    FAQ

    Q1: How does the multi-layer protection system benefit my equipment?

    The integrated protection system acts as a comprehensive safety net. It not only regulates voltage but also actively shuts down output or provides alerts in case of dangerous conditions like extreme voltage surges, overloads, or internal overheating, preventing costly damage to your connected machinery.

    Q2: What is the response time for the servo-motor adjustment?

    The servo-motor system provides dynamic correction, typically responding to voltage fluctuations within milliseconds. This rapid adjustment ensures that sensitive equipment receives a consistent voltage supply without interruption or harmful spikes/dips.

    Q3: Can this 20 kVA stabilizer be customized for a specific voltage requirement not listed (e.g., 400V)?

    Yes. A key feature of this industrial-grade stabilizer is its customizability. Please contact our technical support team to discuss specific input or output voltage requirements for your application.
