The E30 laboratory bench power supplies each offer a wide choice of voltage
and current ranges selected by means of a push button switch. The E30/1 provides
a
stabilised
output of 0 to 30 volts at 0.5 amps or O to 15 volts at 1 amp. The E30/2
provides the same ranges but twice the current and the ET30/2 is a twin output
version of the E30/2.
A push
button switch selects
the
required meter
scale to
display either voltage
or
current
and a similar switch puts the unit on or off. Coarse and fine
potentiometers
provide precise control over the continuously variable output.
The units are protected against progressive and sudden overloads by electronic
current limiting preset at 110% of the maximum current on the range employed. In
operation, this circuit limits the current that may be drawn from the unit. With
progressive overload the voltage output falls while the current remains approX
imately constant. On removal of overload the output will reset to its original voltage.
Being low cost, compact units extremely simple to operate and protected against
accidental short circuit, the E30 power supplies are the ideal choice for both indus
trial and educational laboratories, especially those with rather limited financial
budgets.
