PL512 Power Supply System
The PL 512 is a high sophisticated, high density, programmable 12-channel floating low-voltage power supply system. Using the remote monitoring and control features either via USB or Ethernet it can be used to supply external load-channels with high power consumption also over long distances. Up to 3kW (3Ubox) DC output power can be provided.
Voltages, currents, temperatures and output power are programmable and controlled by the internal processor. Illegal modes as well as failure conditions will be detected. Dynamic behavior is programmable via USB port (long-moderate-short sensed distances to loads).
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.
