Key Specifications & Feature
PBC-SFDBE-96TY Multifunctional Network Power Instrument
1.Functions
This series meter has all the functions of SFDB series digital programmable meters.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 eletric 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.
2.Model and Specification
3.Basic Parameters
Input Parameters:
Rated voltage:AC 57.7V,100V,220V,380V Rated current:AC 1A,5A Frequency range:45~65Hz Input network:3-phase3-wire,3-phase4-wire
Accuracy of measurement:Voltage,Current,Active&Reactive power,apparent power:±0.5% Frequency:±0.1Hz Power factor:±0.01PF Active electric energy:±0.5% Reactive electric energy:±2.0%
Stasrt: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 to1kWh,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 provide 4-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
