The electronic high performance power supplies of the PSI 9000 2U series are especially suitable for test systems 

and industrial controls due to their compact construction in a 19” enclosure with 2 height units (2U). Apart from 

basic functions of power supplies, set point curves can be produced in the integrated function generator (sine, 

rectangular, triangular and other curve types). Arbitrary curves can be saved to and loaded from a USB flash drive. 
For remote control using a PC or PLC the devices are provided as standard with a USB-B slot on the back side 

as well as a galvanically isolated analog interface. 
Via optional plug-in interface modules, other digital interfaces such as Profibus, ProfiNet, ModBus, CANopen and 

more can be added. These enable the devices to be connected to standard industrial buses simply by changing or 

adding a small module. The configuration, if necessary at all, is simple. Thus the power supplies may, for example, 

be operated with other power supplies or even other types of equipment or controlled by a PC or PLC, all using 

the digital interfaces.
In addition, the devices offer as standard the possibility for parallel connection in Share bus operation for constant 

current sharing plus a genuine master-slave connection with totalizing of the slave units is also provided as standard. 

Operating in this way allows up to 10 units to be combined to a single system with a total power of up to 30 kW.
All models are contolled by microprocessors. These enable an exact and fast measurement and display of actual 

values.

The block diagram illustrates the main components inside the device and their relationships.
There are digital, microprocessor controlled components (KE, DR, BE), which can be target of firmware updates.
