DSM228R Single Phase Electronic Energy Meter with Communication Port

DSM228R	Single-phase Two-wire Electronic Active Energy Meter with RS485 Communication (Cyclometer Display)
DSM228CR	Single-phase Two-wire Electronic Active Energy Meter with RS485 Communication (LCD Display)

Functions and Features
1. Our electronic energy meter with communication port is installed by front board with three fastening pieces. The casing is made of high accuracy material.
2. 5 1 digits unidirectional cyclometer (99999.1kWh) is equipped. Diamagnetism cyclometer or LCD display (Configuration code DSM228CR) may also be selected.
3. The standard configuration uses one port of passive pulse output (polarity). A distant port of passive pulse output (non-polarity) can also be selected. This electronic energy meter with communication port conveniently contacts with all kind of AMR systems.
4. An RS485 data communication port is used. The standard configuration communication agreement complies with standard DL/T645-1997. Any other communication agreement can also be chosen.
5. The LED indicates power supply state, signal of energy impulse and communication state.
6. This electronic energy meter with communication port measures single phase two wire active power consumption. It has nothing to do with direction of flow of load current. It complies with standard IEC62053-21 and IEC62052-11.
7. With highly reliable and long- life electric components, our electronic energy meter with communication port doesn’t need to be calibrated for long- term operation.

Applications
The meter is used to measure 50Hz or 60Hz active energy consumption from single phase two wire AC electricity net.
It uses LSI (Large-scale Integration) and SMT manufacturing technique. All its key components and parts have long service life.
It is characterized by good reliability, small volume, light weight, attractive appearance, etc.
This electronic energy meter with communication port is used in office buildings, shopping centers, apartments, airports, metros, etc.
It is equipped with a RS485 communication module which is convenient for meter-reading.
