4-quadrant power supplies or 4-quadrant amplifiers are instruments that are capable to provide positive and negative output voltages as well as positive and negative output currents.
Laboratory power supplies are usually only single quadrant power sources. They are only able to deliver power with one single polarity, i.e. these instruments only work in one quadrant of the output voltage/ current diagram. Common amplifiers deliver voltages with both polarities, 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 two-quadrant devices.
The TOE 7620 series of 4-quadrant power supplies is able to work as a power sink as well as a power source with equal values of delivered or absorbed power. Thus a TOE 7620 series power supply is bipolar voltage and current source, and a current sink in one instrument and can replace a combination of single components. Frequent problems with the interaction of individual components and unexpected oscillations now belong to the past.
The input voltage range can be set to a range of ±5 V or ±10 V. Therefore no further external adaptation of the control voltage is necessary.
The DC offest voltage at the output can be adjusted to any value within the rated output voltage range. The external control voltage will be amplified and superimposed to the DC offset. This way the ripple voltage in an on-board supply system can easily be simulated.
The output impedance is adjustable in the range from 0 to 0.5 Urated / Irated.
All 4-quadrant power supplies of the TOE 7620 series can be equipped with the TOE 7620/103 option to deliver three times the rated current for approx. 3 ms.
A convenient feature is the output switch-off which allows immediate shut down of the output voltage and current when in the “Output OFF“ position. Additionally the output will be isolated!

Arbitrary power supplies for generation of any voltage and current characteristics with an output power from 160 W to 5200 W. With exceptionally versatile and user-friendly software.
In addition to many predefined standard impulses for the automotive and avionics industries, the arbitrary power supplies of the TOE 8805 to TOE 88165 series additionally offer the option for generating completely optional waveforms. You can thus generate test voltages which perhaps may only be defined in the future.
They also provide dips and drops, load dump impulses, and many versions of complex voltages.
A comprehensive library of curves typical in vehicles provides the user with a reliable and versatile test instrument.
A further operating mode of these extremely universal arbitrary units is the simulation of wiring system ripple as encountered in vehicles or aircraft. Ripples with frequencies from 20 Hz up to more than 70 kHz can be superimposed on the test curves or on a pure DC voltage.
All models starting with the TOE 8825 are of modular design and consist of an intelligent control unit and boosters connected in parallel.
In these extremely universal units, the major features of a high-speed power supply have been optimally combined with those of an arbitrary function generator.
The software included in the scope of delivery is extremely versatile, allows intuitive use, and permits generation of almost any waveforms within a very short time. Direct data importing from digital oscilloscopes and data recording equipment is also possible without problem.
Furthermore, the software has a library with standard curves from global vehicle manufacturers which is continuously updated.

The new Electronic Switch TOE 9260 is the first choice for generating micro interruptions in supply voltages. Conforms ideally to LV124/VW80000 Vehicle Electric System test standards.
Depending on the model, currents of up to 100 A can be switched at a rated voltage of up to 60 V.
- Rated voltage 60 V DC
- Rated current 50 A DC / 100 A DC
- Rise and fall time < 1 μs
- Discharge of circuit load
- 4 signal line switches
- Signal Generator Control (TTL level)
While testing vehicle power systems according to standards, it is necessary to momentarily interrupt supply voltages. This can easily be accomplished and executed with the Toellner Model TOE 9260 Micro Switch, operating between
Any voltage source of up to 60 V DC with approp¬riate current rating can be connected to the input.
Using an external signal generator, the current flow can be interrupted by switch “S-1” on demand. Discharging the load circuit can be accomplished by another internal switch “S-2” during the interruption process of the load current.
Four additional signal line switches (“S-3 thru “S-6”) enable precise switching and interruption of signal lines and control lines in any current flow direction. Control of these switches (“S-3” thru “S-6”) takes place synchronously with “S-1”.
