Power supply certified for medical and ITE use

TDK has introduced the CUS350M series of AC/DC power supplies. Rated at 350W output power, the units have both medical and ITE certification to the IEC 60601-1 and IEC 60950-1 regulatory standards. Requiring no forced air for cooling, the CUS350M is suited for applications where audible noise cannot be tolerated, including hospital, dental, broadcast and professional audio equipment.

DC/DC buck converter has variable output

Rohm has announced a 12 to 76V input DC/DC buck converter with an integrated 76V MOSFET. According to the company, the part, which has an adjustable output, is optimised for high power applications in factory automation, communications infrastructure and industrial machinery.

‘Ultra efficient’ AC/DC power supplies

XP Power has launched the CHD250 AC/DC power supply series. Said to be ultra efficient, the 250W convection cooled single output units are targeted at applications that require medium power in an open frame, fan-less design.

MOSFETs able to balance supercapacitors in industrial applications

Advanced Linear Devices (ALD) has unveiled a family of Supercapacitor Auto Balancing (SAB) MOSFETs which have been designed for industrial applications to regulate and balance leakage currents while at the same time reducing the amount of energy used for balancing supercapacitor cells stacked in series stack of two or more.

SnapUI brings Linux development to embedded systems

ByteSnap Design has launched its Linux OpenGL SnapUI user interface framework. The new design, rewritten from the ground up, is focused on supporting the iMX6 processor to leverage graphical performance, while at the same time retaining core features.

CUI unveils Level VI AC-DC power supply

CUI has unveiled a new line of wall plug-in ac-dc power supplies for the US, Japanese and European markets. The SWI6, SWI12, SWI18 and SWI24 with either North American or European input blades have been designed to meet the stringent new average efficiency and no load power requirements mandated by the US Department of Energy (DOE) which are set to go into effect in February, 2016.
