FAQ:

Does AC-DC Power Board support the use of high-power devices?

The power capacity of AC-DC Power Board is limited and is generally suitable for small to medium-sized electronic devices. If you need to provide power for high-power devices, you need to choose an AC-DC power board with a higher rated power. High-power applications require the use of specially designed high-efficiency power boards that can handle larger current loads while ensuring the stability of the output voltage.

What is the power conversion efficiency of AC-DC Power Board?

The power conversion efficiency of AC-DC Power Board is usually high, generally reaching more than 80%. The specific efficiency is affected by factors such as input voltage, output current and the quality of internal components. High efficiency means less power waste and lower heat generation, thereby improving the stability and safety of the device.

Will the use of AC-DC Power Board generate electromagnetic interference?

AC-DC Power Board may generate certain electromagnetic interference (EMI) during operation, especially in high-frequency switching power supplies. In order to reduce this interference, many power boards use EMI suppression technology, such as shielding, filtering and electromagnetic compatibility (EMC) design. Choosing an EMC-certified AC-DC Power Board can effectively reduce the impact of interference on surrounding electronic devices.

Can the output voltage of the AC-DC Power Board be adjusted?

For some high-end or special models, the output voltage can be adjusted by adjusting the potentiometer or digital interface. This adjustable voltage function is particularly suitable for occasions where voltage requirements need to be switched between multiple devices. For example, in laboratories, R&D environments, or some industrial applications that require precise voltage control, using an AC-DC Power Board with adjustable voltage can provide greater flexibility and adaptability. However, users need to follow the regulations in the product manual when adjusting the voltage to ensure that the adjustment range does not exceed the maximum output capacity of the power board, otherwise it may cause power damage or unstable output.
