Designed for industrial settings, three newly established vacuum pumps each required a busbar filter to mitigate electromagnetic emissions. Crucially, the device also needed to meet very low leakage requirements for entry into the Japanese market. As the vacuum pump was designed to be a free standing, mobile unit, space in the device was limited and therefore engineers would have to design a bespoke, compact filter.
An innovative, interchangeable filtering solution was designed to support both three phase, and three phase and neutral currents to meet each pumps’ requirements and maintain the same space and mounting footprint. This significantly reduced cost due to filter component modularity, improved system interoperability and streamlined machine production.
The internal PCB had also been designed specifically to accept capacitors of multiple sizes to comply with typical leakage requirements, including those for the Japanese market.
The modular design and flexible capacitor solutions reduced the overall cost and lead time for the client. They can now go to market with an efficient and reliable product which complies with relevant emissions standards.
