Dallas—Tyco Electronics' EUK240 series of DC/DC eighth-bricks delivers 240 watts for 9.6-volt intermediate bus applications. Its unregulated, 5:1 fixed ratio output is suited to enterprise, server and storage, datacom, and general networking applications.
The single-output converters, working from a 36 to 60 VDC input, provide up to 34 amps. Features include a load regulation of 500 mV, maximum output ripple and noise of 150 mV p-p, and typical efficiency of 96 percent. The device delivers full output at up to +55°C (no derating, 200 lfm cooling). Additional features include built-in filtering for both input and output, remote on/off logic, output trimming functionality, and over-temperature and output over-current/voltage protection. Optional features include auto restart after fault shutdown.
