Overview
Model MWF & MKF series, programmable watt & var meters, are specially designed for solving many variables
of CT & PT Ratio problems & having very convenient performance in measuring active & reactive power. The unit
uses Time division multiplier principle of a very acurate converting untion & also of a real power detection, able to
measure distorted input signal.
The unit basically is a 4-1/2 digits design, under an efftive limitation for different phases & wires system the
maximum defined reading ranges as following;
- 16000 counts-MWFZ/MWFZ2/MKFZ/MKFZ2/MWFQ/MWFQ2/MKFQ/MKFQ2............3 phase 4 wire system.
- 11000 counts-MWFY/MWFY2/MKFY/MKFY2............3 phase 4 wire system.
- 5500 counts-MWFX/MWFX2/MKFX/MKFX2............1 phase 2 wires system.
The ratio setting for PT x CT ratio of a digital type, first 3 effective digits selection, fits over 99% application in all
systems. With proper unit annunciator & decimal selection, the unit can get a required primary reading without any
recalibration process.
The designed specification follows ANSI-IEEE & IEC, VDE standards providing full protection for surge intrusion
& unusual input over, assuring reliable operating.
