Automatic calibration
Fast and convenient calibration of all output parameters is possible externally within a few minutes without having to adjust any trimmers or make any interventions in the device. This “Autocalibration“ can be carried out simply using the control elements or with computer support within a test system. An autocalibration function provides significant advantages, particularly when considering the increasing importance of regular calibration intervals as a result of quality assurance systems.
Voltage source, current source and automatic power controDepending on the set values for voltage, current and power, each power supply can be operated, depending on the load conditions, as a constant voltage source, constant current source, or as a source with a constant output power.

Autoranging
The TOELLNER TOE 8871 and TOE 8872 series are extremely rugged highperformance power supplies with autoranging up to 1500 W.
Just one unit of this series provides what otherwise has to be covered by several powerful power supplies of different voltage/ current versions: low voltage range with increased current, extended upper voltage range with low current. This is easy to understand using the example of the TOE 8872-40: the instrument delivers 40 V or 100 A. For a square characteristic, either a 4 kW unit with 3-phase connection or two single units with different voltage/current versions would be required.
Extremely quietThe intelligent, thermostatically controlled fan technology with integrated, extremely quiet fan means that the units are extremely suitable for laboratory workstations. Optimum cooling of the units is thus provided in addition, resulting in an extension of the service life on the one hand and guaranteeing of a high endurance even under extreme load conditions on the other.
Brief load currentWith the TOE 8872-40 and TOE 8872- 60 models, the TOE 8871/022 option allows a brief increase in the output current by approx. 50 %. Thus approx. 150 A or 100 A can be drawn for 20 ms.
High regulation rateDie hervorragende hohe Regelgeschwindigkeit macht die Geräte zu einem Meisterwerk ihrer Klasse.
The superb regulation rate makes these units the masters in their class. In contrast to other switched-mode power supplies, the TOE 8870 series permits generation of voltage/current curves at high speed without reducing the output capacitance.
This would result in overvoltages and current peaks at the output and destroy the device-under-test. A wide range of curves can therefore be generated via the analog control, e.g. as required in the standards of the automotive industry.
Simulation of the starting curve (cranking) of a vehicle is thus possible without problem.
Extremely short rise and fall times of the output voltage – also at no-load (TOE 8872-40)
Master/slave operationUp to three units from the same series can be operated in parallel to increase the output power without limitations in the regulation rate or other parameters.
Optionally available parallel mounting sets take into consideration the appropriate safety standards and also provide simple data linking between the master and the slave units.
Standby/executeA convenient detail of the functionality is the output switch-off which allows immediate switching-off of the voltage and current values to 0 V or 0 A at standby. When activating the execute key, the set or programmed values for voltage and current are present without delay. Switching over can be carried out manually, using a remote control command from the PC, by means of an external TTL signal, or via an external switch contact.
Sensor linesAn innovative sensing circuit not only keeps the power supplied to your load extremely constant, it even protects sensitive loads if there is a break in a sensor line. The sensing inputs are available at the rear and can be activated/deactivated using a key
Arbitrary function
(Options)
TOE 9671 for TOE 8871-Serie
TOE 9672 for TOE 8872-Serie
Arbitrary functionThe power supplies of these series can be optionally equipped with an arbitrary function (curve memory integrated in the unit). The units execute an entered curve autonomously, even without a PC connection. A burst function defines the number of desired curve sweeps.
In addition, the curve memory can be divided into up to 3 blocks. Each individual block can be used repeatedly. The advantage is to be found in the extremely efficient use of memory space.
