PRODUCT OVERVIEW
The MEA series is the new high performance version of our 1W NMA series. The MEA series is more efficient and offers improved regulation performance ≤5% for applications where a wide output voltage variation cannot be tolerated. They are ideally suited for providing dual rail supplies with the added benefit of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single output providing the total load does not exceed 1 Watt.
