Three-phase multifunctional energy meter (guide rail type)

Product Features

■The three-phase intelligent rail meter measures active and reactive power in both forward and reverse

directions. It simultaneously monitors A, B, and C phase voltages, currents, active/reactive power,

power factor, grid frequency, and total power consumption, with maximum demand recording

capability. The meter stores cumulative data for active/reactive power, forward/reverse total, peak,

valley, and flat periods, with the multi-rate billing function available only in high-capacity models.

■You can set two time zones and two schedules per year, eight daily periods and four rates:

peak, peak, flat and valley. The minimum interval between periods is 1 5 minutes.

■The system features data wheel display and data key display functions. Users can access voltage, current,

power factor, frequency, active power, reactive power, forward/reverse active energy, and forward/reverse

reactive energy through panel buttons. If no button is pressed within 8 seconds, the system automatically

switches to 4-second wheel display mode.

■Optional display of maximum demand for U, I, P, and Q, along with total peak, valley, flat, and off-peak power consumption for active and reactive power.

■Features active and reactive power pulse outputs for meter calibration and remote energy

collection. The passive opto-isolated output port delivers a pulse width of 80ms ± 20ms.

●The clock error is less than 0.5s per day, with automatic switching of calendar, timing, and leap year.
