Choosing a proper wall-mount power adapter means a lot to a medical device; a good quality wall-mount power supply will undoubtedly determine the service lifespan, performance, release, and safety and stability of a device. In this blog,I will show you how to select a proper and durable wall-mount power supply.
Confirm Output Specifications
To choose a great adapter, the first way is to check the output specifications. You may figure out the input/output voltage, current, and polarity the device needs.
The voltage must be the same as the device’s requirement; a higher or lower voltage will lead to damage to the device.
As for the current, the adapter you choose must be equal to or higher than the device’s needs; a low current will let your equipment overload and generate heat.
Then you may notice the DC plug, its polarity is divided into positive and negative. If there is a mistake with the polarity when using the supply, the motherboard and the entire electronic system can be directly damaged (burned out).
Check Power Margin and Efficiency
If output voltage and current are the fundamental data for an equipment, power margin and efficiency are those to help devices have a higher maximum performance.
The rated power of the adapter should be 20~30% higher than the device requirement, and a DOE Level VI power supply means higher efficiency and lower operating temperature.
Safety Standards and Certification
Safety standards and certification are issues we often talk about. Just remember choosing IEC60601-1 and 2×MOPP for medical power supply and equipment. Different countries have different standards: UL / CE / UKCA / PSE / CCC / KC / SAA , choose the standard where you sell your equipment.
Build Quality and Materials
From internal structure to outside casing, there is so much for you to notice. Firstly， pay attention to the SMD process, neat solder joints, and transformer potting quality. Then, choose PC flame-retardant plastic instead of low-quality ABS housing.
What’s more, the DC cable should be flexible, bend-resistant, and with sufficient wire gauge, while the connector should be accurate in size, such as 5.5×2.5mm,5.5×2.1mm. After all, good products don’t use inferior materials.
Conclusion — Don’t Treat the Adapter as an Accessory
Just as we mentioned before, a good quality wall-mount power supply will undoubtedly determine the service lifespan, performance, release, and safety and stability of a device.
