Power quantity monitor

The Power Standards Laboratory PQube power quantity monitor measures voltage disturbances and steady-state trend values and stores the data on an SD card.

The device can be built into equipment and switchboards to provide a quick source of data to assist in resolving equipment malfunctions and operating parameters in applications where continuity of supply is important.

Using the optional ethernet module, the device can email disturbance-event notifications with time-stamped RMS and waveform event pictures.

The modular device mounts on standard DIN rails and can be powered from 24 VAC, 24 VDC and 48 VDC in standard format, or a 100-240 V 50/60 Hz optional module.

Voltage monitoring input connections can be single-phase, three-phase delta, three-phase star/Y and split-phase with nominal input voltages between 100-600 VDC 50/60/400 Hz. Voltage disturbances recorded include sags/dips, interruptions, frequency variations and impulses to 1 µs.

One digital and two ±60 V analog inputs and one relay contact output are provided as standard.
