Unique Features

High accuracy over a wide dynamic operating range
Available in Accuracy Class 1.0 and 0.5
Utility meter cross check
Two sets of Integrator registers, one for current and other one for last cleared values. The latter facilitates cross check of electricity bills with data recorded for the corresponding billing period, comparison between previous month and current month, etc.
Measures Total Harmonic Distortion & Individual Harmonic up to the order of 15th for both current and voltage, per phase – a useful aid to check the power quality.
Two Digital Inputs for status monitoring
Whetting voltage with nominal range of 22 to 26V with allowable load of 8mA
Import / Export option enables monitoring of bi-directional power flow – useful when in-house generation is run in parallel with the Grid.
User programmable security codes ensure total security of operations.
RS 485 Serial Port with galvanically isolated output for data transfer to a remote location.
Optional – TOU for time enabled tariff users and Auto Resetting of Energy Parameters
