The document provides product descriptions for various components of the RPS (Remote Power Supply) system, including: 1) The central office (CO) unit which enables power transfer of up to 100W via twisted pair channels at a source voltage of ±190V. 2) Remote power (RP) units like the MRODx shelf that houses DC/DC converters and control units to provide up to 900W of output power. 3) DC/DC converter modules like the PDL that combine three converters to supply 45-75W per twisted pair at input voltages from 230-380V.

MRODx - AEU2232Dx - Power Supply Shelf
One PDL DC/DC converter module can be supplied over 3 twisted pairs. One AEU2232Dx MRODx shelf can take
four DC/DC PDL converters, os one MRODx shelf can be supplied over 12 twisted pairs. The received effective
power at the max. resistance of twisted pairs of 600R is min. 12 x 45W = 540W, and max. 12 x 75W = 900W at a
minimum resistance of twisted pairs.
