This device is a panel mount or flush mount power meter with a 96mm by 96mm bezel size having 3 rows of bright red 4 digits 14.2 mm height LED display. The meter measures active energy as per accuracy class Class 1.0 complying to IEC 62053-21 standard with sampling rate of 64 samples per cycle. Able to measures all three vectors of power and energy such as Active, Apparent & Reactive beside Voltages, Current, Frequency and Power Factor. Plus the total Harmonic Distortion and Individual harmonics up to 15th Harmonic order. The meter will function in either 50Hz or 60Hz network frequency and accepts universal control power voltages ranging from 44 to 300 V Line to Neutral AC or DC voltages. Rated current for this meter is either 1A or 5A input. it supports up to 13 different types of wiring schemes under Single Phase, Two Phase or Three Phase configuration types. The range of measurement voltage between Phases is 35 to 480 V Line to Line AC at 45 to 65 Hz while it is 20 to 277 V between Line and Neutral. It is having RS485 communication port over Modbus RTU protocol. Product dimensions are as follows: width 3.78 in (96 mm), depth 2.16 in (54 mm), height 3.78 in (96 mm) and product weight 10.58 oz (300 g).
