Must-Read Before Purchasing:
Regarding Fan Noise:
This power supply is a high-power, 350W industrial-grade switching power supply. To ensure stable operation under heavy loads, it is equipped with a built-in high-speed, high-performance cooling fan.
- A noticeable fan noise is present as soon as the unit is turned on; this is not a silent model.
- If you are extremely sensitive to noise or plan to use this product in quiet environments such as bedrooms or offices, please do not place an order.
- Suitable for industrial settings such as factory workshops, automated equipment, and industrial control cabinets.
❓ Why is the operating noise of this power supply relatively loud?
This product outputs 24V at 350W, making it a high-density, high-power heat source. To ensure electrical safety and extend the power supply's service life, a high-airflow fan is required for rapid heat dissipation. Safe heat dissipation and complete silence cannot be achieved simultaneously.
- Recommendation: If you require a zero-noise solution, you may choose other fanless, naturally cooled power supplies from our store (which typically have lower power ratings), or contact customer service to inquire about alternative models.
