This product family provides up to 50 watts of power th in the industry standard 1/16 brick form factor (1.30x0.90) and pinout. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. For the 3.3V output module, it delivers 50W (15A) output with 36 to 75V input and delivers 40W (12A) output while the input is 18 to 36V to the same module. Typical efficiency of APPLICATIONS the 3.3V/15A module is greater than 90.5%. All modules are protected Optical Transport from abnormal input/output voltage, current, and temperature Data Networking conditions. For lower power needs, but in a similar small form factor, Communications please check out Delta S48SP (36W or 10A) and S36SE (17W or 5A) Servers series standard DC/DC modules.
