Delta Electronics unveil 3-Phase 960W DIN rail power supply
Delta Electronics has enhanced its popular CliQ II DIN Rail Power Supply series with the addition of a new 3-Phase 960W power supply. The model DRP024V960W3BX provides 24V output with a full corrosion resistant aluminium body that can withstand up to 30G Shock test according to IEC 60068-2-27 and operates over a wide temperature range from -25°C to +65°C.
Tackling EMC in medical power supplies requires innovative design
All modern power supplies are of the switched-mode type, as these are smaller and more efficient than the old linear types. Switched-mode supplies, however, generate electromagnetic interference, both conducted and radiated, and require the incorporation of EMI filters.
Making sense of heat recovery
Mechanical ventilation and heat recovery systems are becoming increasingly necessary as we near the Zero Carbon goals for dwellings by 2016. In this ES Design magazine article, Mike Farrer, Technical Director of Stadium Power, highlights the need for the highest possible efficiency power sources to perform over a wide operating window.
Was Edison Right?
A new movement in the US is seeking to bring back DC power distribution at the building level, which can help reduce power losses. Sally Ward-Foxton discovers more in this interesting article from ES Design magazine.
Microsemi introduces new 650V SiC Schottky solution
Microsemi expands its silicon carbide Schottky product family with a new line of 650 volt solutions targeted at high-power industrial applications including solar inverters. Wide bandgap semiconductors such as SiC feature the most advanced material that is being considered by many power electronics and systems designers in their new designs.
Free Technical Forum Covers Power and Power Management
A free Power and Power Management Technical Forum scheduled for October 22 has attracted a top line up of speakers. The topics will be covered in depth including presentations on Power Design Trends, Design Support Tools, Thermal Materials and DC/DC converter specifications.
Industry’s highest power efficiency in the smallest package
Texas Instruments has added three power management modules to its SIMPLE SWITCHER family, including the 10 A LMZ31710, which provides the industry’s highest power efficiency in the smallest package, up to 50-percent smaller than similar solutions. The easy-to-use power modules drive power-dense applications in a variety of markets including industrial, communications infrastructure, medical, and test and measurement.
Mini 600V superjunction power MOSFETs from Toshiba
Toshiba announces that its next-generation superjunction DTMOS-IV power MOSFET technology is available for the first time in small outline, low-profile DFN packaging. The new 600V DTMOS-IV MOSFETs in a DFN package are ideal for high-speed switching in power supplies, lighting ballasts and other applications requiring a space-saving alternative to more conventional D2PAK and DPAK devices.
MEAN WELL announce a new 6W AC-DC medical adaptor
MEAN WELL have announced the GSM06 series 6W medical adaptor to satisfy the lower wattage power supply requirements of the medical application market. Complying with international medical safety regulations (2*MOPP level), these models also possess extremely low leakage current (≦50 μA) and low no load power consumption (<0.3W), which can fulfill the high quality demands of “patient contact” medical applications.
Improved 24mm die phase control thyristor from IXYS
IXYS introduce a new 24mm die pressure contact phase control thyristor, the N0465WN140/N0465WN160. The new improved design offers an average current rating of 465A, compared to 392A of the established design, which represents a 19% increase and the device is available with voltage up to 1600V.
