|
|
| The A/SCTA Series current sensors monitor the current flowing to electrical equipment or buildings. The magnitude of this current is then converted into a linear and proportional 4 to 20 mA output signal, which can be monitored by your Building Management, DDC, or PLC controller. The A/SCTA Series current sensors are available in either an Average or True RMS output version. All of these sensors have jumper selectable input ranges except for the 0 to 5 Amp input range. These current sensors should be used in load trending (current monitoring) type applications. The A/SCTA series current sensors are an excellent choice for retrofit or existing installations, since you will not have to power down the unit and disconnect any wires during the installation process due to the split-core design. The A/SCTA series current sensors are fast acting, reliable, and extremely easy to install. No din rail mounting clips are necessary, due to the unique design of the integral din rail mounting flange.

The A/SCTA series current sensors are fast acting and extremely accurate from 1 to 100% of the FSO (Full Scale Output). All of the A/SCTA series current sensors are factory calibrated using an NIST Traceable standard and shipped with the jumper placed in the largest jumper selectable range. In applications where the maximum current is larger than 250 Amps, ACI recommends the use of a traditional ratio:5 (5A) current transformer and the A/SCTA-5 for best results. The A/SCTA must be externally powered using a +12 to 40 VDC power supply. Due to the split-core design, it is extremely important to make sure to keep the mating surfaces free of dirt and debris. Failure to do so will affect the output accuracy and functionality of the unit.
All of the A/SCTA series current sensors come with a limited five year factory warranty. Please contact ACI for more information regarding this product.
