ELES6XM50A1000VM and S9XM300A1000VM are ideal instruments for small and medium-sized wind turbines or small hydropower plants. The RMS measurement system of these TELE devices is the best choice for this application, as it can generate alternating current with a frequency range from a few hertz to 400Hz.

These power meters transmit measurements of power, current, voltage, and energy in the isolated data stream of the ModBus RTU interface. In addition, broadband auxiliary power supplies ranging from 9VDC to 30VDC make them easy to use in harsh environments. By measuring the frequency of the AC voltage or current generated through digital means, the generator speed can be directly obtained from the energy meter. The integrated RS485 interface allows S6XM50A1000VM to connect to any ModBus host, such as PC HMI、 PLC、 WLAN、 Modems and Wi Fi access routers. The S6XM50A1000VM is one of the smallest single-phase energy meters on the market, and Vickers' current sensor can be easily installed in almost any distribution system.
