Nowadays, the application of power filter is more and more extensive, what we can see is that its wide application has greatly promoted the new development of the filter industry. However, many people encountered problems when installing the power filter because they did not realize the importance of correct wiring. Today, I will introduce you to the precautions of the power filter wiring. I hope it can be helpful to everyone!
First of all, it is necessary to avoid too close to the input line and output line of the power filter. The distance must be kept apart, and parallelism should not be used to avoid reducing the efficiency of the filter. The wires at the (power) end and the (load) end of the filter cannot be bundled together, because this will aggravate the electromagnetic coupling between the input and output ends of the filter and weaken the ability to suppress EMI signals.
Also try to avoid using long grounding wires. The length of the wire connecting the output end of the power filter to the inverter or motor should not exceed 30 cm. Secondly, the power supply filter shell must be in good contact with the chassis shell, and the grounding wire must be connected well. Finally, the input and output connecting wires of the power filter should be shielded twisted pair cables, which can effectively eliminate some high-frequency interference signals.
In summary, it is recommended that you must pay attention to these conditions when wiring the power filter, so that the power filter can perform its maximum function
