| High-performance 3-phase power meter makes system construction easy |
|
| This model provides high accuracy of ±0.2 % (45 to 66 Hz), and is capable of measuring and integrating power consumption of 3-phase devices such as industrial air conditioners and refrigerators, as well as single phase (single-phase, 3-wire) equipment. It can handle direct current inputs of up to 50 A, and maintains frequency characteristics over a broad bandwidth from 10 Hz to 100 kHz. Also features wave peak measurement and a U3, I3 display function using vector calculation. Compact and lightweight. |
