Overview
The Voltage Output Analog Current Sensors are designed for use in any AC current
monitoring application in which you are looking to monitor a particular piece of
equipment for proper operation. All voltage output current sensors use an "Average"
current measuring method and should be used in applications where a pure
Sinusoidal AC waveform that has very little or no distortion/noise on the conductor
being monitored. Applications may include monitoring a resistive type load such as an
incandescent light bulb or heating element as well as any single speed linear load.
Voltage Output current sensors are available in both solid and split-core versions
which also includes a Patented 35 mm Din Rail mounting foot for easy installation in
panel mount applications. The solid-core versions are a great choice for new
installations or OEM applications in which cost sensitivity, lower trip points and
environmental issues like dust and moisture may be of concern. The split-core version
of the current sensors work great in retro-t applications and for use on service technicians vehicles since one or two parts
will work in most applications and can be easily installed without disconnecting any wires. For best results, the voltage
output current sensors should not be used in applications with switching power supplies or variable speed drives due to
the limited operating frequency range. In applications where variable speed drives or waveforms include distortion/noise,
Carrier recommends the use of the NSA-A/CTA2-RMS or NSA-A/SCTA2-RMS Series sensors where you need to supply
24 VDC power to the current sensors with a 4-20 mA signal. A 249 Ohm or 499 Ohm 1 Watt resistor can be used to
convert the 4-20 mA signal into a useable 1-5 or 2-10 VDC output signal at your building management system or PLC.
Applications: Load Trending, Single Speed Loads, Pumps, Compressors, Fans, Preventative Maintenance, LEED,
Project Justification (Calculating ROI), Process Control
