Description
8 Wire Pairs Downconverter
for the Remote Powering System RPS 1600
The PSR 0831 is a highly efficient, IP20-protected remote counterpart for the PSC 1600 / PSC 08xx converting the incoming voltage to 48 V DC for powering of active network components. The PSR 0831 delivers up to 120 W via eight feeding lines with a power efficiency of up to 92%. To convert the full power of one PSC 1600 (240 W) / PSC 08xx (120 W) at the remote site, two / one PSR 0831 are / is required. When cascading of up to 4 x PSR 0831 directly the output power is up to 480 W. The use of six PSC 1600 and cascading of twelve PSR 0831 (when using a power rail) delivers up to 1,440 W to the remote site. The PSR 0831 units can be mounted by using additional mounting brackets and mounting rails into a 19” or ETSI rack system.
