The A/CTA-VFD 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. All A/CTA-VFD units have a true RMS output and have jumper selectable input ranges (except for the 0 to 5 Amp range).
The A/CTA-VFD series current sensors are fast acting and extremely accurate from 1 to 100% of the Full Scale Output. All of the A/CTA-VFD series current sensors are factory calibrated using a NIST Traceable standard and shipped with the jumper placed in the largest jumper selectable range. They must be externally powered using a +12 to 30 VDC power supply.
The A/CTA-250-VFD Series has jumpers for 0-100, 0-200, and 0-250Amps.
Solid core current sensor, loop powered, 4-20mA average output, jumper selectable range (0-100A, 0-200A, 0-250A)
