Description

Floating high-voltage source with centre tap, continually adjustable or controllable via an external voltage, for electrostatic experiments, experiments on radioactivity, as well as operation of spectral tubes, gas discharge tubes and field-emission microscope. With built-in high-voltage proof transformer for tapping a heating voltage (6.3 V/2 A) for electron tubes. The integrated 2½ digit instrument permits display of the voltage present at any of the output sockets. Passive current limiting ensures that no dangerous contact voltages can occur.
