The SMUN waterproof constant voltage power supply SMV-300 is a power supply product with relatively excellent performance. Here is its relevant introduction:


Basic parameters:
  • Output power: The rated power is 300W, which can provide stable power support for some equipment with medium and high power requirements.

  • Output voltage: Usually, there are multiple output voltages to choose from. Commonly seen ones are 12V, 24V, etc., which can meet the voltage requirements of different equipment. Moreover, the voltage precision is relatively high, ensuring the stable operation of equipment.

  • Input voltage range: Generally, the input voltage range is 170VAC - 264VAC, which is suitable for most conventional mains voltage environments and has good versatility and compatibility. The frequency range is usually between 47Hz - 63Hz.

Protection functions:
  • Short circuit protection: When a short circuit fault occurs at the power output end, the short circuit protection mechanism will start quickly. The short circuit protection mode of this power supply is usually hiccup mode. After the short circuit fault is removed, it can automatically resume normal operation, effectively avoiding damage to the power supply and load equipment due to excessive short circuit current.

  • Overload protection: If the load current exceeds a certain proportion (such as 105% - 135%) of the rated output power of the power supply, the overload protection function will be triggered. Also using hiccup mode, the power supply will automatically restart after the load returns to normal, ensuring the safety of the power supply and load equipment.

  • Overvoltage protection: When the output voltage exceeds a certain proportion (such as 135% - 150%) of the rated output power, the overvoltage protection will start to prevent excessive voltage from causing damage to the load equipment.

  • Overtemperature protection: There is a temperature monitoring device inside the power supply. When the temperature of the internal transistor exceeds the set threshold (such as 150°C), the overtemperature protection function starts, cuts off the output, and automatically resumes work after the temperature returns to normal to ensure that the power supply operates within a safe temperature range.

Other characteristics:
  • Waterproof performance: The waterproof level reaches IP67, with good waterproof and dustproof capabilities. It can adapt to harsh usage environments such as outdoors and humidity, such as outdoor lighting projects and landscape lighting. It can effectively resist the intrusion of moisture and dust and ensure the normal operation and service life of the power supply.

  • Volume and weight: Its volume is relatively compact, which is convenient for installation and layout. The weight is moderate and will not cause excessive burden on installation.

  • Cooling method: Usually, natural air convection cooling is adopted without the need for additional cooling devices. It operates quietly and is energy-efficient.

  • Efficiency: The power supply efficiency is relatively high, which can reduce energy loss and operating costs. The efficiency will vary under different output voltages.
