TRANSDUCER OF 1-PHASE POWER NETWORK PARAMETERS WITH ETHERNET

DESCRIPTION OF TRANSDUCER OF 1-PHASE POWER NETWORK PARAMETERS WITH ETHERNET

The output signal is galvanically isolated from the input signal and the power supply.
P30P has programmable measurement and additional functions.
Programming parameters can be realized with the use of buttons, via RS-485 interface and free e-con software or Ethernet or any web browsers (see how it works: login – user, password – pass).

Programmable transducer P30P is suited for single-phase power line parameters measurement and converting them into standard D.C current or D.C voltage signal. Output signal is

galvanically isolated from input signal and power signal. Transducer uses 2×8 characters LCD.

Characteristics of P30P Transducer:

• conversion of measured values into an output signal on the base of the individual linear characteristic,
• one or two relay alarms with the n/o contact operating in 6 modes,
• 24 VDC 30 mA auxiliary power turned on/off according to program (optional)
• signaling of the set alarm values tripping,
• programming of alarm output and analog outputs reacting to the selected input value,
• real time clock with the clock power support function in case of the transducer power failure,
• input signal registration in the internal memory and SD/SDHC cards within the programmed time

intervals (optional),

• internal memory with 534336 record capacity,
• automatic decimal point set,
• set parameters display,
• password protection for the input parameters,
• compatibility with RS-485 interface with MODBUS protocol, in RTU mode,
• measurement averaging time programming,
• SD/SDHC card use – FAT and FAT32 system compatibility,
• Master RS-485 mode – 1 device query,
• Ethernet interface10/100 BASE-T (optional)

◦ protocol: Modbus TCP/IP, HTTP, FTP,

◦ services: web server, FTP server, DHCP client

The values measured and calculated by the transducer:

 phase voltage

 current

 active power

 reactive power

 apparent power

 active power factor

 reactive power factor (cosφ)

 active power averaged (e.g. 15 min)

 reactive power averaged (e.g. 15 min)

 current averaged (e.g. 15 min)

 value of the cosine of the angle φ

 active power:

– import:

– export;

 reactive power:

– capacitve;

– inductive;

 apparent energy

 frequency

 time

 THD U, THD I

 minimum and maximum values for:

– phase voltage;

– current;

– active power;

– reactive power;

– apparent power;

– active power factor;

– reactive power factor;

– frequency;

– mean active power;

– mean apparent power;

– mean current.

Transducer allows for the use of external transmission and measurement conversion included in the measurement and calculation of all measured values. Value upgrade time does not exceed 1 second. All values and configuration parameters are available through RS-485 and Ethernet (Modbus protocol) (option).
