Power supplies handle 1450W peaks

Lambda's digitally controlled modules incorporate an integrated magnetics transformer that allows for small size and increased efficiency.

Lambda has added digitally controlled modules to its NV-Power family of configurable AC/DC power supplies enabling increased power output of up to 1450W peak rating for 10 seconds.

The new modules enable Lambda to satisfy the increasing demand for 1U high configurable power solutions above 1000W in broadcast, instrumentation and medical markets and other applications, such as ATE, automation, routers and servers and security networks.

The digitally controlled modules incorporate an integrated magnetics transformer that allows for small size and increased efficiency.

The digital control allows customisation based on the application's requirements (such as modified current limit or start-up characteristics).

Input to output isolation meets the 4kV AC reinforced requirement for medical use.

NV-Power employs an 8bit microcontroller to handle housekeeping routines, replacing the array of comparators, op amps and other discrete components used in less integrated designs.

This brings a 50% parts count reduction which in turn allows 40% more board space for power components.

The NV-350 range offers up to 600W continuous output power (750W peak for 10 seconds) from up to six configurable outputs.

Lambda's multiresonant topology (MRT) and other EMC improving design features give curve B EMC performance with earth leakage current less than 300uA at 264V AC, 63Hz (meeting the requirement for IEC/EN/UL60601-1).

The NV-700 range offers up to 1150W continuous output power (1450W peak for 10 seconds) from up to eight configurable outputs.

The digitally controlled single-output C module is three slots wide and available with 12, 15 and 24V outputs offering 450W continuous and 600W peak power for up to ten seconds.

Each module features output good and inhibit signals with the power supply offering low leakage current and EN55011/55022 curve B EMC as standard.

Using the Lambda NV-Power Configurator, designers can create their own configuration online.

This tool checks the configuration and offers the optimum solution with fully approved samples available on short lead times.

All outputs are fully isolated and no minimum load is required.

Low-profile output connectors allow maximum airflow for optimised cooling efficiency.

Outputs covering the 3.2 to 64V range are available as well as 5V/2A and 12V/1A ATX-compatible standby outputs.

NV-Power employs multiple efficiency gain (MEG) technology to produce a class efficiency of up to 90%, depending upon the configuration.

All products in Lambda's NV-Power range are approved to IEC/EN/UL 60950-1 for general purpose applications as well as IEC/EN/UL 60601-1 for medical applications and IEC/EN 61010-1 for laboratory and process control applications.

In addition, the units carry the CE mark and come with a three-year warranty.
