Description

ProTAC-M2 is a digital meter that assesses the harmonics and displays the measurement values of zero-/negative-phase elements. It is a multifunctional product that monitors the active and reactive power as well as the voltage and current of a system.

Features

Rate Value: voltage (phase voltage, interphase voltage), current (phase current, N-phase current), power factor, frequency
Power: active power (constant/reverse), reactive power (inductive/capacitive), apparent power
Energy: active energy (constant/reverse), reactive energy (inductive/capacitive)
Minimum/Maximum Value
Voltage (phase/interphase), current (each phase/total)
Active power (each phase/total), Reactive power (each phase/total), apparent power (each phase/total)
Energy Demand
Current, active current (each phase/total), reactive current (each phase/total), apparent current (each phase/total)
Average value measured over a selected timeframe (1~60 minutes, minute unit selected)
Digital Input: 2 points (transmits data to superordinate system via ModBus communication)
Pulse Output: 2 points (output of different energy pulse)
Communication speed of 2,400~38,400bps via standard ModBus communication protocol (RS485)
Maximum number of connectable equipment: 31 (247 when a repeater is used)
Main configuration parameter is downloadable from a remote PC
Able to substitute the conventional analog method of wide-angle A-meter and V-meter types, A/S, V/S, and conversion devices (A/V/Watt) and minimizes the man-hours for internal wiring
Adopts a draw-out terminal block that allows maintenance to be performed without disconnecting the actual wires
Features a compact size of 96x96 and screw-free repair.
