PS 9000 3U Series
1.9 Construction and function
1.9.1 General description
The electronic high performance power supplies of the PS 9000 3U series are especially suitable for test systems
and industrial controls due to their compact construction in a 19” enclosure with 3 height units (3U).
For remote control using a PC or PLC the devices are provided as standard with an USB port and an Ethernet port
on the back side as well as an analog interface. All interfaces are galvanically isolated up to 1500 V DC.
In addition, the devices oer as standard the possibility for parallel connection in Share bus operation for constant
current sharing. Operating in this way allows up to 16 units to be combined to a single system with a total power
of up to 240 kW.
All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual
values.
