Product description
Note: Product discontinued. The product is replaced by a completely identical product PRO380-Mod direct smart energy meter. This is a full-fledged alternative, it differs only in the logo.The KLEFR 6934 0.25-100A Modbus MID energy meter has an RS485 communication interface and the Modbus RTU protocol. The KLEFR 6934 combines a high accuracy class of 1/B and a wide temperature range (-40 °C … + 70 °C).
The KLEFR 6934 can also use an infrared port (with a wavelength of 900–1 000 nm) for programming and communication with the device. Various communication modes then offer over 60 variables such as kWh, active and reactive energy, forward and reverse energy, power factor, etc.
The equipment includes a resettable daily counter - energy consumption can then be calculated in five different modes.
