DTS866Three Phase Four Wire Electronic Active Energy Meter with RS485 Communication(LCD Display-DSM866CR)

APPLICATION

DSM866CR three phase four wire electronic active energy meter with RS485 communication,LCD display.

The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.

The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique,the key components and part all adopt long life type.

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

♦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 selete cyclometer display.

♦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.

♦There is a port of RS485 data communication.Standard configuration communication protocol complying with standard DL/T645-1997,can also choose any other communication protocol.

♦Six LED instructions phase,impulse,communication,etc.

♦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.

♦Directly connect operation or through CT or PT & CT.

♦Adopts high reliable and long-life electric components,hioverload,do not need to calibrate for long-term operation

♦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.
