Multi-output supply adds fan for full
power
The new integral-fan version of the NV-175 compact multi-output power supply can deliver full rated output power continuously at ambient temperatures as high as 50C.
The new integral-fan version of Lambda UK's popular NV-175 compact multi-output power supply can deliver its full rated output power continuously, at ambient temperatures as high as 50C, even when there is no external source of cooling air flow This capability, together with the whisper-quiet operation of the temperature-controlled fan makes the new unit suited to use in medical equipment, test and measurement and other applications where a compact supply is needed, but noise levels must also be minimised

Compact 175W switcher is a cool customer
For a multiple-output, sub-200W AC/DC power supply, the NV-175 packs a punch way beyond its class.
Multiple-output supplies gain military approval
Lambda's compact NV-175 and NV-350 multiple-output power supplies have been granted approval in line with the stringent demands of US military standard MIL-STD-801E.
Designed to operate from inputs in the range from 90 to 264V at 47 to 63Hz, Lambda's versatile NV-175 power supplies are available with up to five outputs, covering the range 0.9 to 28V and delivering currents from 1 to 25A, depending on the output configuration.
To further enhance their versatility, both the fan and fanless versions of models with a 12 or 24V main channel have now been upgraded to deliver 200W peak power, with a maximum average load of 180W in any 5min period.
Use of Lambda's patented multiresonant topology (MRT), which reduces switching losses and the amount of heat generated, enables NV-175 power supplies to achieve an exceptionally high power density of 9.3W/in3.
The overall size of the units is, therefore, just 32 x 76 x 125mm, and they can be housed in a 1U equipment tray.
Weighing in at 230g, they are also 20% lighter than typical supplies with a similar rating.
As the Lambda's MRT circuitry uses soft switching techniques, the level of harmonics generated is inherently low.
This translates to excellent EMC performance, and NV-175 power supplies meet both the Level B requirements of EN55022 for conducted emissions and also the requirements of the demanding EN60601 standard. Request a free brochure from Lambda ...
