1. Introduction
The instrument is a panel mounted 96 x 96mm DIN Quadratic energy meter. It accumulates
Active energy, in three phase network.
The instrument also measures AC Voltage, AC Current, Frequency, Power, Power factor,
Phase Angle, Apparent Energy which can be accessed via Modbus. All voltage & Current
measurements are True RMS upto 15th harmonic.

Ultra high brightness LED display.
Down Up
It can be configured & Programmed at site for the
following :
PT Primary, PT Secondary 3 phase 3W or 3 Phase
4W system.
The front panel has two push buttons through which the
user can reset the energy & configure the product.
The front panel has Impulse red led, flashing at rate
proportional to measured power.
Its impulse rate is 3600impulses/kWh.
