The RSPS380 remote power supply system provides the optimum power supply solution for such last-mile access technologies as DSLAM dropping and downward moving of integrated access points.
 
With the application of the high-frequency switch power technology, the RSPS380 converts the -48V power of an equipment room into 190V power through the DC/DC conversion and transfers the power to a remote end at a maximum of 15 km away over composite optical fibers or copper wires. The remote end will rectify the received power into -48V and feed to the equipment after DC/DC conversion.

The RSPS380 features complete safety prevention measures, stable performance, ultra-long service life and a maximum output power of 540W.

The product has found wide application in power supply and backup power supply of low-capacity communication access points and TV access points.
