With focus on “no interference and radio coexistence,” the product meets conducted and radiated EN55011 class B, without requiring any additional components. The OBS01 has an input-to-output isolation of 4000 VAC (2xMOPP), an input to ground of 1500 VAC (1xMOPP) and a 1500 VAC (1xMOPP) output-to-ground when many conventional products offer only 500 VDC isolation.
The company notes that in 2014, regulatory bodies released a new revision of the norm IEC 60601; focusing on Electro Magnetic Interference IEC 60601-1-2:2014. In the USA all medical products will have to comply with the 4th edition, by April 2017
To achieve “no-interference and radio coexistence”, by thoroughly selecting filtering components with special attention to the layout, the OBS01 design is optimised to meet EN55011:2009 and CISPR 11:2011 class B conducted and radiated. Class B performance is obtained without requiring external components. The product passed all immunity tests including ESD 15 KV air and 8 KV contact as well as exposition to radio signals in compliance with the new levels set in the 4th edition such as Magnetic Immunity (IEC 61000-4-8) 30A/m, Radiated Immunity (IEC 61000-4-3) 10V/m complying with the new category Home Healthcare and to the new Proximity Field from Wireless Transmitters 9 V/m to 28 V/m at 15 specific frequencies.
The series includes seven output voltages 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). At operational power (1100W) and 230 VAC input the OBS01 as an efficiency up to 89%.
Based on MIL-HDBK-217F, at full load and 25°C the OBS01 has an MTBF of 300,000 hours. OBS01 includes overvoltage and overcurrent protections, thermal shutdown and includes standard PS OFF and DC OK signals. The series is housed in a six sided shielded metal case, with dimensions of 150 x 235 x
