PD280Z Series Multifunction Power Meter

PD280Z series multifunction power meter can measure all power parameters in three-phase power network such as: three-phase voltage (phase/line), three-phase current, active power, reactive power, power factor, grid frequency, and four-quadrant electric energy metering. The meter not only has all functions of PD652E such as standord power pulse output, RS485 communication interface, but also can be an optional of 1-6 channels of switch input lremote signll, 1-4 channels of relay output (remotel, 1-4 channels of analog transmission outputl4 20mA. etc. The meter con be input directly from voltage and current transformers, and PT and CT ratio can be set anywhere. Display progrommable cycle/switch display mode.

Multifunction Harmonic Meter "Function and Product Features”

Measure all power such as U,1. R, 0.s, PF, F. etc. in the three phase power grid, and carry out demand satistis;
