Positive Polarity Adjustable High Voltage Module for Photomultiplier Tube 1500V

New Revision of Adjustable HVPS DIY High Voltage Module for Photomultiplier Tube 150V - 1500V.
This power supply has positive adjustable high voltage output 150V - 1500V (under 10Meg. load) and can be used for DIY Photomultiplier Scintillators, Amateur PMT Projects or for powering Geiger tubes.
 
High Voltage can be adjusted manually with on-board potentiometer or through Digital SPI interface. You need to set the DIP-Switch to select desired controlling method.
 
Example control code for Arduino can be downloaded in Github repository.

This is regulated stabilized HVPS power supply for DIY hobby projects. The module can be used to power several Geiger tubes or PMT tube in gamma scintillation project.
 
Circuit uses PWM high frequency conversion of ~60KHz. It easy to filter the noise because of high conversion frequency. The board of the power supply has installed RC filter to reduce noise factor. 
 
5-Pin connector pinout:
GND - for external microcontroller ground reference
5V OUT - allows to power external low profile microcontroller
SDI - SPI data input
SCK - SPI clock input
CS - SPI Chip Select, Active -HIGH
 
DIP-Switch Selector: You must set just one of the illustrated dip-switch pre-sets.
DIGITAL: 1-ON ; 2-ON; 3-ON; 4-OFF; 5-OFF; 6-OFF
