PRODUCT OVERVIEW
MEA1D0512DC 5 12 42 226 4.2 5.3 7 20 84 87 47 3394 121694
The MEA series is the new high performance
MEA1D0515DC 5 15 33 224 4.1 5.3 6 20 84 87.5 46 2641 105112
version of our 1W NMA series. The MEA series
MEA1D1205DC 12 5 100 97 3.6 4.5 9 20 81 84.5 43 3465 112889
is more efcient and offers improved regulation
MEA1D1209DC 12 9 56 95 2.6 3.5 7 20 83 86.5 64 3623 69665
performance 5% for applications where a wide
MEA1D1212DC 12 12 42 93 2.7 3.5 6 20 85 89 89 3267 69830
output voltage variation cannot be tolerated. They
MEA1D1215DC 12 15 33 94 2.3 3 6 20 84 88 76 2339 95016
are ideally suited for providing dual rail supplies
MEA1D1505DC 15 5 100 78 3.1 4 9 20 80 84 42 2929 59216
with the added benet of galvanic isolation to
MEA1D1509DC 15 9 56 76 2.2 3 6 20 82 87 50 2551 96783
reduce switching noise. All of the rated power
MEA1D1512DC 15 12 42 76 2 2.7 6 20 83 87.5 77 2665 102007
may be drawn from a single output providing the
