Description
Compact power supply for your applications
in the field of:
- Research / development
- Laboratory / testing / experiments
- Production / test bays
- Quality assurance
- Service / training
200 W in compact design - The TOE 8941
series single-output power supplies have an extreme compact design.
As a result of the high efficiency of all units, the complete output
power of 200 W is available at the front via safety sockets. A rear
output via a screw-type terminal block is optional.
Autoranging - Power supplies with autoranging can source
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 remote sensing circuit -
Benefit from an innovative sensing circuit which keeps the correct
voltage at the input terminals of the load. Additionally it 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 200 W can
then be reduced down to 5 % of the maximum output power.
Digital and analog control interfaces
Digital: GPIB / USB / LAN - GPIB, USB
and LAN interface with the following scope of functions are
available for communication between PC and power supply (option):
- Adjustment of output values: voltage, current
and power
- OVP and limit adjustment, autocal function,
display, store and
recall settings
- Switching on/off of output v
- Reading of actual values as well as
warning/fault statesde
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
8941 series with an excellent price/performance ratio.is.
