The water-cooled, modular PQE hMFW active filter meets the requirement for a high degree of protection and can be operated at extreme ambient temperatures of up to 50 °C.

Direct water cooling of the power semiconductors in the PPM-W filter modules dissipates the heat at the source. With a rated current of 150 A, the modules have a high power density. The self-closing water plug-in connections make maintenance and expansion of the filters very easy.
