Operation
POWER switch
Set the POWER switch to ON.
The unit supplies DC power to the connected camera via
the CAMERA connector.
The unit outputs video camera signals and inputs sync
signal depending on the camera and the camera cable being
used.
For details, see "Connections" on pages 5 to 8.

POWER SUPPLY OPERATION DESCRIPTION
120 V AC (CMA-D2) or 100 to 240 V AC (CMA-D2CE)
is
rectified
by the bridge diode
(BRI)
and
smoothed
by the
electrolytic capacitor (C6).
|
And it 1s switched by the transistor (Ql), transformed by the
transformer (T1), rectified by the diode (D51) and smoothed by
the electrolytic capacitors (C51, C52), and it goes cut.
The shunt regulator (IC51) detects its output and it is fed back by
the photocoupler (PC1).
So the output voltage is regulated.
This
power
supply
has
the
overcurrent
protector
and
the
overvoltage protector for output.
The overcurrent protector controls the output current by detecting
the primary current when the output is in the overcurrent state.
The overvoltage protector is using the zener diode (ZD51) at the
output.
