Introduction
Infinity is a digital energy meter for use in three phase electrical
systems as well as sub-metering applications. The design of this
meter is based on proven microcontroller technology with front
end ASICs, resulting in compact and accurate energy metering.
The accuracy of the meters is maintained even under severely
distorted waveform conditions which occur due to harmonics in
the system.
Infinity is the advanced model with bright 16X1 LC display having
optional features like RS485 port, dual source measurement and
whole current measurement up to 60A.
