S1MMmA500VLM 3-phase power meter 500V universal input ModBus RTU/RS485 EF

S1MMmA500VLM – 3-phase power meter EF for industrial energy measurement

The S1MMmA500VLM from TELE Haase is the extended (EF) version of the 3-phase power meter up to 500V P-P with universal transducer inputs and Modbus RTU / RS485 interface. In addition to the complete standard measurement range, it offers additional functions such as THD, phase sequence, K-factor, maximum consumption recording, and power factor deviation analysis.
