Description

The DPM-1P DIN rail-mounted electrical measuring units are designed and manufactured to accommodate all electricity consumption scenarios by adopting an advanced energy measurement method (IC) and utilizing advanced digital sampling processes and SMT technology. They are designed with a modular structure, have a compact size, and offer convenient installation and reliable operation.

The DPM-1P electrical measuring unit is designed for single-phase measurement in single-phase networks. It allows direct current measurement up to 40A and features a pulse output for energy measurement and an RS485 – Modbus communication port.
