About the power supply
1.
Introduction
The laboratory power supplies of the series PSI 8000 T are very
compact and rugged devices and incorporate interesting features
within small dimensions. Apart from standard functions of power
supplies the user can define and recall different presets of set
values, supervise set values and actual values by definable limits
or create function runs of configurable preset values with the
integrated function manager.
The devices also feature an integrated analog interface that
can handle the common voltage ranges of 0...5 V or 0...10 V.
This offers a way of easily monitoring the device as well as total
remote control. The logical levels of the digital inputs and the
output can be modified. Output power adjustment is integrated
in models from 1 kW.
The 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 galvanically
isolated analog interface which can even better serve to control
the device by external means, like a PLC, as the internal interface.
The integration into existent systems is done very comfortably by
using an interface card, while there is no need to configure the
card at all or with only a few settings.
Via the analog interface, the power supply can als be operated in
connection to other power supply units, controlling these via the
interface. Or they can be controlled and monitored by an external
control system, like a PLC.
The device is microprocessor-controlled and thus delivers fast
and accurate measurement and indication of actual values.
The tower design allows space-saving conception of even com-
plex and highly productive applications, like for example industrial
test equipment with variable power for various demonstration and
testing purposes in research & development or educational areas.
The main functions at a glance:
• Set voltage and current, each with 0...100%
• Set power 0...100% (only with models from 1 kW)
• Pluggable interface cards (CAN, USB, RS232, IEEE/GPIB,
Ethernet/LAN, isolated analog, Profibus)
• Integrated, analog interface for external control and monitoring
with 0...5 V or 0...10 V (selectable) for 0...100%
• Powers of 320 W, 640 W, 1000 W and 1500 W
• Temperature controlled fan
• Status indication (OT, OV, CC, CV) in the display
• Standby mode
• 4 selectable memory sets, supervision function
• Function manager
• Adjustable internal resistance (optional)
