I.Function and Feature

1.Wide load range ; high accuracy , reliability and sensitivity; low power loss.

2. Bi-directional measuring, accurately measure the active energy of both forward and reverse power.

3.Passive pulse output interface with optocoupler isolation.

4. Infrared communication interface. Baud rate is fixed at 1200.

5. RS485 (Optional ). Baud rate is 1200(DL/T645)and 4800(MODBUS), but it can be set at1200,2400, 4800 or 9600.( This function is optional.)

6. The meter uses LCD in a clearer display and nicer appearance.The total consumed energy is displayed in the top line, while the other items of constant,meter NO., voltage , current,power, power factor and frequency are displayed in the lower line in turns with an interval of5 second .

7.Anti-theft ,Anti-Tamper

3 Starting: when reference voltage, reference frequency and power factor is 1.0,  the meter of class 1 under 0.4%Ib,  the meter can start and do measurement normally.          

4 No load running: the meter has anti-shunt running logic circuit. when voltage circuit plus 1.15 times reference voltage, and there is no current in current circuit, the test output of meter is supposed not to have more than one pulse.

5 Power consumption:≤2W(10VA)

6 Environment condition

standard working temperature:-25℃~70℃    

limit of working temperature:-25℃~80℃

note: Special requirement of working temperature limit:-40℃~80℃
