    Tips: How to select power line filter?

    1. According to equipment rated working voltage, current and frequency, it can confirm filter type. Don’t take too small rated current of filter, otherwise it will damage filter or reduce filter life time. Don’t take too large rated current, because large current will increase filter dimension or reduce filter electrical performance. Normally confirm filter rated current according to 1.2 times of equipment rated current.
    2. According to field interference source of equipment, confirm types of interference noise, common mode interference or differential mode interference, and then select the suitable filter. If interference type can’t be confirmed, thus confirm filter model according to practical exploration, which is a practical and effective method.
    3. Select a filter according to allowable value of maximum leakage current, especially for some medical care equipment.
