The new digitally controlled modules incorporate many innovativedesign features including a new integrated magnetics transformerthat allows for small size and increased efficiency. The digitalcontrol allows customizations based on the application’srequirements (such as modified current-limit or start-upcharacteristics). Additionally, the input to output isolation meetsthe 4kVac reinforced requirements for medical use.

NV-Power employs an 8-bit microcontroller to handle housekeepingroutines, replacing the array of comparators, op amps and otherdiscrete components used in less integrated designs. This brings a50% parts count reduction which in turn allows 40% more board spacefor power components. With the incredibly high peak power ratingdesigners can realize power densities of up to 19W/in3. All unitsoperate with a input range of 90 - 264Vac.

The NV-350 series provides up to 350W of output power with<180Vac mains, and up to 660W continuous (740W peak for 10seconds) with >180Vac mains. Up to six user-selectable outputscan be provided in a 1.6 x 3.75 x 10.8-inch package.

While the NV-700 series provides up to 700W of output power with<150Vac mains, and up to 1150W continuous (1450W peak for 10seconds) with >150Vac mains. Up to eight user-selectable outputscan be provided in a 1.6 x 4.92 x 10.8-inch package.

Lambda’s Multi Resonant Topology (MRT) and other EMCimproving design features have resulted in meeting Curve B EMCperformance with earth leakage current less than 300µA at264Vac, 63Hz (meeting the requirement for IEC/EN/UL60601-1).

Available with an extensive range of output modules and options, itis possible to achieve a wide range of output voltage and currentcombinations. All outputs are fully isolated, no minimum load isrequired and each module features output-good and inhibit controlsignals.
Of particular note, the new digitally controlled single-output‘C’ module is three-slots wide and available with 12V,15V and 24V outputs offering as much as 400W continuous and up to600W peak output power for up to ten seconds.

Using the Lambda NV-Power Configurator, designers can create theirown configuration online. This tool checks your configuration andoffers the optimum solution with fully approved samples availablewith short lead times.

Cooling is by the choice of either customer-provided-forced-air orvia a low noise temperature controlled fan. Outputs covering the3.2V to 64V range are available as well as 5V/2A and 12V/1A‘ATX-compatible’ standby outputs. The NV-Power employsMultiple Efficiency Gain (MEG) technology to produce a classleading efficiency of up to 90% depending upon the configuration.

All supplies in Lambda’s NV-Power range meet EN55011/55022Curve B EMC, are EN61000-3-2 compliant (PFC) and are approved toIEC/EN/UL60950-1 for general purpose applications as well asIEC/EN/UL60601-1 for medical applications and IEC/EN61010-1 forlaboratory and process control applications. In addition, the unitscarry the CE Mark, are fully RoHS-compliant and come with athree-year warranty.

The NV-Power series are available now with prices starting at $214each in 100 piece quantities depending upon the configuration. Moreinformation about Lambda’s NV series is available at:http://www.lambdapower.com/products/nv-series.htm .
