iseg PHQ modules are developed for a direct HV supply of modern photo multiplier tubes (PMT) with the high voltage power supply integrated in the PMT socket. Advantages of PMTintegrated power supplies are:

    no HV cabling or connectors necessary no separate HV supply needed small form factor increase of reliability power dissipation reduced by factor 10 and more high temperature stability and thermal balance


-    DC/DC HV supply compactly integrated in PMT socket

-    low ripple and noise, low EMI

-    low power consumption

-    high linearity even at high pulse load and rates by stabilized dynode voltages

-    control- and monitor capabilities

-    safe anode current limitation for PMT protection

-    multichannel capable in MMP system

-    custom design on all kinds of PMTs
