DISCONTINUED ITEM
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.

  • High basic accuracy of ±0.2%
  • Responsitivity that follows transient power fluctuations
  • Simultaneous integration of current and power at a 6-digit high-resolution state
  • Broadband feature compatible with frequency control devices
  • 50A direct input
  • Measuring the effective value of basic wave components only
  • Current waveform peak measurement function
Measurement Lines Single-phase 3-wires, Three-phase 3-wires, Single-phase 2-wires
(no independent settings for each line)
