Staff -- Test & Measurement World, 9/1/2004 2:00:00 AM
Rack-mounted in a 19-in. shelf, the TPCMQ24 DC/DC bus converter module converts 24 VDC to either 48 VDC or 54.4 VDC for use in telecom applications. Output current is 20.8 A at 48 V or 18.4 A at 54.4 V, producing a total power output of 1000 W. You can mount up to three of these 1U hot-swap modules in a single shelf to achieve 3000 W of total power. Modules operate over an input range of 20 VDC to 30 VDC (24 V nominal) with an efficiency of 89% and a power density of 12.5 W per cubic inch. Converters cost as low as $465 each, and the three-unit shelf costs $387, both in medium volumes. Unipower Telecom, Coral Springs, FL.www.unipowertelecom.com.
