C-TRAN-100A, HOBUT

C-TRAN-100A, HOBUT

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. Parameters measured: • Phase Voltage (V) • Line Voltage (V) • Phase Current (I) • Frequency (Hz) • Active Power Per Phase (W) • System Active Power (W) • Reactive Power Per Phase (VAr) • System Reactive Power (VAr) • Apparent Power Per Phase (VA) • System Apparent Power (VA) • Import Active Power (W.h) • Import Reactive Power (VAr.h) • Apparent Energy (VA.h) • System Power Factor (P.F.) • Amp Demand (Ad) • Maximum Amp Demand (Max.Ad) • Import Watt Demand (Wd) • Maximum Watt Demand Import (Max.Wd) • VA Demand (VAd) • Maximum VA Demand (Max. VAd) • Neutral Current • Hours Run—Voltage based
