A TO 30A NOISE FILTERS FOR SPACE-CRITICAL MOUNTING LOCATIONS

Not all mains-connected applications are able to do entirely without a noise filter. Particularly when several components – such as power supplies or drivers – in sum cause the permissible limits to be exceeded, ready-approved filter modules make for the ideal plug & play solution. And, we are happy to announce that we have supplemented our portfolio of filter modules with COSEL’s single-phase EA series offering finely-stepped current capacities of 3A, 6A, 10A, 16A, 20A and 30A.

For the EA series’ design, COSEL, a Japanese manufacturer, placed special emphasis on the devices meeting tight space requirements. As a result, volume has been reduced by 50% compared to existing filter series, while weight has been lowered by 40%. Another focus was fast and easy mounting, resulting in the added benefit of exemplary electrical safety characteristics. For, not only is there no fussing about with screws and covers, but these are also prevented from dropping out and getting lost once the filters have been installed. In addition, the conducting parts are protected against undesirable contact. The filters are optionally available with pre-assembled DIN rail adapters as part of the scope of delivery.

The following single-phase classes are available for the three common fields of use: The EAC class, an optimal filter solution for suppressing low-frequency noise (in the 150kHz to 1MHz range) in “classic” industrial applications with standard ground leakage current values; the EAM class, with low leakage currents, which is optimized for use in medical applications; and the EAP class, which suppresses high-frequency pulses that would otherwise reach the devices to be protected from the input side via the power wiring.

EA series filters are tested to meet the following international safety approvals: UL1283, CSA, DIN 60939, VDE0565 Part 3-1 and ENEC. A five-year manufacturer’s guarantee underscores the use of highest-quality components and production techniques, as one would expect from products made in Japan.
