40W Regulated Output PCB Mount AC-DC Encapsulated Power Module

MSC Series

40W Board Mount AC to DC Medical Power Conversion (Module)- One Module. Multiple Outputs. Medical Safety Without Compromise.

The ARCH MSC is a compact and versatile 40W AC-DC encapsulated power module built specifically for medical applications that demand high safety, reliability, and flexible power delivery. Unlike conventional medical power modules that only provide a single output, the MSC power module offers single, dual, and triple output configurations—allowing you to power multiple voltage rails from a single unit. This not only simplifies your power architecture but also helps reduce component count, save board space, and lower overall system cost—an advantage no competing product currently offers.

Medical-Grade Safety You Can Trust

Designed for patient-connected and life-critical applications, the MSC power module is fully certified to UL / IEC / EN 60601-1, and delivers reinforced isolation with 2MOPP for maximum protection. With a 4000VAC I/O isolation barrier, it ensures operator and patient safety, while complying with the strictest international medical standards. Whether it's for diagnostic imaging, infusion systems, or patient monitoring, the MSC power module provides the safety foundation your design requires.

Compact, Efficient, and Easy to Integrate

With a universal 90–264VAC input range and a -25°C to +70°C operating temperature, the MSC 40W power module performs reliably across global voltage conditions and standard clinical environments. Its cost-effective and compact design makes it easy to integrate onto space-limited PCBs, perfectly suited for today's smaller, smarter medical devices.

More outputs. More flexibility. One certified solution

The ARCH MSC40 redefines what a medical-grade power module can do—delivering safety, versatility, and efficiency in a compact package no competitor can match.
