The extensive integrated monitoring functions for all output parameters with adjustable delays of alerts simplify test assembly, such that the usual external monitoring is mostly unnecessary. The easily readable graphic display shows a clear representation of set values, actual output values, the operational state and the current functions of the operation press buttons. For all necessary information and adjustments the user is guided by a clear menu.

For monitoring the correct output voltage and output current, lower and upper limits can be defined. If the deviation exceeds the adjusted limits, three possibilities are available as to how the appliance should react.
- Signals are displayed only; even the fault is still active, without affecting to the output.
- Warnings remain active and must be acknowledged after the fault is removed.
- Alarms will shut off the output instantly in case the deviation exceed the adjusted limits. Alarms and Warnings can be signalled audibly.

Set values and actual values of output voltage, output current and output power are clearly represented on the graphic display. The operating state of the device, the menu guidance and the current assignment of the pushbuttons are also shown on the display. So the user is able to operate the unit intuitively. The adjustment of output voltage, output current and output power, or optional internal resistance, is realised by two rotary knobs. These knobs are used to set parameters in the device setup menus as well. To prevent unintentional operations, all controls like pushbuttons or knobs can be locked.

Options:

• Digital interface cards (USB, RS232, CAN, GPIB, LAN/Ethernet, Profibus)
• Analogue, isolated interface card
• Internal resistance control

Output voltages between 16V and 360V, output currents between 4A and 60A and output powers between 320W and 1500W are available. The output terminal is located in the front panel. Units with more than 1kW output power are equipped with a flexible power output stage to provide a higher output voltage by reduced output current or a higher output current by reduced output voltage, always regulated by the maximum output power. So, a wide application-spectrum can be covered with an unit.

Set values and actual values of output voltage, output current and output power are clearly represented on the graphic display. The operating state of the device, the menu guidance and the current assignment of the pushbuttons are also shown on the display. So the user is able to operate the unit intuitively. The adjustment of output voltage, output current and output power, or optional internal resistance, is realised by two rotary knobs. These encoders are required for changing values in the different menus as well. To prevent unintentional operations, all operation controls may be locked.

The series PSI 8000 2U offers identical functionality, as well as different models, in a 19" draw-out case with 2U and output on the rear.

Options:

• Digital interface cards (USB, RS232, CAN, GPIB, LAN/Ethernet, Profibus)
• Analogue, isolated interface card
• High-Speed (increased dynamics by decreased output capacity, for models from 1kW)
• Internal resistance control
• Two-quadrants module (internal, active load with car ignition sequence according DIN 40839)(2U models only)
