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.
The Acuvim II is a premium power and energy measurement instrument capable of delivering superior results across a wide range of AC measurement applications. With a variety of customizable options including form factor, current sensor choices, & communication protocols, easily configure the meter to match any project objective.

Designed for Acuvim II Series energy meter’s 96mm by 96mm display. Crucial in harsh environments, it increases the IP environmental rating of a meter's display to IP66 or NEMA 4X.
This plug-and-play USB to Serial RS485 Converter is designed to provide a convenient and reliable connection from Acuvim II meters to other devices with a USB port.
Adapter provides the option to mount the Acuvim II meter on a DIN rail either at a horizontal or vertical angle. It is easily secured to the meter or AXM modules.
Pre-configured, pre-wired panel solution is ideal for on-site installations need to meet regional regulatory safety and environmental compliance. All panels are quality tested to be reliable and fault-free.
The Acuvim II power meter support multiple current inputs: 5A/1A, 333mV and Rogowski Coil, and 80mA/100mA/200mA. They are among the industry’s highest accuracy metering CT offering exceptional value.
A maximum of three modules may be attached to the meter at the same time.
The meter supports single phase systems. Single phase 2-wire and single phase 3-wire are supported. The wiring configuration should be set to 1LN, 1CT for single phase 2-wire and 1LL, 2CT for single phase 3-wire systems.
Yes, you can use a jumper to power the meter as long as the voltage input is within the meter's control power limit of 100-415Vac for P1 meters and 20-60Vdc for P2 meters. V1 on the voltage input can be jumped to "L" on the meter's power supply terminal and V2 of the voltage input can be jumped to "N." NOTE: If there is a neutral in the system you can jump the neutral from the voltage input to the ‘N’ terminal of the meters power supply, and use one of the voltage inputs to connect to 'L'.
The LCD screen refresh rate is 1 second while the Modbus data updates in the registers at a 100ms refresh rate.
Yes, the Acuvim II meter supports SunSpec. The SunSpec registers can be found in the download section of the website as well as in the meter's user manual.
Yes, the Acuvim II can be used to monitor 400Hz systems. In addition, the meter can automatically detect and adapt to the frequency of the electrical system.
The meter takes 512 samples per cycle.

Yes, the meter may be powered up using only one voltage wire (V1) and the neutral wire (Vn). This may be accomplished by jumping the voltage phase wires.
We do not recommend extending over 50m. If you choose to extend the CT leads according to this guideline, we suggest that using a twisted pair of cables. Adding shielding is also recommended best practice.
