UTE323 3-Ch High-Precision Digital Power Meter
$3,699.00
Sale price $3,699.00Regular price
Overview
The UNI-T UTE323 Series is a three-channel high-precision digital power meter for three-phase and multi-rail power measurement. Three synchronized measurement channels capture a full three-phase system — or three independent DC/AC rails — in one instrument, with per-channel and total power, power factor, frequency, energy and harmonics.
It samples at 300 kSa/s across a DC to 300 kHz bandwidth and supports every standard wiring configuration (1P2W / 1P3W / 3P3W / 3P4W / 3V3A). The UTE323 communicates over RS-232; the UTE323G substitutes GPIB for instrument-bus racks. Measurement firmware and accuracy are identical.
Choosing Your Model — UTE323 Series
Two models, one platform. They differ only by communication interface — channel count, accuracy, 300 kSa/s sampling, wiring modes and harmonic analysis are identical:

Need single-phase high-voltage measurement, or a compact panel meter? See the single-channel UTE310 Series (600 V / 1000 V single-phase) or the UTE9800+ Series compact power meters — distinct instrument lines for different measurement needs.

Three-Phase & Multi-Rail Wiring Modes
The UTE323 supports every standard configuration — single-phase two/three-wire, three-phase three/four-wire and the 3V3A method. One instrument measures a complete three-phase inverter output, a three-rail DC bus or three independent converters without re-cabling between standards.
×UTE323 multi-parameter measurement display
Synchronous 300 kSa/s Multi-Channel Sampling
All three channels sample synchronously at 300 kSa/s, so phase relationships and per-phase power are measured against a common time base — essential for true three-phase power and imbalance measurement.

×300 kSa/s synchronous sampling on all channels
DC to 300 kHz wide-bandwidth measurement
DC to 300 kHz Wide-Bandwidth Measurement
The wide DC–300 kHz bandwidth keeps switching content and harmonics in the per-phase power calculation, so three-phase inverter and drive measurements reflect the real waveform rather than the fundamental alone.

Per-Channel Harmonic Analysis
Harmonic analysis to the 50th order runs on each channel independently, quantifying per-phase distortion on three-phase rectifier and drive front ends.

Per-Channel Energy Integration
Watt-hour and amp-hour integration accumulate per channel for three-phase efficiency runs and long-duration multi-rail energy profiling.

Simultaneous Waveform Display
The 5-inch display shows all channel waveforms together, confirming phase rotation and wiring before the measurement is trusted.

D/A analog output for external recording
D/A Output
A D/A analog output drives a chart recorder or DAQ for long-term trend logging of any measured channel.

GPIB in Place of RS-232 — UTE323G
The UTE323G substitutes a GPIB (IEEE-488) port for RS-232 — it does not add GPIB alongside it. USB and LAN are present on both models, so if you automate over LAN the base UTE323 already covers you; the UTE323G is for racks built on a GPIB instrument bus.
Applications
Three-Phase Inverter & Motor-Drive Efficiency
Measure three-phase output power and per-phase imbalance on inverter and motor-drive designs in a single instrument, with synchronous sampling that holds phase relationships true.
Multi-Rail & Multi-Converter Test
Three independent channels measure three DC/AC rails or three converters at once — one instrument instead of three single-channel meters on a multi-output power-electronics bench.
Production & QA Test Bench
Per-channel limits, energy integration and a single RS-232/GPIB or LAN connection make the UTE323 a compact end-of-line and QA power-test station for small test labs and consultancies.
Accessories and Family Options
UTE-series test cables support safe three-phase connection. Pair the UTE323 with UNI-T programmable sources and electronic loads for a complete three-phase power-characterization bench.
Frequently Asked Questions
Can the UTE323 measure a full three-phase system at once?
Yes. Three synchronized channels and the 3P3W / 3P4W / 3V3A wiring modes measure a complete three-phase system in one instrument.
Can the three channels measure independent rails instead of one three-phase system?
Yes. The three channels can measure three independent DC/AC rails or converters simultaneously.
Does the UTE323G add GPIB on top of RS-232?
No — it substitutes GPIB for RS-232. USB and LAN are on both models; the UTE323G is for GPIB-bus racks.
Does each channel measure harmonics?
Yes — per-channel harmonic analysis to the 50th order.
