green LED will go out.

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.
It is highly recommended that you have your cables built by qualified personnel
and tested prior to use with your Cart Power. All power cables should be clearlylabeled on both ends as to what they are to be connected to. For example, label
one end “Cart Power” 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 carefulconnections. Poorly constructed and/or labeled cables can result in equipment
damage! Please also make sure that the devices you wish to operate from theCart Power are designed to operate on 12Vdc. The Cart Power does not supply
other voltages.
