CIRCUIT DESCRIPTION :
The circuit uses a step down tranformer to provide step down
supply to a single phase variable autotransformer to obtain an
output voltage variable from 0 to 130VAC. This is followed by a
triple shielded isolation transformer which provides an output
voltage from 0-130VAC or 0-260VAC electrostatic and galvanic
isolation.
Multiple shielding technique reduces primary to secondary static
coupling to below 0.0005pF. The DC isolation is over 1000 M
Ohms.
