19D-37D Three Din-rail 30 Amp Kwh 3 Phase Smart Prepaid Electric Energy Meter Sub-meter
Description
19D series meter is designed for DIN-RAIL mounting, suitable for residential energy metering and smart energy project. The Modbus-RTU and pulse output communication allow seamless integration with data acquisition systems. Various sub-models are available, and prepaid (IC card) is optional. 19D series can transmit data by wireless (4G/5G, Rolar etc.). Moreover, extension modules are available in built-in and external these two versions.
The 19D-37D three-phase rail energy meter is an intelligent device for medium and low voltage systems (6-35KV and 0.4KV). It integrates data acquisition and control functions, adopts segment code LCD screen, and has functions including three-phase AC power measurement and calculation, Electricity accumulation, RS485 communication. In addition, the device can also be equipped with functions such as multi-rate energy metering, maximum demand metering, and 1 channel relay alarm output. The device also provides a communication interface to connect with the computer monitoring system, and supports the RS485 interface MODBUS-RTU or DL/T645-2007 communication protocol.
