Now available from Powerline is the Power Patch family of open-frame DC/DC converter modules, a lightweight, low-profile 'topless' design for improved mechanical and thermal performance
The eP300-433 has four isolated outputs: 5 V/40 A, 3.3 V/40 A, 12 V/3 A and -12 V/1.5 A, and is ideal for space-critical applications in broadcasting, data communications, telecommunications and computer peripheral systems.
It operates over a universal input range of 90-250 V AC, and incorporates input power-factor correction and EMI line-filtering circuitry.
The high power density and the efficiency of 85% result from the use of novel circuit design techniques, including the use of MOSFET based synchronous rectification to give low forward voltage drop and minimal losses.
Other key features include the use of surface-mount components including low-profile transformers, plus a thermal design which eliminates the need for separate heatsinks.
