Supplier's note

  1. Technical Breakthroughs:

    • The Pro Model’s ±1% voltage accuracy (30% better than industry standards) ensures critical equipment operates flawlessly in unstable grid conditions.
    • Expanded -40°C to +85°C temperature tolerance (vs. Base Model’s -20°C to +60°C) enables deployment in extreme environments like Arctic oil rigs or desert power stations.
    • Active cooling in the Pro Model reduces thermal throttling by 40%, extending runtime in continuous-use scenarios.

  2. Optimal Version Selection:

    • Base Model: Ideal for small-scale diesel generators (≤50kW) in moderate climates.
    • Advanced Model: Suitable for industrial gensets (50–200kW) requiring wider voltage input ranges (e.g., mining or marine applications).
    • Pro Model: Recommended for high-power systems (>200kW) in extreme environments (e.g., offshore platforms or data centers) where precision and thermal resilience are critical.

*Pro Model specifications exceed ISO 8528-5:2010 standards for voltage stability and thermal endurance.
