New models of configurable power supplies

Paul Boughton

Lambda is expanding its highly successful NV-Power configurable power supplies family with the addition of two new model ranges.

The new ranges are aimed at medical, broadcast, test and measurement and general-purpose industrial applications that demand compact 1U high power supplies rated from 300-960W.

The NV300 range offers 300W continuous output power from up to four configurable outputs in a compact 184 x 95 x 34 mm package, making it what Lambda claims to be the smallest power supply of its type on the market today.

A patent-pending noise cancelling transformer is used in conjunction with Lambda's patented multi-resonant topology (MRT) to give curve B EMC performance while achieving less than 300 micro-amps leakage current limit for medical applications. Output 1 has a 'power good' signal provided.

The NV700 range is a classic modular design providing 960W continuous output power from up to nine outputs in a small 257mm x 127mm x 40.6mm package. Each module features 'output good' and 'inhibit' signals and low leakage current and curve B EMC are standard.

The configurable design of Lambda's NV-Power series allows a wide range of output voltage and current combinations to be supplied as fully-approved samples on short lead times. No minimum load is required on any output.

Both the NV 300 and NV700 power supplies come with a choice of customer air cooling or low-noise temperature-controlled fans. Low-profile output connectors allow maximum airflow for optimised cooling efficiency.

Input is 90V to 264V AC, 45-63Hz, and Lambda's multiple-efficiency gain (MEG) techniques produce an efficiency of up to 90 per cent, depending upon the configuration. As well as valuable savings in energy consumption, the resulting reduction in waste heat is a critical feature for today's densely-packed electronic systems. 5V 2A and 12V 1A ATX-compatible standby outputs are available as options for both model ranges.

All products in Lambda's innovative NV-Power range are approved to IEC/EN/UL/CSA 60950-1 for general-purpose applications, IEC/EN/UL/CSA 60601-1 for medical applications, and IEC/EN 61010-1 for laboratory and process control applications. In addition, the units are CE marked.
