Single-output and dual-output power supplies
up to 400 W output power - TOE 8951 to TOE 8952

Overview

Performance in absolute perfection

Convenient performance for your applications

The power supplies from the TOE 8950 range are suitable for applications associated with:
Research / development
Laboratory / testing / experiments
Production / test bays
Quality assurance
Service / training



400 W in compact design
The single-output and dual-output power supplies from the TOE 8950 range have an extremely compact design. As a result of the high efficiency of all units, the complete output power of 400 W is available without problem over wide voltage and current ranges at the front via safety sockets and at the rear via a screw-type terminal block.

Autoranging
Power supplies with autoranging can output their rated power over a wide and stepless range of voltage and current combinations.
Autoranging power supplies from TOELLNER have a significantly larger operating range than standard power supplies with the same output power.



Adjustment using incremental spinwheels
The output values are adjusted with a selectable resolution using wear-free incremental spinwheels, guaranteeing reliable and precise setting of all output parameters and operating functions even after many years of use.

Display
The set and measured values for voltage, current and power as well as the menu control functions are output on a 2-row LCD with 20 characters/row.

Highest degree of safety
is guaranteed for your applications by comprehensive protective measures: adjustable overvoltage protection, limit function, fast power OFF switching, polarity reversal protection, resistance to reverse current, various internal electronic monitoring functions.

Innovative sensing circuit
An innovative sensing circuit not only keeps the power supply to your load extremely constant, it even protects sensitive loads if there is a break in the sensor line. The sensing inputs are available at the rear.

Adjustable output power
The possibility for directly setting the power is a further exceptional feature of this series. The output power of 400 W with single-output power supplies or 2 x 200 W with dual-output power supplies can then be reduced down to 5 % of the maximum output power.

Tracking mode
With dual-output power supplies, automatic tracking permits control of the output voltage of part 2 as a function (0 – 100 %) of part 1 with retention of all control properties.

Arbitrary function

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. Dual-output power supplies of the TOE 8952 series have a separate curve memory per output. Two signals can then be output synchronous to one another. A burst function defines the number of desired curve sweeps.
In addition, the curve memory can be divided into up to 10 blocks. Each individual block can be used repeatedly. The advantage is to be found in the extremely efficient use of memory space.
The new and powerful software from TOELLNER permits fast and convenient input of curves using a graphic curve editor. Oscilloscope signals recorded in a vehicle can be read in directly and subsequently simulated. Voltage dips, starting processes in the vehicle, and noise voltages on the vehicle electrics can thus be simulated rapidly and without problem. Standardized test pulses in accordance with DIN 16750 or ISO 7637, such as load dump test pulses (also clipped), jump starts and reset response, or specific and standardized test curves from many different vehicle manufacturers, can be simulated and are included in the scope of delivery. New and future versions from manufacturers, as well as new test versions, are implemented can be entered in next to no time.

TOE 9151 or TOE 9152 option required (arbitrary function in the unit) if curves are to be output via internal memories.

Application example
Example of a sinusoidal signal with start block for initialization process, repetition block with a sinusoidal signal and 5 sweeps, and an end block for switching off a consumer.
