Overview
The model UMA & UMV series, are designed under micro base, and it also designed for general performance ot accept Ac input signals
& convert AC to DC of average responding to scale rms reading. Model UMAR & UMVR series, a true-root-mean-square conversion unit,
are able to measure a distorted sinusoidal with harmonics or periodical of non-sinusoidal signal.
The unit type of ration input ranges are defined to accept a secondary signal from PT or CT & calibrated to primary reading & the
named type of input ranges just directly follow inputs as a display reading. The designed specifications of the units, truly a real
power system design, compliant ANSI-IEEE & IEC, VDE those standards providing full protection for surge intrusion & unusual over
input to assure reliable operation.
