Product description

4-quadrant power supplies or 4-quadrant amplifiers
are electronic modules which generate
both positive and negative voltages, and which
can also deliver and receive positive and negative
currents.

 

They can therefore be used as a source or sink.

 

Power supplies for laboratory use are mostly
only power sources. They are only able to deliver
power with one single polarity, i.e. these
instruments only work in one quadrant of the
voltage/current diagram.

 

Common amplifiers deliver voltages with both
priorities, but are generally unable to absorb
power values in a range comparable to that
which they are able to deliver.

 

They therefore mainly work as 2-quadrant instruments.

 

All four-quadrant power supplies of the TOE
7621 series are additionally able to absorb power
with both priorities corresponding to the
delivered powers.

 

A 4-quadrant power supply of the TOE 7621
series is thus a bipolar voltage and current
source as well as a current sink in one instrument.

 

Use as a bipolar power amplifier is also
possible.
