APPLICATION
DDS228, 1 phase 2 wire active electronic kilowatt-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 (Largescale
Integration) and SMT manufacturing 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 Aluminum or steel which is
after double-through anti rust processing, and the terminal is made of
bakelite which is moisture-resistant,fire-retardant,high temperature molded
verall.
-5+2 or 6+1digits LCD display.
-Standard configuration one port of pulse output passive (polarity),may
select increase a distant portof pulse output passive (non-polarity),
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,
overload, do not need to calibrate for long-term operation.
-Direct connect operation,there are two types wiring you may select.
