Supplier's note

  1. Three Key Breakthroughs:

    • Expanded control signal compatibility (Pro Model’s PWM support) enables advanced pulse modulation for high-precision applications.
    • Enhanced overcurrent protection (Pro Model’s 10A threshold) exceeds industry standards, safeguarding against surges in harsh environments.
    • Wider operating temperature range (-40°C to +105°C) ensures reliability in extreme industrial settings.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial applications (e.g., HVAC systems) requiring basic 0-10V control.
    • Advanced Model: Suitable for mixed-signal systems (e.g., factories using both 4-20mA and 0-10V protocols).
    • Pro Model: Best for heavy-duty machinery (e.g., mining equipment) needing extreme durability and PWM precision.

With the Pro Model’s 10A overcurrent protection, you can safely handle sudden power spikes in mining operations. Pair its wide temperature tolerance with industrial-grade SCRs to ensure uninterrupted performance in sub-zero environments.
