The new series PSI 8000 3U extends the previous series PSI 8000 2U by 18 new models with power ratings of 3.3kW up to 15kW in 19" rack housings and 3U height, also configurable into cabinet systems of up to 150kW and up to 42U upon customer requirements.

Output voltages between 40V and 1500V, output currents between 30A and 5100A and output powers between 3.3kW and 150kW are available. The output terminal is located in the rear panel. All models are equipped with a flexible auto-ranging 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 already be covered by one unit. The 40V models are made to meet the requirements of the low-voltage directive.

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 varying 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, output power or the optional internal resistance is realised by two rotary knobs. These knobs are also used to set various parameters in the device setup menus as well. To prevent unintentional operations, all controls like pushbuttons or knobs can be locked.

For remote control the device by default features an internal analogue interface, which is not galvanically isolated. Alternatively, it can be monitored and controlled by various digital and retrofittable interfaces.

Options:

• Retrofittable digital interfaces (USB, RS232, CAN, GPIB, LAN/Ethernet, Profibus)
• Analogue, galvanically isolated interface
• Internal resistance control
• High-Speed (increased dynamics by decreased output capacity)
• Water cooling
• Cabinet systems, each with up to 60kW (12U), 90kW (29U) or 150kW(42U)
