Description
The 19D-24D Three Din-rail Smart Dual Electricity Phase Price Wattmeter Energy Meter is an advanced solution for residential energy metering and smart energy projects. Designed for DIN-RAIL mounting, this intelligent device supports medium and low voltage systems (6-35KV and 0.4KV). With its seamless Modbus-RTU and pulse output communication, it can easily integrate with data acquisition systems. The meter features a segment code LCD screen and is equipped with functions such as single-phase AC power measurement, electricity accumulation, and RS485 communication. Optional prepaid (IC card) functionality is available, along with multiple sub-models for versatile applications.
This meter not only measures electricity consumption but also supports multi-rate energy metering and maximum demand metering. It is designed to be tamper-proof, ensuring reliability for revenue applications. The 19D-24D is compatible with both 50Hz and 60Hz systems, and it includes features such as a large LCD screen with backlight, built-in energy pulse output, and alarm output.
