    EMC/EMI滤波器

    坚力电子能提供世界上种类较多的EMC/EMI滤波器和整流器。凭借全面工程支持，坚力的标准化与根据客户定制的解决方案，将帮助客户达到国际合规标准，并提高电气电子设备的免疫力及安全性。

    电能质量产品

    电力的一个主要方面是其质量和稳定性统称为电能质量。应用于设备上的关键功能和系统需要一个高质量的电能来满足，且需要与可靠的合作伙伴（比如坚力电子）一起合作。

    磁性元件

    磁性部件是电力电子工程的重要部分。感应器和变压器通常是优化系统以实现最高能量输出（比如光伏逆变器）和低耗能（比如整厂优化）的关键所在。

    屏蔽设施类滤波器

    坚力的电源滤波器根据客户要求，分别满足IEC939-1、IEC939-2、EN133000、EN133200、UL1283、CSA C22.2No.8、GB/T15287、GB/T15288、VDE0565-3标准。
