AC/DC Power Supplies for Medical Applications

While from Delta Electronics the Open Frame version MEU-600C24 with 600W and optionally 24VDC or 48VDC convection cooled with U-channel is available, the MEB-1K2A was designed as a chassis power supply with 1200W power, 24VDC or 48VDC output voltage. This means a power increase of 20% with the same form factor. Both products are approved to EN/IEC/UL60950-1 (ITE standard) and EN/IEC/UL60601-1-2 4th Edition (medical standard) and have a wide input voltage range from 85 to 264VAC and an operating temperature range from -20 to +70°C, operating at full power up to +50°C.

Additional features are the included active current distribution in parallel operation, an analog (+/-10%) and digital voltage setting (PMBus) and the choice between "Remote On/Off", both in normal and inverted logic controllable. In addition, the MEB-1K2A24 has an intelligent fan speed control to minimize ambient noise and still ensure an optimal cooling function. Both units have an MTBF of up to 500,000 hours and are particularly suitable for use in medical applications with 2 x MOPP insulation requirements; Type BF.
