3. Main parameters
3.1 The starting current
Connected by CT: Active Class 1 .0is 0.002In.
Direct connect: Active Class 1 .0is 0.0041b.
3.2 Latent movement: No current is applied to the current line, 1 15% of the reference voltage is applied to the voltage line, and the test output of the electric energy meter does not produce more than one pulse within the time limit specified by the specified standards.
3.3 Power consumption
Voltage loop power consumption≤2W/10VA, current loop power consumption≤4VA
3.4 working voltage range
Normal working voltage: 0.9~1.1 reference voltage
Limit working voltage: 0.7~1.2 reference voltage
3.5 Environmental conditions
Standard working temperature is -25°C~+55C
The ultimate operating temperature is - -40°C~+70C
Annual average relative humidity:<75%
3.6 Measurement function: Measure the voltage, current, active power, reactive power, apparent power,power factor and grid frequency of the combined phase and each phase A, B and C.
3.7 Alarm function
When the phase is missing, the alarm indicator light will light up and the corresponding voltage symbol on the LCD will flash.
When the battery voltage is low, the alarm indicator lights up and the corresponding battery symbol on the LCD flashes.
3.8 Communication function
Infrared communication is available. Two- way RS485 communication completes programming settings and meter reading. Three- -way communication is completely independent. The RS485 baud rate can be set (bps): 1200, 2400, 4800, 9600.
Communication port 4851 complies with DL/T645- -2007/1997 specification.
Communication port 4852 complies with MODBUS-RTU protocol
