In today’s fast-evolving industrial and commercial landscape, energy efficiency is no longer just a cost-saving measure — it is a strategic imperative. From manufacturing plants and data centers to commercial buildings and renewable energy installations, the ability to monitor, analyze, and act upon real-time energy data has become essential for staying competitive. Yet many organizations still struggle with fragmented monitoring systems, limited data visibility, and complex integration challenges.
Enter the Roc-PQP Smart IoT Power Quality Analyzer — a compact, panel‑mount three‑phase power quality analyzer that combines high‑accuracy measurement, massive onboard storage, and versatile connectivity in a single space‑saving package.

Built for Demanding Environments
The Roc-PQP is purpose‑built for modern energy monitoring and power quality analysis. It supports multiple wiring configurations, including 3P4W, 3P3W, 1P3W, and 1P2W, making it suitable for diverse global installations. With external Rogowski coils or voltage‑output current transformers, the Roc-PQP enables non‑invasive testing, dramatically simplifying setup and reducing construction costs — whether you are monitoring secondary sides in medium‑ or high‑voltage substations or directly wiring into low‑voltage distribution panels.
Three Core Advantages That Set It Apart
1. Powerful Data Recording with Local Storage
One of the most distinguishing features of the Roc-PQP is its built‑in 32GB storage capacity. While many meters rely entirely on continuous cloud connectivity to retain historical data, the Roc-PQP empowers users with onboard logging capabilities. It supports programmable interval recording (data logger) and waveform capture, allowing engineers to analyze load profiles, detect power quality issues, and troubleshoot anomalies without the risk of data gaps. This is especially valuable in environments where network connectivity may be intermittent or where long‑term historical analysis is required.


2. Exceptional Flexibility and Expandability
The Roc-PQP fully supports Rogowski coils and voltage‑output current transformers, enabling non‑invasive, clamp‑on testing. This not only simplifies installation but also ensures operational continuity. The meter also accepts voltage inputs via external voltage transformers, adapting seamlessly from low‑voltage to high‑voltage measurement scenarios.
3. Comprehensive Communication Integration
On the communication front, the Roc-PQP is future‑ready. It includes both RJ45 Ethernet and RS485 ports as standard, supporting Modbus‑TCP and Modbus‑RTU protocols. This dual‑communication capability ensures seamless integration with SCADA systems, building management platforms, PLCs, and cloud‑based energy management software, making it a versatile component for new installations or retrofit projects.
