HIGH AND LOW TENSION POWER SUPPLY UNIT

HIGH AND SUPPLY UNIT

 

multiple output ranges for  greater versatility

 

high tension output may be exeternally triggered

 

double electronic protection system for I and V

 

This power supply unit was designed especially for use in the educational loffering several fixed and variable output ranges , and able to withstand overloads due incorret use.

The 3-4 mA 0-5 kV output is guaranteed safe , while the  EHT output which is obtained by means of a controlled d.c. - d.c. converter has a current output limited to 1 mA and is therefore biologically harmless. The variable output are electronically protected against short-circuts of even Unlimited duration.

Techinical characteristics 
Power requirements 110/220 V a.c., 50-60 Hz
Absorption 100 W max
Output ranges - EHT 0-5 kV d.c., 3-4 mA, continuously adjustable, negative earth

- EHT 0-15 kV d.c., 1 mA, continuously adjustable, negative earth

- HT 0-300 V d.c., 60 mA, continuously adjustable, fully floating.

- LT 0-30 V d.c., 60 mA continuously adjustable, fully floating.

- 300 V d.c., 60 mA fixed, fully floating

- 6.3 V a.c. 2 A, fully floating

- 6.3 V a.c. 2 A, with earth

 

Protection elettronic on variable outputs, fuses on fixed outputs.
The outputs are completely independent and may be connected in series. The fully floating circuits may also be earthed or given a non-zero potential.

The EHT output may be truggered by and external low tension source (2-10 Vpp) which activates the converter to produce an EHT output in synchrony with the tension of the control generator (eg. on function generator). This is prticularly useful for the production of elettronical discharges with a preset frequency, for example, when plotting on spark paper.

The 6.3 V a.c. outputs and the RHT and HT outputs makes this power supply unit particularly useful with electronic tubes. Due to the continously available EHT output, this unit is also suitable for use with many of the items used in electrostatics, serving as a source for costant potential charges in place of the usual electrostatic generator.
