Inepro PRO380-Mod Three Phase 100A DC MID Energy Meter

Product Details

The PRO380 series is a range of 4 module, three phase energy meters consisting of 3 different types. They are available in a standard, M-bus or Modbus version. All meter types are equipped with an infrared interface and a selectable pulse output.

PRO380 energy meters display a number of instantaneous variables like voltage, current, active power, reactive power, apparent power, frequency and power factor on the LCD and via the different communication options. For calculating the total energy usage, there are 7 calculation modes available. All forward (import) and reverse (export) (re)active energy values are stored in different meter registers.

The PRO380 energy meters have an exceptional combination of a high accuracy class (1/B) for active energy measurement, a broad temperature range of -40°C to +70°C and an Imax of 100A.

All meters comply with the Measuring Instruments Directive 2014/32/EU. The MID approval ensures the accuracy and quality of the meter and enables its use in billing purposes.
