Installation and operating instructions, OMD200 and OMD300 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. OMD200: Analysing the voltage, frequency and the phase balance. Includes the generator START / STOP command. 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...
