2. Product overview
The automatic transfer switch concept is applied to any application requiring switching from the
primary power line to secondary power line to ensure the supply of loads.
OMD100 is the basic version of the control unit of automatic switching equipment. It has two
sensors to monitor two three-phase power lines, both able to work with single phase, too. OMD100
can measure voltage, frequency and the phase balance of the primary and secondary power line.
OMD100 is able to command a single motorized change-over switch. The neutral has to be always
connected.
