The MEJ1 series are single and dual output DC/
DC converters in a 7 pin SIP package style offering
an isolation and insulation upgrade path from
the NMV & MEV1 series’. The MEJ1 series has
UL60950 and ANSI/AAMI ES60601-1 recognition,
which makes it ideal for applications where safety
and miniaturisation are of paramount importance.
