Edison, N.J. Designed to save time and cost, Schaffner EMC has introduced new EMC/RFI filters that feature quick, universal snap-in brackets for mounting on DIN rails. The FN 2412 filters are suitable for high-end single-phase power supplies, single-phase variable speed motor drives, small- to medium-sized machines and industrial equipment as well as panel building and electrical cabinets.
Available in two versions, the new FN 2412 filter is designed for common single-phase supply networks and offers a maximum continuous operational voltage of 250 Vac, while the FN 2412H version is designed for operation on two phases in a three-phase power network, handling voltages up to 520 Vac. The FN 2412H provides users with an off-the-shelf solution, which eliminates the need to upgrade a traditional single-phase filter to higher voltage capabilities, said the company.
The new FN 2412 filters offer excellent EMI suppression, reducing conducted emissions and improving conducted immunity. The filters also improve system reliability, which prevents production downtime due to malfunctions caused by conducted interference, said the company, and provide exceptional conducted attenuation performance to meet at least Class A limits, even in very noisy applications and under full load conditions. Unlike traditional filters, the FN single-phase models feature filter chokes that do not saturate under full load conditions, according to the company.
The FN 2412 and FN 2412H filters feature industrial-grade terminal blocks, which provide maximum electrical safety and protection from contact with live conductors. They also offer a long-lasting electrical connection with low impedance, and accept thick installation wires. The new filters meet the latest international safety regulations and are approved by UL, CSA and ENEC.
The meantime between failure (MTBF) at 50°C (122°F) and 250 V is 1,200,000 hours for the single-phase filters and 250,000 hours for the two-phase filters. The temperature range for operation and storage is -25°C to 100°C (-13°F to 212°F). The overload capability is 4x the rated current at switch on and 1.5x the rated current for one minute, once per hour. The filters are available in a choice of eight different rated currents from 8 A to 45 A. Click here for more product information.
FN 2410 filters are also available, which use a traditional chassis mounting design, and offer a choice of eight different rated currents from 8 A to 100 A.
Pricing for an FN2412 starts at $50.00 each. Delivery is four to six weeks.
