PRODUCT OVERVIEW
The MEV3 series is a new range of high
performance 3W DC/DC converters, offering 3W
of available output power in a previously rated
2W package capable of operation over the full
industrial temperature range of -40ºC to 85ºC.
Available in an industry standard SIP package,
with a pin compatible power upgrade path from
the 1W NMV/MEV and 2W NMK series’, they
are ideally suited for providing local supplies on
control system boards with the added benefit of
3kVDC galvanic isolation.
FEATURES
RoHS compliant
Typical effi ciency from 83%
Power density 1.9W/cm3
Wide temperature performance at full
3 Watt load, –40°C to 85°C
UL 94V-0 package material
No heatsink required
Industry standard pinout
3kVDC isolation (1 minute)
5V & 12V input
5V, 9V, 12V, & 15V output
Fully encapsulated with toroidal
magnetics
No external components required
No electrolytic or tantalum capacitors
UL 60950 recognition pending
