    FAQ

    Q1: Is a 400W constant current LED driver reliable under high load?

    High-quality 400W constant current LED drivers typically employ high-efficiency topologies and comprehensive protection circuits, enabling stable operation under high load conditions. Even when operating near rated power output for extended periods, intelligent temperature control and current limiting ensure system safety.

    Q2: How should I choose the wattage of my LED power supply?

    When selecting the wattage of an LED power supply, first calculate the actual power requirements of all LED lighting fixtures and then reserve a certain power margin. It is generally recommended to reserve 10% to 30% of the power capacity to avoid the power supply operating at full load for extended periods. Appropriate wattage selection not only reduces power supply temperature rise but also improves efficiency and overall system reliability, making it particularly suitable for lighting scenarios requiring continuous illumination for extended periods.
