Product Overview and 2025 Market Relevance

SiC power system monitoring and diagnostic modules are intelligent add-ons and embedded units that instrument SiC-based rectifiers, inverters, UPS, and DC power shelves to deliver real-time telemetry, predictive maintenance, and remote lifecycle management. Purpose-built for wide-bandgap power trains operating at higher frequency and temperature, these modules capture fast electrical transients, thermal gradients, switching health, and grid quality parameters that silicon-era monitors often miss.

Why this matters in Pakistan in 2025:

• Grid instability and heat: Frequent sags, swells, and harmonics combined with 40–45°C ambients accelerate component aging. Predictive analytics prevent unplanned downtime in textile, cement, and steel facilities and safeguard data center/financial machine room SLAs.
• OPEX and staffing: Automated analytics reduce manual inspections, optimize spares, and shorten MTTR across dispersed telecom and industrial sites.
• Compliance and ESG: Continuous PF/THD reporting, efficiency tracking, and event audits support NTDC Grid Code alignment and sustainability dashboards.

Sicarb Tech provides monitoring modules as:

• Embedded boards in SiC PFC/UPS/DC systems (factory-integrated).
• Retrofit kits for existing power cabinets (DIN-rail or mezzanine).

Key Advantages and Proven Benefits

• Prevent failures before they occur: Detect rising ESR, inductor hotspot drift, or fan degradation weeks in advance to schedule maintenance around production.
• Improve efficiency and power quality: Live PF/THD and switching-loss telemetry guide filter tuning and control updates, enhancing site compliance and lowering OPEX.
• Shorten MTTR and avoid repeat faults: Root-cause analysis correlates grid events with converter responses, cutting troubleshooting time.
• Fit for harsh environments: Coated boards, dust sensors, and positive-pressure logic adapt to cement/textile/steel plant conditions.

• Analytics tuning
• Import site load profiles and grid disturbance records; calibrate ESR baselines post-commissioning; set alert thresholds (warning/critical) per device class.
• Environmental protection
• Apply conformal coating; deploy IP54+ enclosures and positive pressure where dust is severe; schedule filter cleaning alerts.

Common Questions and Expert Answers

• Will monitoring interfere with protection or control loops?
• No. Our modules use isolated, read-only sensing and time-aligned sampling that do not load or alter control signals.
• How accurate is junction temperature estimation?
• With die-prox sensors and calibrated thermal models, ΔTj estimation typically falls within ±5–8 K of IR thermography benchmarks.
• Can we retrofit existing silicon-based cabinets?
• Yes. DIN-rail kits support legacy systems; analytics still add value, with SiC-aware models selectively enabled.
• What connectivity is supported for remote sites?
• Dual Ethernet, RS‑485, and optional LTE/4G with VPN/TLS. Store-and-forward ensures no data loss during backhaul outages.
• What is the typical ROI?
• 9–24 months from avoided downtime, reduced emergency callouts, and optimized cooling—faster for 24/7 UPS and process-critical lines.
