Features
? Measurement of single-phase network parameters: voltage, current, active, reactive and apparent power, cos, frequency, active, reactive and apparent energy, 15 minutes active power, 10 minutes voltage, 10 seconds frequency
? Three-colour display (14mm 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 LP config 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…20mA or 0…10V analogue signal
? Storage of minimal and maximal values for all measured quantities
? Firmware updating (option)
特性
