Product Description
This series meter has all the functions of SFDB series digital programmablemeters. It can measure almost more than 30 electrical parameters including of three-phase voltage, three-phase current, active power, reactive power, apparent power, frequency, power factor and 4-quadrant energy etc; It displays through 3-row 4-digit or 2-row 6-digit LED nixietubes or LCD screen. It is added with keyboard parameters such as alarm and transmitting output object, alarm delay time, display object and cycle display time and 2-channel electric energy pulse outputs, 4-channel switching value input and 4-quadrant energy measuring functions. The alarm(or switching value)output and transmitting output can enlarge to four channels.

Basic Parameters:

Input Parameters:

Rated voltage: AC 57.7V, 100V, 220V, 380V

Rated current: AC 1A, 5AFrequency range: 45~65Hz

Input network: 3-phase3-wire, 3-phase4-wire

Accuracy of measurement:

Voltage, current, active power. Reactive power, apparent power: ± 0.5%

Frequency: ± 0.1Hz Power factor: ± 0.01PF

Active electric energy: ± 0.5% reactive electric energy: ± 2.0%

Start: On the condition of rated voltage, reference frequency and COSΦ =1.0,

When load operational current is 0.001In, it can start and measure

The electrical quantity continuously.

Creep: When exerting 115%rated voltage and no current in the current

Circuitry, the instrument is with no electrical quantity accumulation

And pulse output.

Output parameters:

Pulse output: Open-collector optical coupling output, open-collector voltage

VCC≤ 48V, current Lz≤ 500mA

Pulse constant: 10000imp/kWh or 10000imp/kvarh. The meaning is: The

Pulse output 10000imp when the meter accumulate to

1kWh, it stresses that, 1kWh is quadratic electric quantity

Data of elecric quantity. Under the cndition of PT and CT,

The N pulse data responding the primary electric

Energy=1kWh× PT ratio× CT ratio

Alarm(or switching value)output: 4-channel relay normally open contact

Output, 30VDC/1A, 240VAC/1A(resistive load)

Switching value input: 4-channel dry contact(built-in+5V source)

Analog quantity transmitting output: Can provide4-channel outputs at the same time

Output range: DC 0~20mA/4~20mA programmable

Accuracy: ± 0.5%

Overload: 120% actual output, Max current is 24mA

Load: ≤ 400Ω

Communication interface: RS485 serial

Communication, applying MODBUS_RTU communication protocol
