The Astrodyne TDI ASM201 series power supplies, including the ASM201-540-BEH-PF1 model, are high power density AC/DC converters designed for both medical and industrial applications. They operate over a wide input voltage range of 80 to 264 VAC at 50-60Hz, delivering up to 200 Watts of regulated DC output power.
This specific model, ASM201-540-BEH-PF1, provides a 54V output with a maximum current of 3.7A, offering 140W in convection cooling and 200W with forced air. It features high efficiency up to 95% at 230 VAC and a wide operating temperature range from -40°C to +85°C with derating. Safety approvals include IEC 60601-1, IEC 62368-1, and IEC 60950-1, making it suitable for patient safety applications with 2 MOPP isolation and BF leakage current.
The power supply is housed in an enclosed form factor with chassis mount type, measuring 105.9mm x 68.1mm x 39.9mm. It includes features like universal input, power good signal, and protection against over current, short circuit, over voltage, and over temperature.
Compliance includes RoHS3, REACH Unaffected, and DoE Efficiency Level VI. The ASM201 series is approved for home medical usage and meets EMC standards like EN60601-1-2 Class B.
The output voltage is 54VDC. The maximum output power is 140W under natural convection and 200W with forced air cooling (≥14 CFM).
The AC input voltage range is 80-264VAC at 47-63Hz.
It provides 4000VAC input-to-output isolation (2 MOPP), 2000VAC input-to-earth (1 MOPP), and 1500VAC output-to-earth (1 MOPP).
The operating temperature range is -40 to +55°C at full load (140W convection or 200W forced air), and up to +85°C with derating.
Over current protection (110-160% rated current), short circuit protection (hiccup mode, auto recovery), over voltage protection (105-140% Vout, latching), and over temperature protection (auto recovery).
Efficiency is up to 95% at 230VAC.
Dimensions are 105.9mm x 68.1mm x 39.9mm (4.17" x 2.68" x 1.57") or 2 x 4 x 1.11 inches. Weight is 620g (1.37 lbs).
