Description
The Bel x7AH-01Hxx0 series are part of the low cost non-isolated DC/DC converter series. These modules use
a SMD or vertical mount package for ease of layout and space savings. The output is closely regulated and the
efficiency of 5V output is typically 90% at full load. Typical features include remote on/off, input under voltage
lockout, over current protection and short circuit protection.
