WANTED

WTB: 48 VDC Power Supply - High Current

I am looking for a used 48 - 50 VDC, power supply that will supply 100 - 500 amps. These power supplies are generally known as Front End Power Supplies and consist of a 19" or 23" frame, with plug in 48 VDC power supply modules that operate in parallel. These types of supplies were in service at cellular sites or fiber optic huts, supplying high current 48 VDC to the equipment at the site. Ask your ham friends that work in the cellular or fiber industries if they may know of any that have been removed from commercial service. Several manufacturers made these supplies including Tyco, Lineage & HQ. Here are a couple of data sheets on the type of power supplies I am looking for: http://www.nelt.info/Doc/pdf/Np1500%20Datashheet%20V7.pdf http://www.ysjcpower.com/products/picture/np2500.pd
