SL Power Electronics has introduced its smallest commercial 200W power supply with a power density of from 10 to13W/cubic inches.

According to Nigel Davies, SL Power’s European managing director: “Three years ago, it was only just possible to achieve around 100W from a 127x76x30mm (5x3x1.16in) form factor. The new GNT200 series can give 240W peak power for up to 1 minute from the same package”     

The unit is an extension to the firm’s GNT series of power supplies, which includes 30, 60, 200 and 400W models.

The supply has a convection rating as high as 150W. The company said it recognised the needs of customers who require higher power ratings without the need for fan cooling which, in addition to being acoustically noisy, also reduces the mtbf of the equipment. Medical manufacturers particularly do not like the ability of fans to spread dust and germs in critical surgery areas.

The power supply is available in seven standard versions with outputs ranging from 12 to 48V, although the company can offer the product with any other output within those parameters to suit customers particular requirements. All products have a single main channel and two auxiliary 12 and 5V outputs.

All units have, as standard, inhibit, enable, power signals and remote sense. Efficiencies achieved are high with 90 per cent achieved typically at 230Vac.
