Powerbox OBR04 series power supplies for medical applications meet BF (Body Floating) class insulation requirements and provide reliable operation at altitudes up to 5,000 meters. Complying with EMI coexistence standard IEC 60601-1-2: 2014 (4th edition), the series delivers an output power of 650W and is available in 12 different voltages from 12V to 58V with an efficiency rating up to 91%. The supplies also meet conducted and radiated EN55011 class B without requiring any additional components. In terms of patient and operator safety, the OBR04 has an input-to-output isolation of 4 kVac (2xMOPP), an input to ground of 1.5 kVac (1xMOPP) and a 1.5 kVac output-to-ground.
The OBR04 is available as standard in twelve output voltages; 12, 15, 18, 24, 28, 30, 32, 34, 36, 48, 57 and 58 Vdc. Depending on the output voltage the maximum output power starts at 600W and rises to 650W with a peak power level of up to 720W. An auxiliary 12V output is provided for an additional fan, as well as a standby 5 Vdc supply at 200 mA.
Housed in an aluminum chassis, dimensions are 165.8 mm x 101.6 mm x 62.5 mm (6.53 x 4.0 x 1.95 inches) and it is available in a ‘U’ shape chassis or an enclosed box with built-in fan. Based on a calculated MTBF per MIL-HDBK-217F, at full load and at 25 degrees C, the OBR04 has a MTBF of 190,000 hours. Thirsting for even more details and spec?
