The DB02S/D series are miniature, DIP Package, isolated 2W DC/DC converters with 1,500VDC isolation. The DB02S/D series 
features fully regulated output and wide 2:1 input voltage ranges. The most convenient advantage is the modules with a low height of 
just 7.60 mm (0.30 inch) on the PCB. It offers short circuit protection and allows a wide operating temperature range of –40°C to 
+80°C. These isolated DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing 
― Delta Electronics, Inc. With creative design technology and optimization of component placement, these converters possess 
outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions
