N30P DIGITAL PANEL METER • Measurement of single-phase network parameters: voltage, current, active, reactive and apparent power, cos, tg, , frequency, active, reactive and apparent energy, 15 minutes’ active power, 10 minutes’ voltage, 10 seconds’ frequency. • Three-colour display (14 mm high), in three intervals of the measured value. • Meter programming from the keyboard or through the RS-485 interface by means of the free delivered LPConfig program. • Four alarm outputs with signalling by LED diodes, operating in 6 different modes. • Storage of minimal and maximal values for all measured quantities. • Conversion of any measured value into a 0/4...20 mA or 0...10 V analog signal. • Storage of minimal and maximal values for all measured quantities. • Firmware updating (option).
