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

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.

The iPM provides a serial RS-485 interface that allows real-time data readout of the monitored power parameters and the self-test status, as well as allowing external control of the state of the power relay.

With its full feature set, serial interface and compact design, the iPM is suitable for military and aerospace programs, including airborne, shipboard and ground applications. The unit is designed to meet the environmental requirements of MIL-STD-810C, the EMI requirements of MIL-STD-461 and the input transient requirements of MIL-STD-704E, when installed within the system.

The iPM is hermetically sealed and operates over a temperature range of -55 to +100°C.
