Power Supply Block
The above figure shows the flow to supply power.
There are two ways to supply power to the camera. One is the POE power feed via the LAN cable and the other is the power feed
from the AC adaptor.
The POE power feed is described in SECTION 4.8.
[Power supply circuit on the IO board]
• The DC powers of +12 V and +3.3 V are generated on the IO board.
• The +12 V power is supplied by the AC adaptor or POE circuit mounted on the IO board. This +12 V power is used on the follow-
ing boards:
- IO board : +3.3 V DC-DC converter circuit and output terminal of the IO terminal (CN507) .
- Main board : Power supply to drive the PAN motor drive driver, and DC-DC converter circuit for +5.6 V that is supplied to the
camera unit.
- TILT board : Power supply to drive the TILT motor drive driver.
• The +3.3 V power is generated from the +12 V power in the DC-DC converter circuit (IC504). It is used on the following boards:
- IO board : Audio circuit and IO terminal unit
- Main board : All of the +3.3 V power supply
[Power supply circuit on the Main board]
• On the CPU board, the +1.2 V power used in the circuits internal to the CPU (IC101) is generated in the regulator (IC603). The
+5.6V power is generated from the +12 V power in the DC-DC converter circuit (IC609) and it is supplied to the Video board via
the TILT board.
[Power supply circuit on the TILT board]
• On the TILT board, the +12 V power which is supplied from the IO board via the Main board is used on the following boards:
- TILT board : Power supply to the TILT motor drive driver
[Power supply circuit on the VIDEO board]
On the VIDEO board, +5.0V in the regulator (IC206) and +3.1 V in the DC-DC converter circuit (IC204) are generated from the
+5.6 V power supplied from the Main board.
+5.0 V and +3.1 V on the Video board is supplied to the Lens board,.
• The +3.1 V power is used on the following boards:
- VIDEO board: All IC of the +3 V
- LENS board : Power supply to the DC converter (IC302) of the IRIS control
• The +5.0V powers are used on the following boards:
- VIDEO board: Power supply to the MOS SENSOR (IC201) and the TG/SG/CDS (IC 202)
[Power supply circuit on the Lens board]
• On the Lens board, +3.3 V in the regulator (IC208) is generated from the +5.6 V power supplied from the VIDEO board. The +12
V power is used on the following boards:
The +3.3 V power is used on the following boards used on the following boards:
- Lens board : Power supply to the ZOOM motor driver (IC303)
