DIN Rail Power Quality Meter — Titan PQ
Analyser-Class PQ. Permanent Installation.
Class 0.2S energy metering with IEC 61000-4-30 power quality measurement. Harmonics to the 63rd, flicker, transient capture, and ITIC/CBEMA classification — on a compact DIN rail device.
Titan PQ is a DIN-rail power quality meter designed against IEC 61000-4-30 Class S, with Class 0.2S active-energy metering in the same device. It is for industrial plants, data centres, solar plants and hospitals that need permanent PQ monitoring, and it measures harmonics to the 63rd order, flicker, voltage sags and swells, and transients above 50 µs.

Why Titan PQ
Three reasons commissioning engineers, EHV consultants, and tender writers specify Titan PQ for permanent power-quality monitoring instead of an annual analyser audit.
IEC 61000-4-30 Class S
Power quality measurement to the standard that tender writers cite. 10/12-cycle aggregation, IEEE 1588 time sync, IEC 62586-2 PQI-S third-party validation.
Analyser-Class PQ Features on a DIN Rail
Harmonics to 63rd plus inter-harmonics, flicker per IEC 61000-4-15, transient capture above 50 μs with waveform recording, voltage unbalance with sequence components, RVC, and ITIC/CBEMA curve classification — usually only on portable analysers.
Revenue-Grade Energy Metering
Class 0.2S active energy and Class 0.5S reactive energy per IEC 62053 — so the same device delivers the energy bill audit and the power-quality audit. 4-quadrant kWh/kvarh/kVAh, sliding-window demand, up to 8 TOU/TOD tariffs.
The Problem
Industrial facilities with sensitive loads — drives, VFDs, data-centre IT, semiconductor process equipment, hospital imaging — see voltage events, harmonic distortion, and flicker that an energy meter does not capture. Portable PQ analysers visit for a few weeks, measure deeply, then leave. The events that take a line down often happen between visits.
Permanent DIN rail PQ meters from international vendors deliver most metering basics but stop short of analyser features — flicker, transients, ITIC/CBEMA classification, RVC, gapless measurement. Tender writers asking for IEC 61000-4-30 or PQI-S certification are pushed toward ₹3-5 lakh imported devices.
Titan PQ closes that gap — analyser-class measurement on a compact DIN-rail device.
Voltage Sag, Swell, Transient & THD Harmonics Monitoring
Plant managers, data-centre operations and hospital BMS teams don't hunt for “a power quality meter” — they chase symptoms. A drive that trips at random. UPS that goes to battery for no logged reason. A transformer running hot. A chiller compressor that fails six months early. The forensic evidence sits in the voltage sag and swell events, transients, harmonics and THD that a regular energy meter never captured. Titan PQ is the permanent industrial monitor that catches all of them.
On a single DIN rail device:
- →Voltage sag & swell monitor: IEC 61000-4-30 Class S half-cycle RMS detection across all three phases. Sags below 90 %, swells above 110 %, interruptions below 5 %, with ITIC / CBEMA / SEMI F47 classification per event.
- →Transient capture: voltage transients above 50 µs duration captured with pre-trigger waveform — the events that destroy electronics but never show up in an energy log.
- →Industrial THD harmonics analyzer: full harmonic spectrum to the 63rd order plus inter-harmonics, TDD calculation, and harmonic-direction flagging — so blame for distortion at the point of common coupling can actually be settled.
- →Flicker & RVC: IEC 61000-4-15 Pst / Plt flicker plus Rapid Voltage Change tracking — the metrics tender writers ask for and portable analysers usually leave behind.
- →Gapless measurement: continuous recording 24/7, not the 30-second skip every 10 seconds that affordable PQ meters fall back to.
Sites where this matters: data centres tracking IT-load PQ for uptime SLAs, hospitals protecting imaging equipment, paint shops and semiconductor lines where a 2-cycle sag drops a batch, and any facility filing IEEE 519 or EN 50160 compliance reports against a DISCOM dispute. The full spec set is in the Power Quality Features section below.

Applications
Where permanent power-quality monitoring earns its keep.
Industrial Plants & Process Lines
Sensitive drives, VFDs, induction furnaces, and electronics loads see harmonics, sags, and flicker that an energy meter alone misses. Titan PQ provides the diagnostic trail when a sub-station event takes a line down.
Data Centres
Continuous monitoring of harmonic distortion, voltage events, and power factor for IT-load circuits. Waveform-level evidence for SLA, insurance, and uptime audits.
Solar & Hybrid Plants
Inverter-led harmonic injection, anti-islanding events, and grid-side voltage variations measured against the CEA harmonics regulation. Useful evidence for utility / DISCOM disputes.
Hospitals & Critical Infrastructure
Power-quality assurance for life-safety and imaging loads. Sags, swells, and transients captured with waveform context for root-cause analysis.
