GENERAL INFORMATION
DESCRIPTION :
This simple AC/DC power source is designed specifically
for use in educational institutions. It can be used to demon-
strate the concept of alternating and non-alternating volt-
ages. It can also be used for simple experiments using
lamps, resistances, etc. The unit has been provided with
Voltmeter and Ammeter for AC / DC Voltage and current
readings
