Brick, 18~75V wide input, single
output, isolated DC/DC converter, is the latest offering from a world
leader in power systems technology and manufacturing ― Delta
Electronics, Inc. This product family provides up to 50 watts of power
in the industry standard 1/16
th
brick form factor (1.30”x0.90”) 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
the 3.3V/15A module is greater than 90.5%. All modules are protected
from abnormal input/output voltage, current, and temperature
conditions. For lower power needs, but in a similar small form factor,
please check out Delta S48SP (36W or 10A) and S36SE (17W or 5A)
series standard DC/DC modules.
