650W medical power supply delivers 450w without fans

by | Jun 9, 2021 | Delta, Medical, Press release

The new MEU-650A24T medical power supply from Delta Electronics supplies 24V in a very small 4″ x 6″ form factor, providing up to 650 W with forced air cooling or 450 W when convection cooled. This 95.5% efficiency power supply is suitable for BF type medical equipment and general IT equipment

It is equipped with a 12 V / 0.6 A fan output and 5 V / 2 A standby output. High efficiencies of up to 95.5% and a wide operating temperature range of -20°C ~ 70°C mean that the MEU-650A24T is suitable for various applications such as ultrasound, anaesthesia and other medical equipment. Featuring 2 x MOPP Isolation, these medical power supplies have onboard current sharing technology enabling 2 units to be paralleled together to increase the power supplied.

This family which will be added to with 12V and 48V variants later this year, is also suitable for many industrial applications with major approvals including IEC/EN/CSA 60601-1 (Medical), IEC 60950-1, and IEC/EN/UL/CSA 62368-1 (ITE) including IEC/EN 60335-1 and IEC 61558-1 (Household appliances). The MEU-650A24T is also certified with EMC standards EN 55011 for industrial, scientific and medical (ISM) radio-frequency equipment, and EN 55032 for Information Technology Equipment (ITE) radio-frequency equipment; as well as full compliance with RoHS Directive for environmental protection.
