Productoverzicht en relevantie voor de markt in 2025

Intelligent monitoring and remote diagnostics modules purpose-built for silicon carbide (SiC) rectification systems provide end-to-end visibility, predictive maintenance, and secure remote support for Pakistan’s textile, cement, staal, and emerging industrial sectors. By combining high-speed data acquisition, edge analytics, and OPC UA integration, these modules transform rectifier operations from reactive to predictive, sustaining >98% rectification efficiency, reducing unplanned downtime, and extending service intervals to once every two years.

In 2025, plants in Punjab and Sindh are integrating SiC rectifiers to counter grid volatility, aging infrastructure, and rising energy costs. Intelligent diagnostics modules complement SiC hardware by continuously tracking thermal behavior, switching health, harmonic performance, and cooling conditions. The analytics engine identifies early signs of degradation—such as Rds(on) drift, leakage current rise, capacitor ESR increase, and coolant flow anomalies—enabling planned interventions. Measured outcomes include 10%–15% annual energy savings, 30%–40% cooling footprint reduction, and >50% lower failure rates in high-temperature, high-dust environments. Compliance-ready data streams support IEC 62477-1 safety, IEC 61000 EMC, and IEC 60747 device documentation, while dashboards feed ISO 50001 and ISO 14001 reporting.
