Medical power supply delivers power and safety to healthcare facilities at altitude

Powerbox has launched a new series of power supplies for medical applications requiring BF (Body Floating) class insulation and full, stable operation up to 5,000m altitude to power medical healthcare facilities and equipment. Complying with the newest EMI coexistence standard IEC 60601-1-2: 2014 (4th edition) and specifically designed with patient and operator safety in mind, the OBR04 series delivers an output power of 650W. The device is offered in 12 different voltages from 12V to 58V with an efficiency rating up to 91%. With a strong focus on ‘no interference and radio coexistence’, the device meets conducted and radiated EN55011 class B without requiring any additional components. Built to ensure patient and operator safety, the device has an input-to-output isolation of 4,000VAC (2xMOPP), an input to ground of 1,500VAC (1xMOPP) and a 1,500VAC output-to-ground, when many conventional products offer only 500VDC isolation. To guarantee full operation up to an altitude of 5,000m, the OBR04 has been designed in respect of required creepage distances and additional isolation barriers.
