A series of power supplies for medical applications BF (Body Floating) has been announced by Powerbox. Complying with IEC 60601-1-2: 2014 (4th edition), the seven devices in the OBS01 series deliver 1100W, but can support peak demands of 1250W.A series of power supplies for medical applications BF (Body Floating) has been announced by Powerbox. Complying with IEC 60601-1-2: 2014 (4th edition), the seven devices in the OBS01 series deliver 1100W, but can support peak demands of 1250W.
Offering an efficiency of up to 89%, the devices are said to meet conducted and radiated EN55011 class B requirements without the need for additional components.
Devices in the OBS01 range can withstand 4000V AC from input to output, providing 2 x MOPP (means of patient protection), 1500V AC from input to ground (1 x MOPP) and 1500V AC from output to ground (1 x MOPP). Earth leakage current is said to be lower than 300µA.
The seven devices in the series offer: 24V/45.84A (peak 52.10); 28V/39.29A (44.65A); 32V/34.38A (39.07A); 34V/32.35A (36.77A); 36V/30.56A (34.73A); 42V/26.20A (29.77A) and 48V/22.92A (26.10A).
“The OBS01 range is the result of two years of R&D and technical innovations bringing to our customers a power supply which has the highest power density on the market, the lowest EMI, while keeping the leakage current below 300 µA, which requires state of the art technology,” said Martin Fredmark, vp of product management. “The OBS01 guarantees the best performances to power demanding medical applications, working fully coherently within complex radio environments.”
