UPS software on SuSe 7.3

According to yast2 there are three software packets which could be used for the control of an Uninterrupted Power Supply (UPS) if I am right. Does somebody has knowledge of these three packets? Which of the three is easiest? I have an UPS of a local producer which is said to be based on Epsilon. I have not yet looked into Epsilon data. Further data on this local ICA product are more than scarce and today I finally was able to get an original cable for this UPS. It was nowhere to be found (for three years ;-)). I need detailed help in the setup.
