EMA-D9

EMA-D6

EMA-D6 Three-phase power meter for DIN rail mounting

Compact, versatile network analyzer for energy cost and basic network and asset management applications. Thanks to its large measured voltage range, the EMA-D6 with multi-range power supply can be connected in any low and medium voltage system up to a rated system voltage of 690 VAC. The RS-485 or Ethernet interface can be used for communication. In addition, the EMA-D6 has a multifunctional digital outputs using an alarm. The analyzer can accept up to 4 digital inputs.
