The MFA160 medical grade AC/DC power supply series offers high efficiency >90%, conducted noise compliance to level B and a low leakage current. The series comes in 5, 12 and 24 VDC standard output voltages and offers an auxiliary 12 VDC, 0.5 A output. The 5V variant comes as IEC Class II and operator protection (MoOP), the 12V variant comes as IEC Class I and operator protection (MoOP), the 24V variant comes as both IEC Class I, MoOP and as IEC Class II, 2xMoPP patient protections. The series provides a steady 160 W of regulated DC power from an open-frame 2 x 4 x 1” standard form factor which eases integration into space constrained systems.
The MFA160 can deliver full output power from -20 to 50 °C at 500 LFM airflow and can be operated up to 70 °C applying output power derating. When natural convection cooled, the 12, 24V variants can deliver a steady 100 W, and the 5V, 70 W up to 50 °C ambient. All MFA160 variants can be operated up to 4000 m without de-rating thanks to PCB creepage and clearance greater than 8 mm.
Protection features include fuses on both AC lines, output over-current, short-circuit, output over-voltage and over-temperature. The MFA160 series complies with the 3rd edition of the IEC/EN 60601-1and ANSI/AAMI ES60601-1 safety standards for medical equipment. It meets the EN 60601-1-2 EMC limits of Class B for conducted emissions, the IEC/EN 61000-3 for harmonic content and EN 55011 / EN 660601-2 for EMC immunity.
