12V DC Power Output
The LCD330 has a useful 12V DC power output for powering
12V CCTV cameras and equipment. The LDC330 can provide
12V DC power up to a maximum current of 600mA.
Powering Cameras With The LCD330
Connect the narrow end of the supplied 12V DC power cable
to the ‘
DC 12V OUTPUT
’ of the LCD330. The standard 2.1mm
DC plug is then connected to the CCTV camera.
The locations of the LCD330’s connections are highlighted on
page 4
. All of the accessories supplied with the test monitor
are displayed on
page 5
.
Note:
Only use LCD330’s power output to power 12V DC
cameras and equipment.
Attempting to power devices which draw more than
600mA will automatically trigger the LCD330’s limiter
and power output will be stopped.
Do not connect the 12V DC output to the LCD330’s 9V
DC input as this may damage the unit.
