About the device
1. Introduction
The laboratory power supplies of the series PS 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 5 different presets of set values or make use of
the integrated analogue 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 optionally available, digital interface cards for either CAN,
RS22, USB or GPIB/IEEE provide an even wider spectrum of
control and monitoring functions by means of a PC. Models from
1000W feature an adjustable power regulation circuit, as well
as a „System Bus“ terminal which enables series connection as
master-slave or parallel connection with share bus.
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 analogue interface, a 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 devices are microprocessor-controlled and thus delivers fast
and accurate measurement and indication of actual values.
