| COMBIMETER
True RMS Digital 7 in 1 Meter – Single Phase |
|
 |
DESCRIPTION |
|
The meter incorporates micro-controller system, which samples voltage and current signals and computes Voltage, Frequency ,Current, Active Power, Reactive Power & Apparent Power. Power Factor is computed by power division method. These parameters are displayed on four digit, seven segment, LED display. |
|
| FEATURES | • |
‘SELECT’ push-button on front side to select Voltage, Frequency, Current, Power Factor, Active Power, Reactive Power & Apparent Power. |
| • | One meter replaces seven meters. |
| • | Complex wiring & panel space required are reduced. |
| • | Sign Indication depends
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. |
