Campbell Collins Ltd, a specialist supplier of power supplies, capacitors and hi-rel power semiconductors, is pleased to announce the release of the GRN series of high efficiency, compact AC/DC Power Supplies from IPD (Integrated Power Designs) of the USA. The 80W GRN series offers single output models in a 2.5" x 4.25" x 1" package, and dual, triple and quad output models in a 5" x 3" x 1" package. The devices have been designed specifically to offer extremely low profile solutions for 80W applications when compared to similar competitive devices. Single output variants are available from 3.3V to 48V, and multiple output variants offer different combinations of voltages from 3.3V to 24V, including negative output voltages. Efficiency levels are as high as 89%, leading to high power densities, small package sizes, cooler operating temperatures and higher overall reliability. This also saves energy for the user and hence ultimately lowers operating costs. The efficiency curve is also very flat across the entire load range, offering consistent results under different load conditions while still offering >85% efficiencies at very light loads. Operating temperature range is from 0°C to +70°C, with full power being available up to 50°C in natural convection environments (derates linearly to 50% available load at 70°C). The GRN offers internal hold-up from supply voltage interruptions for up to 16ms, and also meets the leakage current requirements of UL/EN60601-1 making them suitable for Medical applications as well as IT and Industrial applications. No minimum load is required to maintain output regulation, and MTBF figures are in excess of 100khrs according to Mil-Hdbk 217F. www.camcol.co.uk
