APPLICATIONS
The MA-XD-3W&MB-XD-3W series offer 3
watts of output power from a package in an IC
compatible 24 pin DIP configuration without
derating to 71℃ ambient temperature.MA-XD-3W
&MB-XD-3W series have input voltage of
4.5-5.5,10.8-13.2,21.6-26.4&43.2-52.5VDC.
MA-XD-3W&MB-XD-3W features 1000VDC of
isolation voltage. A safety designed meet to
EN60950-1 and UL60950-1. All models are
particularly suited to telecommunications,
industrial, mobile telecom and test equipment
applications.
