Targeted for use within applications such as secure communications systems, computer installations and portable screened enclosures, MPE has manufactured low-leakage filters for many years. These filters are designed for use on mains supplies which have a dedicated neutral line and typical leakage current values between 15-100mA. In more recent times MPE has developed and released a range of ultra-low-leakage powerline filters having no neutral line, designed specifically for naval 'floating earth' applications.
During late 2016 MPE updated and expanded this range in response to market demand.
MPE’s ultra-low-leakage filter range now include models from 10-230A, providing high levels of attenuation from 100kHz right up to 18GHz – and with low line-to-earth leakage properties from 6-8mA.
These low-leakage properties allow up to five filters to be deployed in parallel, whilst still maintaining a total leakage current below 30mA. The filters also include high values of discharge resistance, to ensure compatibility with shipborne DC leakage detection systems.
Incorporating the same field-proven, ultra-high-reliability components as utilised for many years in MPE’s other powerline filter ranges, these ultra-low-leakage filters have already been supplied and integrated onto numerous marine platforms.
