Hioki PW3337 3-Channel Power Meter

Overview

The Hioki PW3337 is a high-precision 3-channel power analyzer designed for measuring DC and AC power across single-phase 2-wire to three-phase 4-wire configurations. It is widely used for development and production testing of motors, inverters, power conditioners, and power supplies, offering accurate measurements even in challenging low power factor conditions.

Key Features

• 3-channel input for DC, single-phase 2-wire, and three-phase 4-wire measurements
• High-precision basic accuracy of ±0.1%
• Wide frequency bandwidth from 0.1 Hz to 100 kHz (or DC)
• Direct current measurement up to 65 A with optional external sensor support for up to 5000 A AC
• Harmonic analysis up to the 50th order per IEC 61000-4-7
• High-accuracy measurement at low power factors, ideal for no-load transformer and motor testing
• Synchronization capability for up to 8 units for multi-unit measurement

Applications

• Motor and inverter development and testing
• Power supply and power conditioner evaluation
• Industrial equipment power analysis
• Transformer and motor no-load testing
• Multi-unit synchronized power measurement
