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.
