Power supply of a photomultiplier

Photomultiplier power supply with galvanically decoupled input and high-voltage output and with overloading and shorting protection is described. Output voltage is controlled within 0.9-2.2 kV limits, temporal instability for continuous operation 8h is no worse than 0.03%, temperature instability - 0.005%/deg C witin +15 - +45 deg C range. Pulsation voltage (double amplitude) at maximal power is ≤ 20 mV
