PRO380-DC-MOD MID: Three-phase power meter, direct connection up to 100 A, MID Class B approval, RS485 Modbus, pulse output

The PRO380-MOD MID is a three-phase electricity meter designed for precise measurement of energy consumption in industrial and commercial installations. MID (Measuring Instruments Directive) certification attests to its accuracy and allows its use for official energy billing.

Measurement Type: Three-phase, suitable for 3 or 4-wire systems.
Certification: MID (according to EN50470-1 and EN50470-3, Class B), making it suitable for fiscal energy metering.
Communication: Equipped with an RS485 serial communication interface with Modbus RTU protocol, it allows integration with energy monitoring and management systems (BMS) or PLCs.
Pulse Output (S0): Features an S0 pulse output, proportional to the energy consumed, for easy connection to external data acquisition systems.
Display: Typically a backlit LCD display (e.g., 6+2 digit or 8 digit) for clear visualization of measured values directly on the device.
Mounting: Designed for easy DIN rail mounting.
Measurements: Capable of measuring various electrical quantities, including: Active energy (kWh) – often bidirectional (consumption and injection), Active power (kW). Possibly also reactive energy, apparent power, voltage (V), current (A), frequency (Hz) and power factor (cos φ), depending on the specific version. Possible applications: Energy accounting and billing in commercial, industrial, and residential buildings, Energy consumption monitoring for energy efficiency, Sub-metering in multi-user complexes, Integration into energy management and building automation systems, Monitoring of renewable energy production plants (e.g. photovoltaic).
