Learn more about selecting the right power filter...

The DBA4 series filter uses high-quality manganese-zinc ferrite magnetic rings, inductors and capacitors, with excellent interference suppression capabilities and a wide rated current range (10A-30A), which can easily cope with various application requirements from low power consumption to high power consumption (such as consumer appliances and industrial automation equipment). At the same time, its rated voltage reaches 115/250VAC, which perfectly adapts to global voltage standards and can be widely used worldwide without changing filters. In addition, the 50/60Hz operating frequency compatibility ensures that the DBA4 series filter can operate stably in the power grid environment of different regions.

Powerful EMI suppression capability

The DBA4 series filter uses high-quality components and cutting-edge filtering technology, and is tailored for single-phase power supply systems. It can effectively filter out common-mode and differential-mode interference in the range of 150kHz to 30MHz, ensuring that the equipment can still maintain excellent electromagnetic compatibility (EMC) in a complex electromagnetic environment, thereby ensuring the stable operation of the equipment.
