3331 - Hioki Power Recorders

Hioki 3331 Overview

The high-performance 3331 is a 3-phase power meter makes system construction easy.
This single-phase/three-wire, three-phase/three-wire 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.
Measures Voltage, Current, Current peak, Active power, Apparent power, Reactive power, Power factor, Phase angle, Frequency, Power integration, Current integration. Three-phase line imbalance can be checked. Single-phase power for two devices can be measured.
Scaling function (PT and CT ratio), Displays a moving average function, D/A output function, GP-IB/RS-232C interface Scaling function (PT and CT ratio), Displays a moving average function, D/A output function.
