PSI 10000 4U Serie
1.9
Construction and function
1.9.1
General description
The electronic high performance power supplies of the PSI 10000 4U series are especially suitable for industrial
test which have a demand for high power. All models in this series have a rated power of 30 kW and offer high
currents or high voltages to cover a broad spectrum of applications.
Apart from basic functions of power supplies, set point curves can be generated in the integrated function gener
-
ator (sine, rectangular, triangular and other curve types). Arbitrary generator curves can be saved to and loaded
from an USB stick.
For remote control the devices are provided as standard with USB and Ethernet ports on the rear side, as well as
a galvanically isolated analog interface. Via optional plug-in interface modules, other digital interfaces such as for
RS232, Profibus, ProfiNet, ModBus TCP, CAN, CANopen or EtherCAT 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.
In addition, the devices offer as standard the possibility for parallel connection in so-called Share bus operation
for constant current sharing, plus a true master-slave connection with totaling of all actual values is also provided
as standard. Operating in this way allows for up to 64 units to be combined to a single system with a total power
of up to 1920 kW.
Alternatively to the standard air-cooled version there are also water-cooled available which are usually configured
and offered in cabinet systems with a complete water cooling distribution inside. For DIY water-cooled systems
single units can also be obtained upon request.
