The Heinzinger PNC 600-300 (600V, 300mA) is not typically required for SiPM-based detectors, which operate at much lower voltages. Berkeley Nucleonics recommends the following Heinzinger power supplies matched to specific detector configurations: for SiPM detectors with integrated electronics (-E3 option), use the PTN 16-10 (0-16V, 0-10A) — these detectors require 5V to 16V at 2-20mA; for SiPM detectors without integrated electronics, use the PTN 65-2 (0-65V, 0-2A) — these require approximately 40-45V at 2-20mA; for PMT-based detectors, use the PNC 1500-40 (0-1500V, 0-40mA) — PMTs require 500-1500V at 2-20mA.
