The stabilized power supply type E.350 provides a d.c. output variable from 0 to
350V at a maximum current of 100mA and two separate unstabilized a.c. supplies
suitable for valve heaters.
The output voltage of the unit is covered in seven switched ranges each of 50V with
continuous adjustment over each range by means of a fine control. Current and
voltage monitoring facilities are provided by a milliammeter and a voltmeter fitted
to the front panel. The output voltage is monitored before the H.T. switch so al
lowing the voltage to be set before switching the supply to the equipment. The
outout is 'floating' but either terminal may be connected to chassis using the front
panel earth terminal.
Overload and short circuit protection is provided to protect the power unit and ap
paratus being supplied. The protection circuit automatically resets when the over
load is removed.
These sound, reliable units have been manufactured in quantity for many years and
have proved popular for both industrial and educational applications.
