KW8M 1 A / 5 A CT input type You can measure with a direct connection to an already-installed large-capacity general-purpose CT. Other Eco-POWER METER Series KW8M 1 A / 5 A CT input type When taking dedicated CT measurements of more than 600 A When taking large-capacity general-purpose CT measurements of more than 600 A Breaker Breaker Power source K Secondary side current Power source Short circuit or less than 0.1 Ω resistance CT (Secondary side current: 5 A) K Secondary side current AKW4801C CT (Secondary side current: 1 A / 5 A) L L L Production equipment K K CT is not required. L AKW8115 Production equipment AKW8111 Eco-POWER METER Series accuracy does not include CT error. For dedicated CT measurements of more than 600 A, two CTs are necessary, but since the 1 A / 5 A CT input type KW8M, direct input from a single CT is possible, and you can carry out measurement with higher accuracy than provided by other Eco-POWER METER Series models. For measurements of less than 600 A, measurement from a single CT, whether dedicated or general-purpose, is possible. Inverter (primary side) measurement function For measurement of inverter power supply equipment introduced for saving energy Owing to general susceptibility to high frequency interference, it is said to be difficult to accurately measure power supplied by inverters.

Consequently, a minimum measurable pulse unit output setting of 40 pulses or less per 1 second is recommended. How to calculate Unit for pulse output: PL-P > Max. measurement power (kW) / 3,600 sec × 4 pulse/sec When the pulse output unit is 0.001, the maximum power that can be properly measured by pulse output is 144 kW (3600 sec × 40 pulse/sec × 0.001). Cautions: (1) Count errors may occur if the pulse output is set to 40 pulses or more per 1 second. (2) If the pulse output OFF time is set too short, count errors by connected counters, PLCs (Programmable Logic Controllers) may occur. 3) These count output specifications are only for the main unit. Note: Digital conversion value differs according to the scaling conversion value set by setting mode. If the analog input value exceeds the upper or lower limit, the digital value will preserve the upper or lower limit.
