DESCRIPTION
The MEE1 series is the new high performance version of our 1W NME series. The MEE1 series is more efficient and offers improved regulation performance 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 1kVDC galvanic isolation to reduce switching noise.
