IEC 61000-4-30 Class AInspector V4 3 Phase Power Quality Analyzer
Inspector V4 is a continuous power-quality and site-condition monitor for industrial facilities, medical systems, data centers, telecom and building infrastructure. It combines dual isolated PQ channels with high-resolution ADCs, wide I/O and protocol support, on-device storage with battery backup, and expansion units for environmental, motor and analog sensors.
Inspector V4 - Power Quality Analyzer and Continuous 3-Phase Monitor
The Inspector V4 is a professional-grade power quality analyzer and continuous 3-phase power monitor designed for industrial facilities data centers medical systems and building infrastructure. As a dual-channel power quality meter it simultaneously monitors two independent electrical systems — ideal for comparing utility supply against UPS output or monitoring two feeders at once.
This is not a field instrument you carry to a site and retrieve a week later. The Inspector V4 is a permanent power quality monitoring system — always-on; always-recording; and always-communicating. It captures every voltage dip-swell-transient and harmonic disturbance per IEC 61000-4-30 Class A. As a continuous electrical data logger. it stores all data across 16GB flash plus 32GB SD (expandable to 256GB) with a 6-hour Li-ion battery ensuring the power quality data logger never misses a single event — not even the ones caused by the outage itself.

Frequently Asked Questions
Everything you need to know about the Inspector V4 — what it does, how it works, and who it's built for.
Most power quality instruments are designed to be carried to a site, used for a week-long campaign, then retrieved. Inspector V4 is permanent infrastructure — installed once, recording 24/7, sending live data to your systems, and alerting your team instantly when something goes wrong. It doesn't need an engineer on-site. It monitors your facility whether anyone is there or not.
Yes. It supports 1P2W, 3P3W Delta, and 3P4W Star configurations. Uniquely, it carries two fully isolated 3-phase channels — each with 5 voltage and 5 current inputs — allowing it to monitor two independent electrical systems simultaneously. Compare utility supply against UPS output, or watch two feeders at once. No other permanently-installed PQ analyzer in its class offers this.
IEC 61000-4-30 Class A is the highest accuracy class for power quality measurement — required for regulatory compliance, contractual PQ reporting, and legal disputes. Inspector V4 is fully Class A certified across all parameters and, critically, maintains that accuracy through power outages via its 6-hour Li-ion battery backup. It records the event that caused the outage, not just the aftermath.
Inspector V4 logs continuously to 16GB internal flash plus an SD card expandable to 256GB — enough for years of full-resolution data without ever needing to be retrieved or redeployed. It pushes data to your platform in real time and keeps recording indefinitely. There is no "end of campaign" — only continuous, uninterrupted site intelligence.
Yes — and this is one of its defining capabilities. Via expansion modules it monitors temperature, humidity, CO₂, TVOC, particulates, and 3-axis vibration (THPAQ), motor health via non-invasive CTs (MMU), up to 8× 4–20mA analog sensors (SIB), and H₂S/SO₂ toxic gas (SMU). A single Inspector V4 installation consolidates what would otherwise require multiple separate devices from multiple vendors.
Yes — natively, with no middleware. Inspector V4 supports 9 industrial protocols built-in: Modbus, BACnet, IEC 61850, DNP3, MQTT, SNMP, HTTP/HTTPS, IEC 62056, and Email. It connects directly to your existing SCADA system, building management platform, or IoT cloud infrastructure — live, continuously, without any third-party gateways or additional hardware.
