Step-down converters reduce power dissipation by 40%
In order to achieve long-term system reliability,system architects can now rapidly comply to International Electrotechnical Commission (IEC) and safety integrated level (SIL) standardswith the MAX17572 and MAX17574 Himalaya synchronous step-down DC/DC converters from Maxim Integrated Products. The company claims that these converters provide a 40% reduction in power dissipation and shrink solution size by 50% compared to other solutions.
Replacing large rolling bearings requires precision and skill
Extremely large rolling bearings that are used in steelmaking equipment pose significant challenges when they need replacing with regard to the tools, team and strategy deployed.However, this task is not insurmountable, as NSK recently demonstrated in the overhaul of a converter at a major Scandinavian steelworks.
Power supply has Industrial and Medical approvals
The introduction of the UI450 Series of single output 450W power supplies from Polytron Devices has been announced by Gresham Power Electronics.The UI450 fits in a 1U enclosure and has dimensions of 127×76.2×40.1mm (5×3×1.58”) for the open frame unit and 148.2×80×40.6mm (5.83x3.15×1.60”) for the enclosed version.
Update in satcom RF packaging suits automatic test systems
AtlanTecRF has launched a new plug-in 6U Loop Test Translator (LTT) for satcom RF testing.The traditional configuration for loop test translators used in off-satellite set up, calibration, alignment and quality monitoring of ground based equipment in satcom terminals is the 19” x 1U rack mount chassis.In other applications, however, such as automatic test systems used in the manufacture of satellite terminals such packaging does not deliver...
Compact and economical storage tower for sheet metal
Introducing a new tower which provides a compact, standardised solution for automated storage and retrieval of pallets and flat material, metal sawing and storage equipment manufacturer, KASTO has called the system KASTOecostore.Advantages of the KASTOecostore system include its low space requirement, high storage density, short material access times and value for money.
Ultra-wide UV video from GEW
A new video has been released by GEW to illustrate how wide-web converters can benefit from GEW’s fully air-cooled NUVA2 UV systems.The NUVA2 lamphead is available in widths of up to 2.50m and boasts particularly fast switch-on and cool-down cycles achieving considerable electricity and time savings.
Full brick converters suitable for distributed power architectures
The lower cost iFB series of 557-600W rated DC/DC converters have been announced by TDK Corporation, which are packaged in the industry standard full-brick form factor.The iFB models offer high useable power and a robust design suitable for the demands of distributed power architectures. Applications include a wide variety of data communications, telecommunications, and test and measurement equipment.
Controller supports LLC-based power supply designs
ON Semiconductor has introduced an advanced synchronous rectifier (SR) controller optimised for LLC resonant converter topologies. The FAN6248 requires minimal additional components, delivers high efficiency, eases thermal management, improves overall system reliability, and simplifies the design of LLC power supplies.The FAN6248 is an ideal solution for modern, high-performance, power supply units (PSU) where high levels of reliability and effic...
MOSFETs enhance power density of high-efficiency converters
Very High-Voltage (VHV) super-junction transistors have been announced by STMicroelectronics with the extra advantage of a fast-recovery diode. The latest MDmesh DK5 power MOSFETs help designers maximise the efficiency of various power-conversion topologies including LLC resonant converters with Zero-Voltage Switching (ZVS).
Highly integrated PMIC delivers 91% efficiency
Subsidiary of Renesas Electronics, Intersil, has introduced a highly integrated programmable power management IC (PMIC) that delivers 91% efficiency at 1.1V output voltage for application processors, GPUs, FPGAs and high-performance system power. The new PMIC’s low RDS(on) MOSFETs and programmable PWM frequency allows designers to use fewer low-profile external components, enabling a 50mm2power-supply that the company claims is 40% smaller ...
