Three Phase Multifunctional Standard Meter LY331 Accuracy class 0.05
Introduction
LY331 three phase multifunctional standard meter is a new generation of multifunctional standard meter produced by our company, which adopts new hardware and software design, and can simultaneously measure three phase voltage, current, frequency, phase, active power, reactive power, apparent power, active power, reactive power, and can measure high-order harmonic distortion (up to 64th harmonic) and the characteristics of the hardware gearshift of the small current, which makes the whole machine with a wider measuring range and a wider application range. It has a wider measurement range and a wider application range.
- Electrical energy errors can be checked.
- Real-time oscilloscope display curves are available U(t), I(t).
- It can measure the stability of three phase AC voltage, current and power.
- Equipped with an RS485 communication interface for on-line communication with a PC.
- Measurable up to 120% of the volume limit.
