30 - 400W Chassis - type Switching Power Supplies without PFC (with an independent housing for easy installation) have a relatively wide power coverage and a relatively sturdy structure, but lack power factor correction. Their application scenarios are concentrated in fields that are cost - sensitive, have lenient energy efficiency standards, and require a certain degree of protection. 

      ●Industrial auxiliary equipment: Such as control power supplies for small conveyor belts, local lighting systems in workshops, power supply modules for non-precision testing instruments, etc. The casing can provide basic dust and moisture protection, and the scenarios where they are used have a high tolerance for power grid harmonics.

      ●Commercial low-cost equipment: Power supplies inside small commercial refrigerators, vending machines, and simple security monitoring host units, etc. These need to be fixedly installed and have requirements for physical protection of the power supply, but do not need to comply with strict energy efficiency regulations.

      ●Regionally characteristic electromechanical products: Small water pumps in some regions, household dehumidifiers (non-energy-saving models), etc. The casing design meets the equipment integration requirements, and there are no mandatory requirements for power factor locally.

      ●Temporary or outdoor equipment: Power supplies for mobile stage lighting, outdoor temporary power supply boxes (for short-term use), etc. The casing can improve durability, and short-term use has limited impact on the power grid.

It should be noted that their application is limited in regions with strict energy efficiency regulations (such as the EU and North America), and they are not suitable for sharing the power grid with precision electronic equipment to avoid abnormalities caused by harmonic interference.
