The Acuvim II series is a family of high-end multifunction power and energy meters made by Accuenergy for monitoring and controlling power distribution systems. Voltage inputs have a nominal full scale of 400 V line-to-neutral and 690 V line-to-line. Current inputs come in 5 A and 1 A options, including 333 mV and Rogowski coil types. Active energy accuracy is class 0.1s under IEC 62053-22 and class 0.1 under ANSI C12.20. Harmonics are resolved up to the 63rd on 50 or 60 Hz types. The standard RS485 port carries Modbus RTU and DNP 3.0. Optional modules add Ethernet with Modbus TCP, BACnet IP or MS/TP, Profibus DP, and IEC 61850 2nd edition. The meter analyzes power quality, covering harmonics, crest factors and unbalance. The IIW model also logs power quality events such as sags and swells. It is listed to IEC 61010-1, UL 61010-1, IEC 61557-12, IEC 60068-2, CE and RoHS, and it works with the AXM-WEB2 Ethernet module. The brochure states a five-year warranty.

c22 drafted · lead nominal 400 V

Conditions: Voltage input nominal full scale, line-to-neutral (+20%)

review note: possible conflict with c23 (same source; check the conditions)

c24 disputed 100–415 V

Conditions: Auxiliary power supply option P1, AC (also 100-300 Vdc)

review note: support check: partial - P1 is 100~415Vac and 100~300Vdc, but the passage does not call it 'nominal voltage' of the auxiliary supply; it's a supply range, which is acceptable, though it matches closely.conflicts with: Accuenergy Acuvim II power meter (c23)
