Manual

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.
