The AC to DC convertor has been designed to supply a regulated 12v DC supply.
 

The unit’s primary function is to work with door entry systems that only supply 12V AC to the magnetic lock. The unit is intended as a useful addition to supply 12v DC for uses such as key fob entry systems and door intercom systems.
 

Its small size makes it a very useful device not only for door entry systems but other applications where a small DC power supply with good regulation is required.
