DESCRIPTION
The GS5T48-12 is a 5W DC-DC converter designed to provide a 12V/420mA isolated power
source.
Themodulefeaturesawide input voltagerange(38
to 60V), low reflected inputcurrent andcontinuous
short-circuit protection. It is certified by UL, CSA
(level 3) and TUV as having SELV output when
providedwith a SELVinput.
