About the power supply
1. Introduction
The laboratory power supplies of the series
PSI 8000 2U
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
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...5V or 0...10V.
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.
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 gal-
vanically isolated analog interface IF-A1 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.
Most models from 1000W feature an adjustable power regula-
tion circuit (with two exceptions, see technical specs), as well
as a „System Bus“ terminal which enables series connection as
master-slave or parallel connection with share bus.
The main functions at a glance:
•
Set voltage and current, each with 0...100%
•
Adjustable overvoltage threshold 0...110% UNom
•

Analog, Ethernet/LAN, Profibus)
•
Analog interface for external control and monitoring with 0...5V
or 0...10V (selectable) for 0...100%
•
Powers of 640W, 1000W, 1500W and 3000W
•
Temperature controlled fan
•
Status indication (OT, OV, CC, CV) in the display
•
