DITEL$>L U M E L ND20 - METER OF NETWORK PARAMETERS • Measurement of power network parameters in 2,3 or 4- wire balanced and unbalanced systems. • High accuracy class. • Indications considering values of programmed ratios. • Harmonics of voltages and currents (selectively). • THD factors for currents and voltages. • Profile of 15, 30, 60-minutes' power (9000 measurements). • Watt-hour meter for the selected harmonic. • Backlit LCD 3.5" screen. • Protection grade from the frontal side: IP65. • Digital transmission to the master system through the RS-485 interface (MODBUS). • Configurable analog, alarm and pulse outputs (energy). • Configuration of displayed pages. Measurements, monitoring, recording of network parameters and energy. measured quantities and measuring ranges * Depending on the set tr_U ratio (ratio ofthe voltage transformer: 0.1...4000.0) and tr_I ratio (ratio ofthe current transformer: 1...10000) r - of the range mv - of the measured value
