Power System Controller
Description
The PSC 1 is a simple power system controller for small power systems.
It consists of a compact central unit providing basic I/O periphery, and of
an analogue based communication bus to the rectifiers. The user friendly
display quickly displays basic information about the current status of
the power system. The controller’s battery management with regularly
accomplished capacity tests is one of the key factors for the availability of a
power system. The PSC 1 controller allows also remote alarming by means
of potential-free relay contacts.

Description
The PSC 3 is a 3rd generation power system controller for small to very lar-
ge and complex power systems. It consists of a central unit, which provides
basic I/O periphery, and of a very reliable CAN standard based communi-
cation bus. The front end modules are located close to the elements to be
monitored. The benefit is an easy wiring, which is perfect for expandable
power systems with decentralized distributions (BDFB) and batteries in
separate rooms. The integrated PLC offers the flexibility for monitoring and
control of auxiliary devices, later functions upgrade and system capacity
expansions. The PSC 3 allows remote alarming by means of potential-free
relay contacts or via modem or LAN / Ethernet. The SNMP offers enhanced
remote alarming and is designed to work with SNMP managers. An integra-
ted web server offers a user friendly interface for detailed monitoring and
control with a standard web browser.
