PL508 Power Supply System

The PL 508 is a high sophisticated, high density, programmable 8-channel floating low-voltage power supply system. Using the remote monitoring and control features it can be used to supply a large numbers of external load-channels with high power consumption also over long distances. Dynamic behavior adjustable by internal jumper (long-short sensed distances to loads).  Voltages, currents, temperatures and output power are programmed and controlled by the internal processor and illegal modes as well as failure will be detected.
