The DPM-4M electrical measurement unit, designed for DIN rail mounting, is intended for measuring the main electrical parameters in 4-wire three-phase networks (3L+N). It allows direct current measurement up to 63A and is designed and manufactured to accommodate all electricity consumption scenarios, adopting an advanced energy measurement method (IC), and utilizing advanced digital sampling and SMT technology.

It enables the measurement of the following electrical parameters: current per phase, voltage per phase and between phases, active, reactive, and apparent power per phase and total, power factor per phase and total, as well as the frequency of the network.

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-4M electrical measuring unit has an energy pulse output and an RS485 Modbus communication port.
