Over Under Voltage protection Over Voltage Protector

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Protection: Safeguards electrical equipment against overvoltage (up to 260V), undervoltage, and short circuits, ensuring stable power supply.
  • Real-Time Monitoring: Equipped with LED indicators for instant feedback on protection status (overvoltage, undervoltage, and operational readiness via "Green Running" mode).

Key features

  • 1. Material Technology

    • With copper conductors and a durable plastic housing, ensure efficient power flow and long-lasting durability. The corrosion-resistant design safeguards against environmental wear, ideal for industrial or commercial settings.

  • 2. Interactive Design

    • With LED status indicators, monitor protection modes (overvoltage, undervoltage, green running) in real-time for proactive adjustments. The intuitive interface simplifies troubleshooting compared to models with non-visual feedback systems*.

  • 3. Performance Parameters

    • With a wide input voltage range (100V-260V) and 20kVA output power, handle extreme voltage fluctuations and heavy loads ~30% more effectively than standard models*. The 0.2-0.3s recovery time ensures minimal downtime during power instability.

  • 4. Scenario Solutions

    • With DIN rail mounting and customizable voltage thresholds, adapt to diverse industrial or commercial environments seamlessly. Unlike fixed-configuration protectors, this device supports tailored protection for machinery, servers, or appliances*.

  • 5. Certification Standards

    • With CE certification and triple protection (overvoltage, undervoltage, short-circuit), meet stringent safety standards for reliable operation. Exceeds basic surge protectors by addressing undervoltage and short-circuit risks simultaneously*.

Supplier's note

  1. Technical Breakthroughs:

    • Triple Protection: Combines over/undervoltage and short-circuit safeguards to prevent cascading failures in unstable grids.
    • CE-Certified Reliability: Meets EU safety standards for commercial and industrial use.
    • LED Feedback: Real-time status alerts reduce downtime through proactive maintenance.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential or small businesses needing 20kVA protection (e.g., home appliances, office servers).
    • Advanced Model: Suitable for medium-scale industries (e.g., manufacturing lines) requiring expanded voltage tolerance and faster response times.
    • Pro Model: Designed for heavy-duty applications like data centers or mining equipment, offering 40kVA output and 87.5% higher short-circuit capacity than the base model.

With copper components, you can achieve 20% better heat dissipation than aluminum-based models. The Pro version’s 0.1s recovery time ensures minimal disruption in critical infrastructure systems.
