The isolating transformers are used for appliances, where the standards permit low voltage use (i.e. 220V) for services and supplies of actuators, small motors or to isolate parts of installations from the current mains.
The MMI/500 family is built with two identical outputs, each with half power, which can reach, after making a series or parallel connections, respectively the voltages 220 or full power 110.
If you connect the secondaries in parallel, please take special care in connecting the terminals of 0V with 0V and 110V with 110V, to avoid short-circuiting
