Current monitor
1 x 110-240 VAC, 3 x 120-480 VAC, 50-60 Hz, +/- 10 VDC Cognito Quam Electrotechnologies Ltd

The PFCDxx power factor current detector measures the apparent and either the active or reactive current in a single- or three- phase power line to respectively produce a set of two 10 VDC analog signals. The two outputs can then be used by a PLC or other controlling device to calculate line power factor as well as monitor the applicable active or reactive current characteristics. It is very simple to install and adaptable to all power factor compensation applications.

The PFCDxx measures the power factor related currents in most standard single phase (1x120 V/60 Hz, 1x230 V/50 Hz, 1x240 V/60 Hz) or three phase (3x120V/60 Hz, 3x240V/60 Hz, 3x400V/50 Hz, 3x480V/60Hz) line systems and produces a unipolar 0-10 VDC signal representing the apparent current and a bipolar ±10 VDC signal representing the active (PFCDxA) or reactive (PFCDxR) current. The current is picked up with a current transformer (CT) in one of the phase lines with a response time of about 3 seconds.

The PFCDxx's versatility and fast response make it particularly suitable for integrating into systems such as:
* Power factor measurement and compensation,
* Power factor and energy flow measurement,
* Reactive current measurement and compensation, and
* Line current measurement and overload/underload protection.
