Product Introduction

Features & Benefits

High-precision Power Quality and Electricity Parameter Measurement

  • High-precision Class 0.5S bidirectional energy and electricity parameter measurement, complies with IEC 62053 criteria
  • Supports power quality measurement of total / individual harmonic distortion and current / voltage unbalance

Options for front panel

  • DPM-C520/C320 have the same function but can be applied in different space conditions

Parameter Grouping Function

  • All electricity data can be combined as a parameter group that allows access for master controllers (including PLCs, SCADA and EMS). This function reduces reading time as well as enhances real-time data accessibility of the master controllers
  • Combines several discontinuous register addresses to one continuous address, reducing commands to achieve high-efficiency data acquisition of the master controllers (SCADA and PLC)

Simple Installation and Operation

  • The DPM-C520 adopts fixing clips on both sides of the meter for easy installation without requiring tools and screws
  • Supports the MODBUS protocol. All parameters can be transmitted to the master controllers via the built-in RS-485 communication interface



  • The DPM-C520 is suitable for: energy management, medium or low voltage distribution systems, smart switch cabinets, energy management systems, factory automation systems, building automation systems, railway energy management systems, electric heating systems, wind power systems, energy storage systems, electric grid measurement, and energy quality analysis.
