DESCRIPTION
The GS4T48-5is a4WDC-DC converterdesigned
to providea5V/800mAisolatedpower source.
Themodulefeaturesa wideinputvoltagerange(38
to 60V), low reflected inputcurrentand continuous
short-circuit protection. It is certified by UL, CSA
(level 3) and TUV as having SELV output when
providedwith a SELVinput.
