The Astrodyne TDI ASM40 series, including the ASM40-5A model, offers 40W ultraminiature medical open-frame switching power supplies. These converters are engineered for both medical and industrial applications, operating from a universal AC input range of 90-264 VAC at 50/60Hz. The ASM40-5A provides a regulated 5VDC output with a maximum current of 8A, delivering up to 40W of power.
Designed with safety and reliability in mind, the ASM40 series holds safety certifications to IEC60601 for medical applications, including home use. It complies with IEC 60601-1-1, 3rd Edition, Amendment 1, and meets EMI standards EN55011 Class B. Key electrical specifications include 4000VAC isolation, ±1% load regulation, and ±1% line regulation for single outputs. The unit operates within a temperature range of -20°C to 50°C with derating.
The ASM40-5A features a compact open-frame design with chassis mount capability, measuring 101.6mm x 50.8mm x 31.6mm. Its universal input and robust protections, such as over-voltage, overpower, and short-circuit protection, make it suitable for demanding environments. The efficiency is rated at 77% typical.
