1100W medical power supply complies with latest IEC60601-1-2 standard

April 06, 2016 // By Julien Happich
Complying with the latest EMI coexistence standard IEC 60601-1-2: 2014 (4th edition) and specifically designed with patient and operator safety in mind, the OBS01 series from Powerbox delivers an output power of 1100W (1250W peak during 10s under specified conditions).

The unit is available in seven different voltages from 24 to 48V with an efficiency up to 89%. With high focus on “no interference and radio coexistence,” the product meets, conducted and radiated EN55011 class B, without requiring any additional components. Built for patient and operator safety, 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.

To guarantee OBS01 will operate, in controlled and non-controlled radio environments, the product successfully 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. The OBS01 series is housed in a six sided shielded metal case measuring 150x235x61mm. Two fans with speed control are placed on the rear panel, guaranteeing optimized cooling.
