An AC energy meter is a specialized device engineered to collect a variety of AC power or energy data for a single load or an entire system. Generally installed adjacent to an electrical panel or within switchgear, an AC energy meter may continuously gather data to provide detailed insight into consumption patterns, load profiles, and system performance. In addition, some AC energy meters also measure power quality parameters, allowing facilities professionals to stay ahead of harmful PQ issues, protect sensitive equipment, and reduce downtime.

POWER QUALITY MONITORING

Key Specifications:

• IEC 61000-4-30 Class S compliant.

• Capture sags, swells, and other critical events with a timestamp and triggering information

• Supports logging individual harmonics up to the 63rd

• Save up to 50,000 power quality events

• All events are stored in non-volatile memory

• Gain insight into power quality by capturing waveforms when voltage sags or swells occur

The Acuvim IIW can record voltage & current waveforms. The instrument supports a settable triggering condition and data can be stored for later analysis.

WAVEFORM CAPTURE

Key Specifications:

• Trigger a waveform from voltage sag or swell, over current, or switch status digital input

• Record 100 groups of voltage & current waveform data at a sampling rate of 64 points per cycle

• Data is saved in the COMTRADE format (when using AXM-WEB2)

The Acuvim II meter monitors over 400 essential measurement parameters with superior accuracy. Ideal for revenue submetering projects, such as tenant billing or cost allocation, the Acuvim II meter's revenue grade accuracy delivers precise, reliable data in critical applications
