The MEE1 series is the new high performance
MEE1S0312DC 3.3 12 83 8.7 11 14 40 352 81 84 48 4040
version of our 1W NME series. The MEE1 series
MEE1S0315DC 3.3 15 67 7.8 10 12 35 350 82 84.5 50 3792
is more efficient and offers improved regulation
MEE1S0503DC 5 3.3 303 8 10 22 45 246 76 80 39 3213
performance for applications where a wide output
MEE1S0505DC 5 5 200 5.6 7 19 40 237 80 83 46 3990
voltage variation can not be tolerated. They are
MEE1S0509DC 5 9 111 6.8 9 13 35 238 80 83.5 53 4526
ideally suited for providing local supplies on
MEE1S0512DC 5 12 83 6.5 8 11 35 233 81 85 49 3756
control system boards with the added benefit
MEE1S0515DC 5 15 67 5.7 8 9 30 230 83 85.5 46 3240
of 1kVDC galvanic isolation to reduce switching
