Handbook of Transducers
Application
Current transducer measure power and monitor operations as well as monitoring changing products variables.

Feature of Current Transducer:
Three ranges per unit reduces inventory by selecting jumper or none. No field adjustment necessary, factory calibrated. Average measurement is equivalent to True RMS for pure sine waves for the 0~5V, 0~10V no need power supply. 4~20mA series True RMS measurement for sine waves or variable frequency drives for the series Input or Output isolation through current transformer solid-state reliability.

Power supply: 15~42 V DC at sensor(loop powered)
Operating Temperature: -30 degrees~70 degrees Centigrade
Input Current Ranges(3 selectable ranges): 0-10/0-200/0-50 AMPS or 0-50/0-100/0-200 AMPS.
Operating Humidity: 0-95% RH, non-condensing.
Frequency: 40~400Hz
Approvals: UL & cUL CE & RoHS
Maximum Input

Current:
10/20/50 AMP ranges - 80/120/200 AMPS continuous
50/100/200 AMP ranges -175/300/400 AMPS continuous
Protection Circuit Reverse voltage protected and output limited.

Wiring Solid Core: Barrier strip AC Conductor Hole
Split Core: Enclosure Material UL 94 V -0 flammability rated, ABS plastic housing.
Output Signal & Accuracy: 4-20 mA represents 0-100% of current span, better than ± 1% FS on all three ranges.

Risk of Shock
Disconnect power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electrical shock and may result in severe personal injury or death. Ensure all installations are in compliance with applicable electrical codes and that the installation is completed by qualified installers familiar with the standards and proper safety procedures for hegh-voltage installation. Never rely on status indicating devices only to determine if power ispresent in a conductor. Ensure the range selection jumper is installed in the correct position for the current being monitored.

Attention:
1 0-5V, 0-10V output do not need power supply.
2 Excessive current can damage the sensor. See below for information on setting the jumpers:
A). Install the Split-Core over the conductor to be monitored and close the sensor until it latches, ensuring that the two halves are properly aligned.
B). Operation of the sensor will be impaired, if any dirt particles prevents good contact between the core pieces when the divice is closed, keep the sensor clean when it is opened.

Mounting:
Mount the switch in a suitable location using the two mounting holes in the base of the unit. The conductor may be looped more than once through the sensor to multiply the sensitivity but this also divides the maximum currents. For example, on the 0-200 AMP scale, if the conductor is looped through twice, the maximum current will be 100 AMPS now. Connect the output circuit to the two screw terminals using ring or for type terminals. Note polarity as indicated on the device label. To allow field calibration, all devices have easily accessible calibration pots. The devices may be calibrated to custom.
