PL508 Power supply System
The PL508 is a high sophisticated, high density, programmable 8-channel moderate 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 is adjustable via internal jumpers (long-medium-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.
The modular construction with a 19″ rack mountable power bin and a plug-in power supply box allows to swap the power supply without any tools and within shortest time.
