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 12V output module, it
delivers 50W (4.2A) output with 36 to 75V input and
delivers 40W (3.5A) output while the input is 18 to 36V to
the same module. Typical efficiency of the 12V/4.2A
module is greater than 88%. 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.
