+ | It is also likely that with currents greater than 13 amperes (roughly 3000 Watts), the impulse width might decrease even further. Assuming we have an S-Watt measuring 10.000 Watts (it is certified up to 50 amperes = 11.500 Watts) and it produces 500.000 imp/kWh, we'd have 500.000 impulses every 6 minutes, or (roughly) 100.000 imp/min, or ~1400 imp/s. It is unknown to me how the S-Watt would handle such high impulse frequencies. | ||
