1.9 Construction and function
1.9.1 General description
The electronic DC laboratory power supplies of the PSI 5000 A series are especially suitable for laboratories,
workshops, school and other educational facilities due to their compact construction in a desktop enclosure.
For remote control using a PC or PLC the devices are provided as standard with a 3-way interface on the rear
side. It includes a USB port, an Ethernet port and an analog connector. All connectors are galvanically isolated
from the DC output. The digital interfaces are equal regarding available control functions. The three interfaces can
even be operated simultaneously, while only one can be in control and the others can be used for read access.
Series or parallel connection are possible. The DC output clamps on the front are suitable to connect soldered
cable ends, spade lugs, cable end sleeves or 4mm Büschel plugs.
