    Description

    ND10, Inexpensive 3-Phase Panel Multimeter, 96 x 96mm

    The ND20Lite meter from LUMEL is a digital programmable panel meter designed for the measurement of single-phase power network parameters (2-wire network) and 3-phase, 3,4-wire network in balanced and unbalanced systems with the simultaneous display of measured quantities on a LCD display.
    The ND20Lite enables the control and optimization of power electronics devices, systems and industrial installation operations.
    The meter ensures the measurement of: RMS values of voltage and current, active, reactive and apparent power, active, reactive energy, power factors, frequency, 15, 30, 60 minutes? mean active power, THD (Total Harmonic Distortion). 
    Additionally, the current value in the neutral wire is calculated. Voltages and currents are multiplied by given voltage and current ratios of measuring transformers. Indications of power and energy take into consideration values of programmed ratios.
    The value of each measured quantity can be transmitted to the master system through the RS-485 interface. The relay output signals the overflow of the chosen quantity, and the pulse output can be used for the consumption check of 3-phase active and reactive energy.
    The meter has a galvanic separation between respective blocks:
    - supply voltage 
    - measuring inputs
    - voltage and current inputs
    - RS-485 output
    - pulse output
