PSI 9000 15U/24U Series
1.9
Construction and function
1.9.1
General description
The electronic high performance power supplies of the PSI 9000 15U and PSI 9000 24U series have been de
-
signed for industrial high current and high power demands. Configured as mobile 19” cabinets in either 15 or 24
units of height they allow for operation in many different situations, such as electro-plating or high capacity battery
test and charging.
Both series are based on the 15 kW models of series PSI 9000 3U and thus offer the same set of functions and
control options.
For remote control using a PC or PLC the devices are provided as standard with an USB-B slot on the rear side,
as well as a galvanically isolated analog interface.
Via optional plug-in modules, other digital interfaces such as Ethernet, RS232, Profibus, ProfiNet, ModBus TCP,
CANopen, CAN 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 quick and easy. 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.
All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual
values.

Block diagram
The block diagram illustrates the main components inside the device and their relationships.
There are digital, microprocessor controlled components (KE, DR, HMI) inside which can be target of firmware
updates. The units are separate power modules, each with their own AC input and DC output. There is a master
unit and up to 5 slave units which don’t feature a control panel (HMI).
