PRODUCT OVERVIEW
The MEV series is the new high performance
version of our 1W NMV series. The MEV series
is more efficient and offers improved regulation
performance from 1.8% for applications where a
wide output voltage variation can not be tolerated.
They are ideally suited for providing local supplies
on control system boards with the added benefit
of 3kVDC galvanic isolation to reduce switching
noise. The MEV series is currently available in an
industry SIP 7 or DIP 14 package.
