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.
