Adjustable high-voltage power supply (1961)

According to the manual, the Van der Heem type 8619 power supply can be used to supply a stabilised DC voltage of low source impedance, for powering experimental set-ups and calibration of instruments and numerous other applications in laboratory and industry.
The stabilized voltage supplied by the 8619 is continuously adjustable in three ranges: 0-35 V, 20-190 V and 180-350 V, at a current of 150 mA maximum on all ranges. Unstabilised voltages of 245 V, 375 V and 540 V are also available.
