North Atlantic iPM DSP-based intelligent power monitor & control unit

18 January, 2010 | Supplied by: Unitronix Pty Ltd

North Atlantic Industries (NAI) has released a next-generation, DSP-based intelligent power monitor and control unit. The model iPM monitors single- or 3-phase wye or delta connected power lines for voltage, frequency, phase sequence, THD and DC component. When any of these parameters are outside of their preprogrammed limits, the iPM internal 10 A relay opens and disconnects the power from the load. The device has a universal input voltage range of 80 to 230 RMS and a universal input frequency range of 47 to 800 Hz. It includes a background self-test capability that constantly monitors the health of the unit.
