HV High Voltage Power Supply Kit for PMT Photomultiplier / Geiger tube 1500V max

Description

Adjustable HV High Voltage Power Supply 150V-1500V, positive output.
compatible with  DIY PMT / Photomultiplier Scintillation probes / can be used for Geiger tubes.
PCB Edition ver.2.0 Updated
HVPS output is regulated and filtered!
This power supply has positive adjustable high voltage output 150V - 1500V (under 100Meg. load) and can be used for DIY Photomultiplier Scintillators, Amateur PMT Projects or for powering Geiger tubes. The power supply is able to supply enough current even for several Geiger Tubes connected in parallel. Circuit based on TL494 IC.
It's recommended to install the power supply into shielded metal enclosure and add additional local RC filter 100K+10nF 2kV in point where you connect HV to a photomultiplier.

Compatible with DIY Scintillation Probes
Compatible with Geiger Tubes
Recommended load of the photomultplier probe divider: 50-120 Mega ohm
Input DC voltage: 12V
Input current: 15mA - 50mA
Topology: Boost TL494 PWM ~60KHz (easy to filter)
PCB dimensions: 65mm x 55mm
This is regulated stabilized HV power supply for DIY hobby projects. The module can be used to power several Geiger tubes or PMT tube in gamma scintillation project. The HV adjustment is done with potentiometer.
To get less noise on PMT tube signal I recommend to use high impedance tube divider of 80M-100M and
install the power supply board into separated and properly isolated metal enclosure (divider, enclosure and pulse AMP are not included).
Circuit uses PWM high frequency conversion of ~60KHz and it easy to filter the noise. The board of the power supply has installed RC filter.
