- 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.
Digital and analog control interfaces
Digital: RS 232 / GPIB / USB / LAN
RS 232 and GPIB/USB/LAN (optional) interfaces with the following
scope of functions are available for communication between PC and
power supply:
- Adjustment of output values: voltage, current
and power
- OVP and limit adjustment, autocal function,
display, store and recall settings
- Switching on/off of output voltage
- Reading of actual values as well as
warning/fault states
The command syntax complies with the IEEE
488.2 standard. Standardized SCPI commands are processed.
Fast analog control
The power supplies can be controlled in
analog mode; i.e. the output
voltage and current can be adjusted independent of one another using
externally applied control voltages.
Short adjustment times for the output voltage are implemented using
balanced circuitry.
It is therefore possible to generate powerful and fast output
signals
without problem; up to approx. 700 Hz at 2 Vpp.
Interlock
By interrupting the interlock circuit, e.g. by an external emergency
stop switch, the power supply output becomes deenergized directly.
Output ON/OFF
A convenient feature is the output switchoff function which at
standby
permits immediate reduction of the voltage and current values to 0 V
and
0 A. When the output key is activated, the set or programmed values
for
voltage and current are present immediately. The switchover can be
carried out manually, via a remote control command from the PC, via
an
external TTL signal1) or via an external switching contact1).
- Interlock or inhibit option
required
Autocal-funktion The power supplies
are equipped with a self-calibration function protected by a
”security code”. This function can be manually executed from a menu
or also remote-controlled.
Price and performance
The exceptional specifications, extraordinary features, and best
possible processing quality provide the power supplies of the TOE 8950
series with an excellent price/performance ratio.is.
