C-TRAN-250A, HOBUT C-TRAN 3 Phase No Display Digital Power Meter, Измеритель мощности

C-TRAN 3 Phase CT with In-built Power Meter

The C-Tran is a combined 3 phase multi function AC power transducer and a 3 phase current transformer in one. The meter is fully programmable through either of the two communication ports. The C-Tran can replace traditional multi function meters and 3 separate current transformers with this all-in-one product with RS485 output.

• RS485 output
• Non-volatile EEPROM memory for storing energy registers, current and voltage ratios and calibrated data
• 2 communication ports
• Accuracy class 0.2 to IEC688
• Multiple installation options
• 3 phase current options; 100A (914-5357), 160A (914-5351) and 250A (914-5360)

Communication Ports

Port 1:
The port has a fixed data format that can also retrieve measurements and set the transducer operating parameters. Only the baud rate and endian format can be changed on this port.

Port 2:
The port is used as the main communication port. It uses Modbus protocol to retrieve measurements and change the transducer operating parameters. It also enables the connection of a host computer, PLC, RTU or Data logger.
