DEM Manufacturing has uprated its MIF range of EMI filters in line with the standard UL 1449 Third Edition, ensuring these components offer high surge and transient protection.

The company said move has made the components compliant with the new standard six months ahead of the deadline.

The focus of UL 1449 Third Edition has been on assuring the safety of products, including filters, which mainly use fixed clamping components such as metal oxide varistors and silicon avalanche diodes as their primary surge-suppression component.

The MIF range, which incorporates surge protection, now utilises only the higher grade ‘PC’ type varistors for permanently connected applications and therefore will deliver high protection from the damaging effects of indirect lightning strikes, surges and transients.

The single-phase MIF and three-phase MIF3 are high-performance EMI filter ranges offering multi-stage filtering, and suitable for applications with a long cable length between the drive and the motor.

MIF has a 250V current rating, is offered with 3-32A current ratings and is footprint mounted.

MIF3 has a voltage rating up to 520V, is offered with 4-400A current ratings and is dual mounted (flat and book-end).

Both ranges are approved to EU UL Fifth Edition, and Canadian standards.
