Single-output power supplies up to 200 W output power - TOE 8941

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.

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

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
