Performance
Smart power monitor
| Item | KM50-E | |
|---|---|---|
| Accuracy | Voltage | ±1.0% FS ±1 digit (at ambient temperature of 23°C, rated input, and rated frequency). However, the accuracy is ±2.0% FS ±1 digit for the Vtr line voltage for three-phase, three wire power and the Vrs line voltage for single-phase, three wire power under the same conditions. |
| Current | ±1.0% FS ±1 digit (at ambient temperature of 23°C, rated input, and rated frequency). However, the accuracy is ±2.0% FS ±1 digit for the phase-S current for three-phase, three wire power and the phase-N current for single-phase, three wire power under the same conditions. |

| Active power Reactive power |
±2.0% FS ±1 digit (at ambient temperature of 23°C, rated input, rated frequency, and a power factor of 1) Reactive power formula: Reactive power = v x i x sin θ “v” is the instantaneous voltage and “i” is the instantaneous current. θ is the phase difference between the voltage and current. |
