COMPACT BENCH–TOP TYPE
REGULATED DC POWER SUPPLY
C4720
The C4720 is a bench –top type multipurpose power supply
incorporating a high voltage power supply that provides
maximum output of +1.5kV for a photomultiplier tube and
constant voltage power supplies that provide 5V and 15V
for peripheral devices such as Hamamatsu photon counting
units. The four digit digital voltmeter on the front panel shows
the output value of high voltage with high accuracy.
lnformation furnished by HAMAMATSU is believed to be reliabIe. However, no responsibility is assumed for possibIe inaccuracies or ommissions. Specifications are
subject to change without notice. No patent right are granted to any of the circuits described herein.
