ND10, Inexpensive 3-Phase Panel Multimeter, 96 x 96mm
The ND10 meter from LUMEL is characterized by high measuring accuracy, easy to read backlit LED display and an attractive price.
It measures the mains network parameters in symmetrically and asymmetrically loaded 4-wire systems, with simultaneous display of the measured variables and digital transmission of their values.
The meter enables the control and optimization of electrical devices, industrial systems and industrial plants.
The ND10 is suitable for measuring: RMS values of voltage and current, active, apparent and reactive power, active and apparent energy, power factors, frequency as well as 10-, 30- and 60-minute averaged active power and THD (Total Harmonic Distortion). .
In addition the RMS value of the current in the neutral conductor is calculated from the vectors of the phase currents. The voltage and current values are multiplied by the set voltage and current transformation ratios of the transducers. The power and energy indicators take into account the programmed transformation ratios.
The value of eache measured variable can be transferred to a main system via the RS-485 interface.
The relay outputs signal if selected measured values have been exceeded.
The pulse output is intended for controlling the consumption of tree-phase active engergy.
The meter is equipped with detection and signaling of wrong phase order.
The ND10 is powered by the measuring circuit input voltage.
It has a galvanic isolation between individual blocks:
- voltage and current inputs
- RS-485 output
- pulse output
Characteristics:
- Measurements of up to 52 mains network parameters
