2MOPP Certified for Patient Safety

Designed with 2MOPP reinforced insulation and 4000VAC I/O isolation, the MQCS100 power module meets global medical safety standards (UL / IEC / EN 60601-1) and protects patients and operators alike in contact-critical systems. The power module also passes strict EMC compliance without the need for external components, helping engineers simplify certification and integration.

Compact, Stable, and Integration-Ready

With a 90–264VAC universal input, and an operating range from -30°C to +70°C, the MQCS100 power module ensures stable output even under fluctuating power conditions. Its compact footprint is ideal for space-limited medical designs, while its robust thermal and electrical performance makes it suited for extended operation in clinical environments.

Flexible Mounting for Any Application

In addition to PCB mounting, the MQCS100 power module also offers a Screw Terminal option, providing greater installation flexibility for medical device designs where direct board mounting isn’t feasible. This feature makes it easy to deploy in a wide range of medical hardware configurations.

ARCH MQCS100 is more than a power supply—it’s peace of mind for mission-critical medical systems.

When power matters most, trust the only 100W encapsulated module built specifically for medical use.
