Single / three-phase energy analyzer suitable for harsh environments. With white / blue backlit graphic LCD display. Measurement of the THD on voltage and current, of the neutral current, maximum and minimum voltage, maximum current and power and of the active energy of each phase. Four operating time counters of the monitored load. 2 calibration LEDs. RS485 interface. 2 calibration LEDs. RS485 interface. 2 analogue outputs 4-20mA or 0-20mA. Galvanically isolated, active, self-powered (for loads up to 250 Ohm; for higher and up to 750 Ohm external 12Vdc power is required). The refresh of the output signal is done at max. every 200 mS. Each of the two outputs can be combined with any of the measured parameters. Size 6 DIN rail modules. 230Vac power supply. Complies with EN 50470-1 + EN 50470-3.
