Combining an optimised layout to facilitate natural air convection cooling with efficient switching topology, the OBM03 and OBP03 are designed for continuous output power operation of 100W and 200W respectively in natural convection environments. When extra power is required, with limited forced air, the output power can be increased up to 150W at 7.5CFM for the OBM03 and up to 300W at 10CFM for the OBP03.
The OBM03 and OBP03 are designed to withstand an input-to-output isolation of 4000Vac, input-to-ground of 1500Vac and output-to-ground of 1500Vac. At 264Vac the leakage current is below 275µA for the OBM03 and bellow 220µA for the OBP03.
In medical environments parasitic noise could impact on microvolt-sensors and other sensitive equipment. The OBM03 and OBP03 feature a built-in filter and loop-less layout meaning they meet EMC IEC60601-1-2 and ITE requirements, as well as EN55011/EN55022 class B both conducted and radiated.
With a nominal input voltage of 100 to 240V 50/60Hz, seven available output voltages spanning from 12 to 48Vdc and an operating temperature window of 0 to 70°C the power supplies suit a range of medical applications.
The Medline OBM03 and OBP03 are available in an open frame 50.8 x 101.6 x 33mm package, and in a low profile open frame 76.2 x 152.4 x 35.1mm package respectively. The OBP03 is also available in L-Bracket and Enclosed with integrated fan.
