1.0 Power Supply
1.1 Power Connector
The NCS-3230 Multi-Rx
TM
will operate with any well-filtered 10-14 VDC
power supply capable of providing at least 200mA continuous, 1A peak.
The required power connector is a 2.1mm ID, 5.5mm OD coaxial power
plug. One power connector is supplied in the accessory pack with the
Multi-Rx
TM
.
1.2 Polarity
The center pin of the coaxial power plug must be wired positive (+). If the
plug is wired backwards, the Multi-Rx
TM
will not operate due to reverse
polarity protection built into the unit.
CAUTION:
The Multi-Rx
TM
was designed to work with voltages between
10-14 VDC. Voltages higher than 15V will cause an internal fuse in the
Multi-Rx
TM
to open to protect certain components. (If the fuse opens, the
unit will need to be returned to NCS for out-of-warranty repair.) Most Wall
Power supplies on the market that are advertised as 12 VDC are not
regulated and may put out as much as 20 VDC when not connected to a
piece of equipment. The output voltage is reduced when powering
equipment depending on the current drawn by the equipment and the
internal resistance of the power supply. The internal resistance of the
power supply varies depending on manufacturer and model number.
If
you are going to use a Wall Power Supply be sure it's output voltage,
when connected to the Multi-Switcher, does not exceed 14 VDC.
The
NCS-1514 Wall Power Supply meets the requirements of the Multi-Rx.
