C-TRAN COMBINED 3 PHASE CT
& MULTIFUNCTION TRANSDUCER
WITH RS485 OUTPUT
DESCRIPTION
The C-Tran is combined 3 phase multifunction AC
Power transducer and 3 phase current transformer.
The C-Tran is fully programmable through either of
the two communication ports
APPLICATION
The C-Tran can replace traditional multifunction
meters and 3 separate current transformers with an
all in one combined product with RS485 output
PARAMETERS MEASURED MEMORY
• Phase Voltage (V) All data including energy registers, current and voltage
• Line Voltage (V) ratios and calibrated data is stored in a non volatile
• Phase Current (I) eeprom.
• Frequency (Hz)
• Active Power Per Phase (W) CUMMUNICATION
• System Active Power (W)
• Reactive Power Per Phase (VAr) Port 2:
• System Reactive Power (VAr) The main communication port.
• Apparent Power Per Phase (VA)
• System Apparent Power (VA) It uses the popular Modbus protocol to retrieve
• Import Active Power (W.h) measurements and to change the transducers operating
• Import Reactive Power (VAr.h) parameters. It enables the connection of a host
• Apparent Energy (VA.h) computer, PLC, RTU, Data Logger etc.
• System Power Factor (P.F.)
• Amp Demand (Ad) Port 1:
• Maximum Amp Demand (Max.Ad) This port has a fixed data format, It can also retrieve
• Import Watt Demand (Wd) measurements and set the transducer operating
• Maximum Watt Demand Import (Max.Wd) parameters. Only the baud rate and endian format can
• VA Demand (VAd) be changed on this port.
• Maximum VA Demand (Max. VAd)
• Neutral Current Can connect with M850-LCM display with this port
• Hours Run—Voltage based
PROGRAMMING
ACCURACY Setup and monitoring software is available from
The accuracy of the C-Tran is Class 0.2 to IEC688 over Our website www.hobut.co.uk
the range 10% to 120% In, and for voltages from
100V to 120% of nominal input.
For Active and Reactive energy the accuracy is 1% of
the reading to IEC 1036.
The accuracy of the current transformer is Class 1 for
the range 10% to 120% of nominal input.
Our policy is one of continuous development and therefore specifications may change without notice.
