Power source for all electrostatic experiments and for operating spectral and gas discharge tubes. The unit provides three continuously variable DC voltages isolated from ground. Two of the voltages are connected in series of 0 – 5 kV, giving a total voltage of 0 – 10 kV. Voltage polarity can be positive or negative. Digital 3-digit display and switchable to the desired socket with switching dials with LED marks the selected outlets.

Gas discharge tube can be operated without cables. The outputs are short circuit-proof and the selected current is limited to 3 mA for safety reasons. Designed to provide maximum protection to the user.

Output voltage: 0 to ±10 kV

Rated current: 0,1 mA
