MOFI HiFi AC Power Line Single EMI Filter Module 660W Version DIY KIT & Board
DIY KIT Project
To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required.
Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve problems by yourself.
We do not provide information other than the product introduction page.
MOFI HiFi AC Power Line Single EMI Filter Module 660W Version DIY KIT
This product is used for AC 100-240V filtering.
Have anti-voltage surge function.
Capable of eliminating the DC offset of the mains power.
The 4th-order low-pass filter can effectively suppress and eliminate the high frequency noise mixed from the power grid.
neat design and easy to place.
he components on the board will generate high voltage through the mains power. Please be careful not to touch the circuit board and its components to avoid electric shock.
Application:
Please reserve 30% redundant power for the board.
When your mains power is 220V AC, the maximum support power is 660VA, it is recommended that the load power of transformer less than 460W.
When your mains power is 110V AC, the maximum support power is 330VA, it is recommended that the load power of transformer less than 230W.
Product configuration
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .
Finished board: Based on the well-tested board on the standard version kit, we verified all key points' voltage, and used the signal generator and oscilloscope for analog waveform double verification. We will not use this board for listening test.
All finished pcbs are all carefully hand-soldered and fully tests, so the price is higher and less cost performance. Price-sensitive consumers but with have DIY ability are recommended to choose the kit.
DIY KIT Instructions
Since the PCB holes are plated through, you only need to solder the parts from the bottom of the board. Do not drill or enlarge the holes because that would damage the through-plating.
Clean both sides of the blank PCB with paper towel and isopropyl alcohol or electronics flux remover, then solder the components to the board, starting with the lowest profile parts.
Make sure the correct part goes into each position on the circuit board.
Pay attention to the polarity of electrolytic capacitors, diodes, , as well as the orientation.
Clean up the solder flux residue from the board with isopropyl alcohol (or electronics flux remover) and a brush.
Inspect all solder connections carefully, using a magnifying glass, to make sure there are no solder bridges or cold solder joints. Use a multimeter in ohms scale to check for short circuits.
