Extech PQ3450-30 3000A Datalogging Power Analyzer Kit

The PQ3450‑30 is a robust and feature‑rich instrument tailored for engineers and maintenance professionals working on three‑phase electrical distribution systems. Its rugged build features a large back‑lit dot‑matrix LCD screen, an on‑screen menu interface, and a built‑in clock/calendar for timestamping logged data. It supports true‑RMS measurement of voltage (up to 600 V AC) and current (up to 3,000 A via the supplied flexible clamps) and calculates key parameters such as active, apparent and reactive power, power factor, phase angle and energy consumption.For data capture it supports logging up to 30,000 reading sets onto an SD card in a format ready for Excel® analysis. Users can configure sampling intervals from as fast as 2 seconds up to 2 hours, making it suitable for short‑term trend capture or long‑term energy auditing.It also supports adjustable CT (current transformer) and PT (potential transformer) ratios (CT: 1‑600, PT: 1‑1000) which allow it to integrate into large power systems with external transformer scaling.The kit typically includes three flexible 3000 A current clamps, four voltage leads with alligator clips, SD memory card, power adapter (100‑240 V AC), batteries (AA type) and a protective carrying case — making it ready for field use out of the box.With a safety rating of CAT III‑600 V and typical accuracy specs such as ±0.5% for voltage/current readings and ±1% for active power (plus additional clamp/transformer error) it is suitable for professional power measurement and energy auditing tasks.

Features

• Supports current measurement up to 3,000 A via supplied flexible clamps.

• AC voltage measurement up to 600 V AC (true RMS) for three‑phase systems.

• Logging capacity of up to 30,000 data sets onto a removable SD memory card, in Excel®‑compatible format.

• Sampling interval adjustable from 2 seconds up to 2 hours, enabling flexible data capture durations.
