Description The Bel x7AH-03Exx0 Series are part of the low cost non-isolated DC/DC power converters. The modules use a surface mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82mm. The output is closely regulated and the efficiency of 5V output module is typically 95% at full load. Typical features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection. Part Selection Output Voltage Input Voltage Max. Output Current Max.
