Compatible 12V Adapter for Chamberlain

This 12V AC/DC adapter powers Chamberlain NLS1 and NLS2 intercom systems plus the Dakota Alert M538-BS MURS base station radio. It replaces the original CA0725 and CHNLS1 supplies with a new, non-OEM unit built to the same voltage specification.

Input range and cable length set the installation

The adapter accepts 100 to 240V at 50 to 60Hz, so it works on mains supplies worldwide without a separate transformer. A fixed 4FT cord reaches nearby wall outlets but cannot span longer distances without an extension lead.

12VDC output is the single specification that must

The connected device must require exactly 12VDC and a matching barrel tip; any other voltage or connector will not operate safely. Buyers who need a different output voltage or a longer lead cannot use this adapter.
