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 multiturn potentiometer, please rotate is very slowly for the correct responseof the response circuit.
To avoid noise on PMT tube signal I recommend to use high impedance tube divider of 80M-100M and install the power supply boardinto separated and properly isolated metal enclosure (divider, enclosure and pulse AMP are not included).
Electrical circuit is based on DIP through-hole components. It has PIC MICROCHIP microprocessor that control and stabilize HV output. All others parts are easy to replace if you have problem. I include electrical circuit in the package. Just be careful about battery connection polarity and keep VDD voltage between recommended values of 4.8V-5.5V. The circuit has RC filter for PMT - 1uF capacitors and 3pcs 1M resistors.
