| COMBIMETER True RMS Digital 7 in 1 Meter Three Phase |
![]() |
| DESCRIPTION |
|
The meter incorporates micro-controller system, which samples voltage and current signals and computes Voltage, Frequency, Current, Active Power and Reactive Power & Apparent Power. Power Factor is computed by power division method. These parameters are displayed on Four Digit, Seven Segment, LED display. With MODE push button respective phases (L1, L2, L3) & System (Σ) are selected. A single 7 in 1 meter can replace 11 meters viz. 3 Ammeters, 3 Voltmeters, 1 Frequency meter & 1 Three phase meters each of kW, kVar, kVA & PF. Thus saving cost & immense panel space. |
| FEATURES | • |
SELECT push-button on front side to select various parameters i.e. Voltage (phase to neutral / phase to phase), Frequency, Current, Power Factor, Active Power, Reactive Power & Apparent Power. |
| • | MODE push-button on front side to select indication on respective phases i.e. L1, L2, L3 and Summation Σ. |
| • | One meter replaces minimum of eleven meters on panel. |
| • | Complex wiring & panel space required are reduced. |
| • | 0.000 indication when auxiliary supply is on. |
| • | PFEr indication when input current is not applied. |
| • | ErLo indication when input signal voltage is not applied. |
| • |
Frequency indication on Σ mode when any one
of phase voltage signal is absent. Sign Indication depend upon current direction, sign / no sign indication for EXPORT / IMPORT respectively for Active / Reactive Power. sign / no sign indication for LAG / LEAD respectively for Power Factor. |
| • | Auto scrolling by pressing MODE & SELECT push buttons simultaneously. |
