1. General
        ACR330ELH/M is one of multifunction analyzers, and it can measure all the data of electrical network. At the same time, they can measure more than 31th harmonics and display the  harmonics by bar graphic and by wareform. According to crest factor, K factor, THFF etc., the user can analyze the power quality of electrical network.

         It complies EN 61326:2006 and EN 61010-1:2001 and RoHS Directive 2002/95/EC.

           
- Communication and programming via optical interface, or remotely via RS485 output
- Energy: measurement import kWh, kvarh, kva and export kWh and kvarh in class 0.5
- Display of harmonics by order to 31st
- Display of harmonics by bar graphic and by wareform
- Up to 4DI & 2DO configurable, one DO can be used as Alarm.
- 16 SOEs
- Possibility of upgrading the embedded software via the optical interface
- Graphic display: Fresnel diagram, harmonics in bar graph form, U, I displayed as gauges
