Hioki PW3336 AC/DC 2-Channel Power Meter (1000 V / 65 A)

Overview
The Hioki PW3336 is a bench-top power meter designed for high-accuracy, versatile power measurement in industrial, laboratory, and production-line settings. It supports both AC and DC measurement, direct input, and external sensors, making it an excellent choice for measuring single-phase to three-phase equipment such as motors, inverters, power conditioners, and power supplies. The device is built to international standards, including compliance with IEC 61000-4-7 for harmonic measurement, and delivers stable results even under challenging conditions such as low power factor or no-load testing.

Key Features

• Direct input measurement up to 1000 V (AC/DC) and 65 A per channel.

• External current sensors allow measurement up to 5000 A AC for large currents.

• Wide frequency bandwidth: DC / 0.1 Hz up to 100 kHz.

• Basic accuracy: ±0.15% rdg for active power (for many models) under specified conditions.

• Harmonic measurement built in, up to the 50th order, with IEC 61000-4-7 compliance.

• Two-channel input supports single-phase 2-wire to three-phase 3-wire configurations.

• Multiple output/communication interfaces: RS-232C, LAN; some variants include GP-IB, D/A output.

• Synchronization: up to 8 units can be synchronized for multi-unit / multipoint measurement.

• Level output and waveform output functionality: instantaneous waveforms, power level outputs, etc.

Applications

The PW3336 excels in precision measurement tasks in fields including:

• Motor and inverter development: comparing input vs output power, verifying efficiency.

• Power supply and conversion equipment: measuring performance under DC, low frequency, distorted waveforms.

• Renewable energy systems: power conditioners, photovoltaic inverters where both DC and AC need measured.

• Transformer and no-load/motor idle testing, especially where low power factor makes measurement harder.

• Quality assurance / production line testing for electrical components.

• Lab benchmarking including server power consumption (SPECpower® compatibility).
