Power supplies deliver high power density
TDK-Lambda has announced the EFE Series of embedded front-end power supplies designed to deliver high power density, high efficiency and enhanced reliability.
Power supplies minimise waste heat
The GEN60-40, GEN150-16 and GEN600-4 models achieve 88% efficiency at 200V AC, while the GEN8-300's efficiency is rated at 84%.
MA12 filters incorporate a single-stage LC network, and are an ideal low-cost choice for standard applications.
They provide efficient attenuation of conducted RFI over the frequency range 150kHz to 1MHz.
To meet the needs of more demanding applications, MX12 filters use a two-stage network, and provide attenuation over the frequency range 150kHz to 30MHz.
As MA12 and MX12 filters have identical dimensions and connections, it is a simple matter to replace an MA12 unit with its MX12 equivalent if, in a particular installation, additional filtration proves desirable.
The filters have a low leakage current of less than 1mA at 250V, 60Hz, and provide isolation between terminals and baseplate which is tested to 2,500V.
Their low series resistance - 120mohm maximum for 6A types and 6mohm maximum for 30A types - guarantees minimal voltage drop across the filter.
All products in Lambda's new MA12 and MX12 filter ranges share a common compact housing, measuring just 90 x 40 x 50mm, making them easy to accommodate, even when space is restricted.
As an aid to fast, easy wiring, they feature convenient screw-clamp terminals with captive screws.
Lambda MA12 and MX12 filters can be operated continuously at their full rated current over the temperature range -40 to +60C and, with appropriate derating, they can be used at up to 85C.
Safety standards UL1283 and EN60939 do not cover operation below -25C but, when they are used at higher temperatures, the filters fully meet the requirements of these standards. Request a free brochure from TDK-Lambda UK ...
