Introduction
This CCD video camera produces fully interlaced monochrome
television pictures, according to the CCIR standard.
The high light sensitivity of the camera means that it can even be
used very effectively under twilight conditions. The camera is also
sensitive to infrared light. It accepts a wide range of different supply
voltages, AC as well as DC. If an AC power source is used the
camera is automatically iine-locked.
Connecting the camera
Power supply
The camera must be powered by using a separate, galvanically
isolated, AC or DC power supply unit. The AC input voltage may
vary from 12V to 28V (50Hz). The DC input voltage may vary from
10V to 39V. Use a power supply which meets the requirements for
SELV service, according to DIN/VDE 0860/05.89 or EN 60742 only.
The power supply is connected to the camera via a three pole
screw block. The three entry ports for the wiring are on the rear of
the unit. Access to the fixing screws is gained via three holes on the
underside of the unit.
Connect the power leads to (D) and (E), fig. 1.
For DC supply: (D) is - and (E) is + voltage. An extra safety ground
connection is provided, (F) fig. 1, to connect the camera to ground
potential. The maximum voltage between the supply inputs (D) and
(E) and the safety ground (F) must be less than 50 Volt.
The camera itself is galvanically isolated which makes a system with
more than one camera not susceptible to ground loop problems.
