Description
The Bel x7AH-01H1A0 is part of the low cost non-isolated DC/DC converter series. The modules use a SMD or
vertical mount package for ease of layout and space savings. The output is widely trimmed from 1.2V to 3.3V.
Typical features include remote on/off, input under voltage lockout, over current protection and short circuit
protection.
