2 Product overview
The automatic transfer switch concept is applied to any application requiring switching from the pri-
mary power line to secondary power line to ensure the supply of loads.
OMD200:
Analysing the voltage, frequency and the phase balance. Includes the generator START / STOP com-
mand.
OMD200 has two sensors to monitor two three-phase power lines, both able to work with single phase,
too. It has the capability to monitor two power supply lines and to manage a single change-over switch.
With DIP-switches it can be chosen whether or not the neutral line is connected. If OMD200 is used
without the neutral line, the external transformer must be used.
OMD300:
Analysing the voltage, frequency and the phase balance. Includes the generator START / STOP
command and the dual power supply (DPS) to motor operator.
OMD300 has two sensors to monitor two three-phase power lines, both able to work with single phase,
too. It has the capability to monitor two power supply lines and to manage a single change-over switch.
OMD300 has integrated voltage supply for the motor operator (Dual power source, DPS). The neutral
line has to be always connected.
