Single Phase Multifunctional Standard Meter LY311
Introduction
LY311 single-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 single-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 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 single-phase AC voltage, current and power.
- Equipped with RS485 communication interface, it can directly communicate with PC on-line.
- Measurable up to 120% of the volume limit.
- Long/short terminal cover
