Products Features

On site programmable PT/CT ratios: It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site via front panel keys by entering into Programming mode.

User selectable CT Secondary 5A/1A The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A using front panel keys.

User selectable PT Secondary The secondary of external Potential Transformer (PT) can be programmed on site from 100VLL to 500VLL using front panel keys.User can set the display in auto scrolling mode or fixed screen mode using front panel keys.

Low back depth: The instrument has very low back depth (behind the panel) of less than 55 mm(Without output option).

Four function keys: Using the four function key, it is possible to go desired parameter screen instantly..

Demand Measurement Measures & Displays Current Demand, kVA Demand, kW Import Demand, kW Export Demand. Any of the parameters can be assigned to optional Limit switch.
