Longxc Launches ACMS45A: Compact and Reliable 50W Built-in AC/DC Power Module
Introduction
Power supplies usually fly under the radar, but they’re what keep devices running. Longxc’s new ACMS45A 50W built-in AC/DC module is small but mighty, perfect for gear where space is tight but stable power is a must.
Compact Size, Big Performance
Don’t let its size fool you. Measuring just 76.2×50.8×18.0mm, the ACMS45A puts out a steady 50W and can handle up to 80W peak. It’s ideal for compact medical devices like monitors, ventilators, or ultrasound machines—where every inch counts but you still need reliable performance.
Flexible Input and Smart Protections
It works anywhere thanks to its 90–264Vac input range. And to keep things safe, it comes with built-in protections:
- Short-circuit protection with automatic reset
- Over-current protection at 110%–200% of load
- Over-voltage protection at 110%–150% of output
These features help devices stay safe even when things get unpredictable.
Ready for Medical Use
Safety certifications matter for medical equipment. The ACMS45A ticks all the boxes: UL60601-1, EN60601-1, CB, and TUV, plus it meets IEC/EN60601-1-2 EMC standards. That means it’s safe to use in hospitals and clinics.
Reliable in Any Condition
Whether it’s powering patient monitors, lab devices, or rehab equipment, the ACMS45A keeps things running smoothly. With up to 86% efficiency and a temperature range of -20°C to +70°C, it’s built to handle tough conditions without breaking a sweat.

Bottom Line
Devices are getting smaller and smarter, so power supplies need to keep up. The ACMS45A combines compact design, efficiency, and safety in one neat package. For anyone looking for a reliable, certified power solution, it’s a solid choice.
