The Astrodyne TDI ASM40 series is a line of 40W ultraminiature medical open frame switching power supplies. Designed for both medical and industrial applications, these power supplies operate over a universal input voltage range of 90 to 264 VAC at 50/60Hz.
This specific model, the ASM40-12A, provides a single 12VDC output with a maximum current of 3.4A, delivering up to 40W of regulated DC power. It boasts high efficiency up to 86% and features 4000VAC isolation. The power supply complies with IEC60601-1 3rd Edition standards, making it suitable for a wide variety of medical applications, including those in home healthcare settings.
The ASM40-12A has a compact open frame form factor with dimensions of 4 x 2 x 1.244 inches (101.6 x 50.8 x 31.6 mm), designed for chassis mounting. It operates within an ambient temperature range of -10°C to +60°C, with convection and forced air cooling. Protections include over-voltage, over-power, and short-circuit protection, all with self-recovering capabilities.
Key electrical specifications include a wide input frequency range of 47-63 Hz, load regulation of ±1% for single output, and line regulation of ±1% max. Safety agency approvals include CB, CE, cURus, and UL, further ensuring its suitability for critical medical equipment.
