Dual-output and dual-output power supplies up to 320 W
TOE 8851 to TOE 8852, In-phase regulation

Overview

A proven concept
has been used for the new, systemcompatible single-output and dual-output power supplies of the TOE 8840 and TOE 8850 series.

Exceptional specifications are achieved with a total output power of 160 W or 320 W as a result of the classical in-phase control principle.

A total of 22 different models deliver voltages up to 130 V and currents up to 20 A. With a resolution of 12 bits in the voltage and current ranges, a simple and convenient user interface, and the excellent specifications, these instruments are suitable for both manual and busbased modes.

Integrated measurements
A further significant characteristic is the high-resolution measurement of the voltage and current 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 spinwheels
The output values are adjusted with a selectable sensitivity using wear-free incremental spinwheels, thus permitting reliable and precise adjustment of the output voltage and current even after many years of service.

Remote control (option)
All instruments can be remote-controlled in analog mode as well as via GPIB and RS 232 interfaces using the SCPI command set (SCPI: Standard Commands for Programmable Instruments). The system interfaces are characterized by a high response and measuring rate. In addition, instrument driver software is available under “LabView“.

Automatic calibration
Fast and convenient calibration of all output parameters is possible externally within a few minutes without any adjustment of trimmers or interventions in the instrument. This “software calibration“ can be carried out simply using the control elements or supported by a computer within a test system. The “software calibration“ provides an advantage which should not be underestimated when considering the regular calibration intervals which are becoming increasingly important in quality assurance systems.

Voltage or current source
Depending on the values set for the voltage and current, each power supply can be operated as a voltage source or a current source depending on the load conditions. All outputs can be connected in parallel or series without problem.

High performance and exemplary operating characteristics

- In-phase regulation

Tracking function
The automatic tracking mode with dualoutput power supplies means that it is possible to control the output voltage of output 2 as a function (0 % to 100 %) of output 1 with retention of all control properties.

Remote control
Command syntax in accordance with IEEE 488.2 with command set switchable between compatible TOELLNER commands and SCPI commands.

GPIB interface (option)
Interface connection in accordance with IEEE 488.1; electrically isolated from main outputs. The device address can be set as desired per menu.
Setting rate: approx. 25 settings/s
Measuring rate: approx. 20 measurements/s

RS 232 interface (option)
9-pin D-SUB connector; electrically isolated from the main outputs. Transfer: half-duplex mode, asynchronous; 110 to 19200 baud adjustable permenu.
Setting rate: approx. 20 settings/s
Measuring rate: approx. 15 measurements/s

Additional functions
These modern, proven and exceptionally well equipped power supplies are additionally characterized by supplementary functions such as the saving of 100 instrument settings, the standby circuit for the power outputs, sense and tracking modes.

Price and performance
In addition to the exceptional specifications and characteristics, all power supplies of the TOE 8840 and TOE 8850 series have a remarkable price/performance ratio.

Common operating functions
Anzeige Voltage und Current:
Display of voltage and current: separately on two 4-digit displays for all single instruments; on two selectable 4-digit V/A displays for the dual instruments. Constant voltage or constant current mode is indicated by single LEDs.
