DESCRIPTION
The GS4T48-5 is a 4W DC-DC converter designed
to provide a 5V/800mA isolated power source.
The module features a wide input voltage range (38
to 60V), low reflected input current and continuous
short-circuit protection. It is certified by UL, CSA
(level 3) and TUV as having SELV output when
provided with a SELV input.
