DESCRIPTION
The GS4T48-5is a 4WDC-DC converterdesigned
to providea 5V/800mAisolated power source.
The modulefeaturesa wideinput voltagerange (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
providedwith a SELVinput.
