SynchroBeeWith the goal to provide a very robust and highly valuable tool we designed one flexible and highly configurable power grid synchronization platform that allows multiple hardware and software configurations. It monitors, protects, connects and synchronizes (when one of the buses is maintained by a diesel generator) two three phase buses.

The data can then be sent through analog outputs or communication interfaces for further control, notification or visualization tasks. These can be RMS voltage, RMS current, Active power, Reactive power, frequency, etc.

The platform is originally equipped with the ZekaStream™ technology allowing high speed data logging within the microseconds range. This makes the device a highly valuable tool for catching transients and analyzing high-speed processes. Only one device with such a technology in your design is enough to change the way you commission the whole power plant.

Having numerous communication interfaces including Ethernet, RS485 and CANBus and utilizing Modbus, makes the integration with your industrial network an easy task. Profibus interface is also available using the GreenBee Industrial Gateway communication bridge.

Several digital and analog inputs and outputs are available for additional programming allowing extra flexibility during the system design or even when the project is in its final phase. The integrated Modbus master allows different Modbus slaves to be attached to extend IO and functionality.
