DSM228R Single Phase Electric energy meter with RS485 Communication, cyclometer display. The meter is used to measure 50Hz or 60Hz active energy consumption from single phase two wire AC electricity net.
The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique, the key components and part all adopts long life type. The meter has the features of good reliability, small volume, light weight, specious appearance, etc. The meter is widely used in office buildings, shopping malls, residences, airports and metro, etc. The meter has RS485 communication module, which is convenient to meter-reading.
FUNCTIONS AND FEATURES:
1. Front board three fixed installation, the cover is made of high definition transparent glass, the meter base is made of Aluminium or steel which is after double-through antirust processing, and the terminal is made of bakelite which is moisture-resistant, fire-retardant, high temperature molded overall.
2. Unidirectional cyclometer 5+1 digits display (99999.1kWh), may select diamagnetism cyclometer. Or may select LCD display.
3. Standard configuration one port of pulse output passive (polarity), may select increase a distant port of pulse output passive (nonpolarity), and contact with all kind of AMR system conveniently.
4. There is a port of RS485 data communication. Standard configuration communication agreement complying with standard DL/T645-1997, can also choose any other communication agreement.
5. Three LED instructions power supply state, signal of energy impulse and communication state.
6. Single direction measures single phase two wire active power
7. Onsumption. It is nothing with direction of the flow of load current, complying with standard IEC62053-21, IEC62052-11.
8. Directly connect operation or through CT or PT & CT.
9. Adopts high reliable and long-life electric components, hioverload, do not need to calibrate for long-term operation
10. Direct connect operation, there are two types wiring you may select.
11. Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient to install. May select extended terminal cover, which is for protecting the safety of using electricity.
