XP Power today announced the launch of the highly efficient single output AFM series of 48 & 60 Watt external AC-DC power supplies designed for a wide range of IT and medical equipment. The ranges offer output voltages of 12, 15, 18 and 24 VDC. Offering a typical efficiency of up to 88%, these highly efficient units meet the latest stringent energy efficiency standards such as Energy Star Level V, EISA2007 and CEC2008 in the United States and the ErP Directive for Europe. These standards define the average energy efficiency and the maximum no load power consumption. The AFM45 has a no load power consumption of less than 0.3 W, and the AFM60 less than 0.5 W.
In addition, the AFM series comply with the internationally recognized safety approval standards for IT and commercial equipment IEC60950-1 / UL60950-1 / EN60950-1. They also comply with the IEC60601-1 / UL60601-1 / EN60601-1 medical safety standards.
The units offer multiple input cable interface options allowing designers to specify either IEC320-C14, -C6 or -C8 connectors. The -C8 option provides a Class II grounding method. An optional cable restraining clip is also available.

XP Power is an Energy Star partner and has an approved certification facility that allows in-house testing for compliance to the energy efficiency standards.
To help designers keep up to date with the changing energy efficiency legislation, XP Power provides a number of useful resources and information on their web site. This can be found here: http://www.xppower.com/page.php?pagename=Energy&lang=EN
In addition, XP Power applications and support staff can assist customers in understanding the various “green” initiatives. To make contact with your local XP Power office or representative use the list of locations provided here: http://www.xppower.com/page.php?pagename=Offices&lang=EN
Applications support is also available via a live chat facility.
The AFM series is available from Newark or direct from XP Power.

The 5MPA series ac film capacitors handle from normal line frequency currents to 83.2 A_RMS from 2 kHz to resonant frequency. They offer a high voltage rating of 530 V ac and a dissipation factor of 0.1%. Flat copper terminations enable wide frequency response and low electrical and thermal impedance. Capacitors with values up to 10 µF come with brass bolt terminations. Devices at values up to 100 µF come with a “bridge and bolt” design. Operating up to 85°C, the capacitors perform over the current-handling spectrum from 50 Hz to 20 kHz superimposed feedback. Units are wrapped with flame-retardant insulating sleeves and end-filled with a flame-retardant potting compound. Optional molded mounting brackets are available for higher-value capacitors. Available now, the 5MPA capacitors cost between $6 and $30 each, depending on power requirements and quantity ordered.

Now available from Farnell stock, The Texas Instruments (TI) ADS5400 is a 12-bit, 1GSPS analogue-to-digital converter (ADC) that operates from both a 5V supply and 3.3V supply, while providing LVDS-compatible digital outputs.

The analogue input buffer isolates the internal switching of the track and hold from disturbing the signal source. The simple 3-stage pipeline provides extremely low latency for time critical applications. Designed for the conversion of signals up to 2GHz of input frequency at 1GSPS, the ADS5400 has outstanding low noise performance and spurious-free dynamic range over a large input frequency range.

The ADS5400 is available in a TQFP-100 PowerPAD package. The combination of the PowerPAD package and moderate power consumption of the ADS5400 allows for operation without an external heatsink. The ADS5400 is specified over the full industrial temperature range (-40C to 85C), says the company.

The new CSS65 series of compact, single-output power supplies, designed specifically for medical applications, has been introduced by TDK-Lambda EMEA.

With 4kVAC reinforced input to output isolation and input to ground isolation of 1500VAC, all CSS65 models meet the applicable safety requirements of UL/EN/IEC60601-1 making them suitable for use in medical devices with applied part rating B.

Offered in an industry standard 2 x 4 inch footprint, with a low-profile of 30mm including underside components, the open-frame CSS65 power supplies come with dual fused universal ac input, and can deliver up to 65W at 50C under convection cooling. Worst-case leakage current is less than 250.
