DSM866C Three-phase Four-wire Electronic Active Energy Meter (LCD Display)

APPLICATION

DSM866C 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 cover is made of non-transparent ABS or transparent PC /AS plastic.Meter base is non-transparent

ABS or PC plastic.Meter terminal block is made of bakelite which is moisture-resistant, fire-retardant, high

temperature molded.

♦LCD display.May select cyclometer display.

♦Adopts ATT7030A chip,the key components and part all adopt long life type .

♦Adopts the newest electric dedication 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.
