About the device
1. Introduction
The high efciency power supplies of the series PSI 8000 3U
are ideally suited for test systems and industrial control facilities
by their 19“ draw-out case.
Apart from standard functions of power supplies the user can
dene and recall different presets of set values, supervise set
values and actual values by denable limits or create function
runs of congurable preset values with the integrated function
manager.
Optionally available, digital interface cards provide an even
wider spectrum of control and monitoring functions by means
of a PC. Another optionally available extension card is the gal-
vanically isolated analogue interface IF-A1 which can serve to
control the device by external means, like a PLC.
The integration into existent systems is done very comfortably
by using an interface card, while there is no need to congure
the card at all or with only a few settings.
All models feature an adjustable power regulation circuit, as well
as a „Share Bus“ terminal which enables parallel connection
with symmetric current distribution.
The main functions at a glance:
• Set voltage, current and power, each with 0...100%
• Adjustable overvoltage threshold 0...110% U
Nom
• Optional, pluggable interface cards (CAN, USB, RS232, IEEE/
GPIB, Ethernet/LAN, Probus)
• Optional, analogue interface for external control and monito-
ring with extended features
• Power ratings of 3.3kW, 5kW, 6.6kW, 10kW or 15kW; in
cabinets extendable up to 150kW
• Temperature controlled fans
• Status indication (OT, OV, CC, CV) in the display
• 4 selectable memory sets, supervision function
• Function manager
• Adjustable internal resistance (optional)
• High speed ramping (optional)
• Parallel connection with Share bus
