Construction and function
1.9.1
General description
The DC laboratory power supplies of the PSI 9000 DT series are especially suitable for the use in test and devel-
opment applications, in laboratories, research and industry. The robust enclosure with its carrying handle, which
also serves as tilt stand, adapts in shape and look to measuring devices of established manufacturers.
Apart from basic functions of power supplies, set point curves can be generated in the integrated function generator
(sine, rectangular, triangular and other curve types). Arbitrary curves, consisting of up to 99 points, can be stored
on or loaded from an USB stick.
For remote control using a PC or PLC the devices are provided as standard with an USB port and Ethernet (LAN)
port on the rear side, as well as a galvanically isolated analog interface. The configuration of the interfaces, if
necessary at all, is simple. All models are controlled by microprocessors.
