PRODUCT OVERVIEW
The MER1 series is the new high performance
version of our 1W NMR series. The MER1 series
is more efcient 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 benet
of 1kVDC galvanic isolation to reduce switching
noise.
