ENTERPRISE BRIEF INTRODUCTION

Commidity: Single Phase Anti-backcurrent Smart Power Meter

Model NO: DDSD9866-CA-NL

Application Scenarios: Used in photovoltaic power generation system to actively prevent or control the situation of reverse current when the power generation power is greater than the actual load.

Product Overview: 

The meter adopts guide rail installation, is especially suitable for Application with narrow installation space,and detects current, voltage, 

Power, electric energy and other parameters in the loop.support RS485 communication, Modbus RTU protocol. In a single-inverter system,

the meter is connected directly to the inverter,and if your drive has a built-in income rating table (RGM: this drive is called an income class

inverter), you can connect an external meter on the same bus as the RGM

Key Feature:   

  • Full power measurement & metering
  • DIN35 Rail Installation
  • High accuracy level
  • RS485 communication /ModBus RTU
  • Transformer input
  • Matching with inverter
  •  All or More Functions Customizable
