Logging Capability |
Automatic logging: Measurement items "Hourly" Integrated power consumption and pulse integrated amount for each hour. "Daily" Total amount of power and pulse amount for each day. "Monthly" Total amount of electricity and pulse amount for each month. Collection The latest 65 days' data by hour, the latest 1 year's data by day, and the latest 3 years' data by month are saved in the internal memory. These can be displayed in the display configuration unit. Of the data saved in the internal memory of an SDHC/SD memory card, you can retrieve this month's and last month's data. Detailed logging: Measurement items: Instantaneous power, integrated energy, voltage, current, pulse integrated amount, collected every minute. The latest 1 day's worth (24 hours) is saved in the main unit's internal memory. It can be removed using an SDHC/SD memory card. |
Accuracy |
When using 50 to 600 ACT (model number suffix KN): Instantaneous power (kW) accuracy ±1.0% (relative to rated input)/integrated energy (kWh) accuracy ±1.0% (3.3 to 100% range of rated current, power factor) 1)/Voltage (V) accuracy ±1.0% (relative to rated input)/Current (A) accuracy ±1.0% (relative to rated input)/Power factor (%) accuracy ±3.0% (relative to rated input) ), /5A CT, 5A CT, when using CT for Cantouch bar with built-in Cantouch breaker CT: Instantaneous power (kW) accuracy ±2.0% (relative to rated input): Integrated power consumption (kWh) accuracy ±2.0% ( Range of 5.0 to 100% of rated current, power factor 1)/voltage (V) accuracy ±1.0% (relative to rated input)/current (A) accuracy ±1.0% (relative to rated input)/power factor (%) ) Accuracy ±3.0% (for rated input) |
