Description

The DPM-2M electrical measuring unit, designed for DIN rail mounting, is intended for measuring the main electrical parameters in single-phase 2-wire (L+N) systems. It enables direct current measurement up to 63A and is designed and manufactured to accommodate all electricity consumption scenarios, adopting an advanced method of energy measurement (IC) and utilizing advanced digital sampling and SMT technology.

It allows measurement of the following electrical parameters: current, phase-neutral voltage, active, reactive, and apparent power, power factor, as well as network frequency.

It also measures active and reactive energies according to 4 tariffs and can be used for metering operations for electricity billing purposes as it is MID certified.

It is designed with a modular structure, has a compact size, and offers convenient installation and reliable operation.

The DPM-2M electrical measurement unit features an energy pulse output and an RS485 Modbus communication port.
