High-performance power supplies - TOE 8871 (1000 W) to TOE 8872 (1500 W)

Overview

High performance and easy-to-use

An output power up to 1500 W is provided by the power supplies belonging to the TOE 8871 and TOE 8872 series; at the same time, output voltages can be generated up to 400 V and output currents up to 100 A depending on the model.

As a result of state-of-the-art switching controller technology and proven microprocessor control, these devices are suitable for completely universal application.

Together with a high effi-ciency, the power supplies are characterized by permanent load resistance, autoranging and a low weight.


PFC

A highly effective power factor corrector (PFC) ensures that the TOE 8871 and TOE 8872 power supplies react with respect to the mains source like a resistance without any capacitive, inductive or non-linear components whatsoever. The mains current input is therefore sinusoidal, in-phase with the line voltage, and thus free of reactive current components.

Easy-to-use
The devices are extremely easy-to-use, and the specifications are exceptional. Superb processing quality together with a large number of special functions mean that the power supplies of the TOE 8871 and TOE 8872 series can be counted among the very best currently available.

Integrated measurement
A further significant characteristic is the high-resolution measurement of the voltage, current and power values; these are output on 4-digit LED displays and can be read at a high rate in bus mode. This means that additional measuring instruments are usually superfluous.

Adjustment using incremental spinwheel
The output values are set using a wear-free incremental spinwheel with selectable sensitivity, thus guaranteeing reliable, exact setting of the output voltage, current and power even after many years of use.

Remote control: GPIB, RS 232 and analog
All devices can be remote-controlled as standard in analog mode, and optionally via GPIB and RS 232 interfaces with the standardized SCPI command set (SCPI: Standard Commands for Programmable Instruments). The system interfaces are characterized by a high setting rate and a high measuring rate. In addition to this, device driver software under “LabView“ is also available. Furthermore, all devices can be controlled at high precision via an electrically isolated analog controller (option).

Ethernet/LAN interface
For the TOE 8871 and TOE 8872 series power supplies a RS 232 Ethernet-Adapter is available to control the power supply remotely over LAN. The Ethernet-Adapter provides a TCP / UDP port to transmit SCPI commands to the power supply. An integrated web server allows easy access to the device to check the connection or to reconfigure the adapter. The ethernet adapter is preconfigured for the instrument and can be used in most networks without additional configuration.

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 quiet

The 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 current
With 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 rate

Die 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 operation
Up 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/execute
A 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 lines
An 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 on the front panel.

Arbitrary function

(Options)

TOE 9671 for TOE 8871-Serie

TOE 9672 for TOE 8872-Serie


Arbitrary function

The 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.
