Description of the basic devices
The basic units SITOP PSU8600 are primary-clocked power supplies for connection to 3-
phase AC line supplies. An electronically controlled DC voltage that can be set via a
potentiometer is available at the output of the devices. The device output is isolated, no-load
and short-circuit proof and has an electronic overload trip - or alternatively overload current
limiting (constant current), which can be set using an additional potentiometer. The device
output is switched-on and switched-off using a button.
LEDs signal the operating state of the device as well as that of the output. The electronic
overload shutdown is reset using the reset input and the button of the output. Additional
device functions are activated using DIP switches.
The device output is controlled and operating and diagnostics data transferred and externally
visualized or processed via the two integrated industrial Ethernet/PROFINET ports. An
integrated web server allows authorized users to read and write data remotely via a web
browser. Further, an OPC UA server is integrated in the devices (Open Platform
Communications Unified Architecture). This facilitates non-proprietary communication in
automation systems.
Add-on modules expand the functions of the basic units:
●
Expansion modules are used to increase the number of outputs.
●
Buffer modules buffer brief power failures for up to several seconds.
●
A UPS module and connected battery module buffer extended power failures up into the
hours range.
A basic unit can be expanded
●
With a maximum of 4 expansion modules (to provide a maximum of 33 outputs, including
the basic unit)
●
With a maximum of 2 buffer components (2 buffer modules, 1 buffer module and 1 UPS
module – or 2 UPS modules)
●
With a maximum of 6 supplementary modules in the system.
