The Inventus Power MWA020005B-10A is a 20-watt Class II medical desktop power supply designed for reliable operation. It provides a stable 5V output at 4A, with a total regulation of ±5% and a ripple and noise level of less than 1% peak-to-peak.
This power supply features high efficiency, meeting Level V standards, and operates within a wide input voltage range of 85-264VAC. It includes essential protections such as over-voltage, over-current, and short-circuit protection with auto-restart.
The unit is certified to EN60601-1 Class II 3rd Edition for medical applications and meets EMC safety standards IEC/EN 60601-1-2 3rd edition. Its compact dimensions are 87.7mm x 51.8mm x 33.0mm, making it suitable for desktop use. The input connector is an IEC 320-C8 receptacle, and the output is delivered via a 2.5mm I.D. x 5.5mm O.D. barrel plug with a positive center.
Key features include low leakage current, a 5-year limited warranty, and an MTBF of over 200,000 hours. The operating temperature range is 0-60°C, with derating at higher temperatures. An AC power cord is not included and must be ordered separately.
The input voltage range is 85-264VAC (100-240VAC nominal) at 47-63Hz.
The output is 5V DC at 4A, providing 20W of power.
It is a desktop (Class II) adapter with an IEC 320-C8 input receptacle and a barrel plug output (2.5mm ID x 5.5mm OD x 9.5mm, positive center).
The operating temperature range is 0°C to 60°C, with full load up to 40°C and linear derating to 50% load at 60°C.
It meets Efficiency Level V with typical efficiency of 83% at 230VAC and 80% at 115VAC.
It is certified to EN60601-1 Class II 3rd Edition (medical safety) and IEC/EN 60601-1-2 (EMC), with approvals from CB, CE, and cTUVus.
The adapter includes over-voltage protection (110-135%), over-current protection (108-180%), and short-circuit protection (shutdown with auto-restart hiccup mode).
