Altronix Vertiline563V is a EIA 19" 1U rack mountable dual independent power supply with optional battery backup that provides 56VDC. It is intended primarily to be used in conjunction with respective Altronix current and future products that requires 56VDC input such as: eBridge4PCRX, eBridge16PCRX & eBridge1PCRX multi-port & single port IP/PoE over coax adapters. However, it can also be employed wherever 56VDC level power sources are needed. There are applications which may require delivering power in a range of 48VDC to 57VDC over CAT5 cable for distances up to 100m. For these applications, transmission at the higher voltage is more efficient, as it reduces cable losses when compared to the lower voltage.
