1. Introduction
The laboratory power supplies of the series PS 8000T are very
compact and rugged devices and incorporate interesting features
within small dimensions.
Apart from standard functions of power supplies the user can de-
ne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, RS232, USB or GPIB/IEEE provide an even wider
spectrum of control and monitoring functions by means of a PC.
The integration into existent systems is done very comfotably by
usinganinterfacecard,whilethereisnoneedtocongurethecard
at all or with only a few settings.
Via the analogue 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 conceptioning of even
complex and highly productive applications, like for example indu-
strial 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%
» Adjustable overvoltage threshold 0...110% Unom
» Pluggable interface cards (CAN, USB, RS232, IEEE/GPIB)
» Analogue interface for external control and monitoring with
0...5V or 0...10V (selectable) for 0...100%
» Powers of 320W, 640W, 1000W and 1500W
» Temperature controlled fan
» Status indication (OT, OVP, CC, CV) with LEDs
» Standby mode
» 5 selectable memory sets
