FEATURES
The C10423 is a compact power supply and signal processing circuit
developed to drive the high-sensitivity UV sensor "UV TRON R9454".
By using a double-sided printed circuit board we cut the area size to
half that of conventional drive circuits (C3704 series).
Since the high-voltage supply and signal processor are mounted on the
same circuit board, the C10423 can operate as a high-sensitivity UV
sensor just by connecting a UV TRON and supplying a low DC voltage.
The signal processing circuit cancels out background discharges
which may occur in the UV TRON due to natural excitation light (cos-
mic rays, solar UV rays, etc.). This minimizes erroneous detection so
the C10423 output signal can be used without additional filtering.
Combining the C10423 with a high-sensitivity "UV TRON R9454" (sold
separately) for use as a flame detector yields sensitivity capable of de-
tecting the flame from a cigarette lighter (flame length 25 mm) even at
distances up to 5 meters away.

The output pulse width can be extended up to about 10 s by add-
ing a capacitor to the circuit board.

Since the output impedance of this power supply is extremely
high, an ordinary voltmeter cannot be used. Use a voltmeter that
has an input impedance of more than 10 G
