The Astrodyne TDI ASM40 series, including the ASM40-12 model, offers 40W ultraminiature medical open frame switching power supplies. These converters are engineered for both medical and industrial applications, operating with a universal AC input range of 90 to 264 VAC at 50/60Hz. The ASM40-12 provides a regulated 12VDC output.
Designed with safety in mind, this series holds safety certifications to IEC60601 for use in various medical environments, including home healthcare. It complies with IEC 60601-1-1, 3rd Edition, Amendment 1, and meets EMI standards EN55011 Class B. Key electrical specifications include a typical efficiency of up to 86%, 4000VAC isolation, and protections such as over-voltage, over-power, and short-circuit.
The physical dimensions are compact, measuring 4 x 2 x 1.24 inches (101.6 x 50.8 x 31.6 mm), making it suitable for 1U compatible height requirements. The mounting type is chassis mount, and it utilizes convection or forced air cooling. The operating temperature range is specified as -10°C to +60°C, with some derating noted in other sources.
