APPLICATION
DSM228C single phase two wire active electronic watt-hour meter,LCD 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, light weight, specious appearance, etc..
The meter is widely used in office buildings, shopping malls, residences, airports and metro,etc.
| FUNCTIONS AND FEATURES |
| ?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. |
| ?5+2 or 6+1digits LCD display. |
| ?Standard configuration one port of pulse output passive (polarity),may select increase a distant port of pulse output passive |
| (nonpolarity),complying with standard IEC62053-21. |
| ?Single direction measures single phase two wire active power consumption. It is nothing with direction of the flow of load |
| current,complying with standard IEC62053-21,IEC62052-11. |
| ?Adopts high reliable and long-life electric components,hioverload, do not need to calibrate for long-term operation |
| ?Direct connect operation,there are two types wiring you may select. |
