FEATURES Basic/supplementary isolation to
UL609502 ANSI/AAMI ES60601-1 Single and dual outputs UL 94V-0 package material SIP package style 5.2kVDC isolation ‘Hi Pot Test’ 3.3V, 5V, 12V, 15V & 24V inputs 3.3V, 5V, 9V, 12V & 15V output Internal SMD construction Fully encapsulated with toroidal magnetics Pin compatible with the MEV, NMV, NMK,
MEJ2, & NMJ series PRODUCT OVERVIEW 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.
