High Voltage for PMT

Photomultiplier tubes (PMT) are usually used for detection of weak doses of light in various different applications such as Particle Detectors for Neutrons and Muons (in combination with scintillator materials), medical technologies, optical spectroscopy, electron microscopy and many more. iseg offers standard solutions for many PMT types as well a customer specific designed power supplies for many PMTs and applications.

High Voltage for PMT: iseg BPS series

The BPS is a small DC/DC converter which can be mounted and soldered on PCBs. The output voltage is controllable with either a potentiometer or an analog control voltage. The patented resonance converter technology and moulded metal box shielding guarantee lowest electromagnetic interference and low ripple and noise.

High Voltage for PMT: iseg CPS series

CPS modules are highly stable analog controlled high voltage power supplies. They are available as compact metal box or system capable in 3U Eurocassette standard. Modules of the CPS series can be used as standalone DC/DC converters, combined to multichannel AC/DC supply in a THQ series or integrated in a modular MMC system.The output voltage is controllable via analog interface with either a potentiometer (internal reference voltage) or an input analogue control voltage. To protect the connected load the modules are equipped with INHIBIT, current and voltage limits.

High Voltage for PMT: iseg DPS series

The DPS series includes high voltage power supply modules with output voltages up to 6 kV in a compact and easily mountable housing. The maximum power is 12 W, polarity is switchable. The HV output is finished by HV cable or by SHV connector. The version the supply and control voltages are connected either via a D-SUB 9 connector or H15 connector (3U cassette).

An internal reference voltage can be used to control the output voltage with help of an external potentiometer. Analog I/O is provided for remote monitoring and control. To protect connected loads hardware limits for voltage and current can be defined. Our patented resonance converter technology and the metal box shielding guarantee lowest EMI.
