DTS866 Three-phase four wire Electronic Watt-hour Meter (cyclometer display-DSM866-02)
APPLICATION
DSM866-02 three phase four wire electronic active energy meter, cyclometer display.
The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.
The meter, which adopts LSI (Large-scale Integration) and SMTmanufacturing technique, is widely used in office buildings,shopping malls,residences,airports and metro,etc.
FUNCTIONS AND FEATURES
♦Meter base is ABS fire-retardant plastic(may select PC),meter cover & terinal cover is transparent PC or AS or non-transparent ABS. Meter terminal block is made of bakelite which is moisture-resistant,fire-retardant,high temperature molded.
♦Unidirectional cyclometer 5+1 digits display total,may select 6+1 digits display,may select diamagnetism cyclometer.Or may select LCD dislay.
♦Adopts ATT7030A chip,the key components and part all adopts long life type .
♦Adopts the newest electric integrated circuit which contains digital multiplier,greatly improved dynamic working range of the meter.
♦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 three phase four wire active power consumption.It is nothing with direction of the flow of load
current,complying with standard IEC62053-21,IEC62052-11.
♦Direct connection or through CT or PT & CT.
♦Four LED respectively indicate 3 phase,impulse.
♦Three phase power supply,there is no infection on measurement when loss one or two phase.
♦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.
