Compact power supply for your applications

The TOE 8941 series power supplies are suitable for applications associated with:
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).

1)
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.
