performance 3W DC/DC converters, offering 3W
of available output power in a previously rated
2W package capable of operation over the full
industrial temperature range of -40ºC to 85ºC3.
Available in an industry standard SIP package,
with a pin compatible power upgrade path from
the 1W NME/NKE and 2W NML series’, they are
ideally suited for providing local supplies on
control system boards with the added benefit of
1kVDC galvanic isolation.
