Medistax MM1U Series
Medically Approved 1U high Configurable Modular, Switch Mode Power Supplies
of up to 1,450W from Powerstax plc.

Powerstax MM1U range of Ultra Low Profile Configurable SMPS with medical pre-approval
The MEDISTAX® family of power supplies provides an incredible 1200W of modular and configurable power in an extremely compact 1U high (40mm) package with up to 12 isolated outputs.
Employing an innovative plug & play architecture the MEDISTAX® units combine feature-laden front-end Power Units combined with slide-in output converter modules, that allows configuration of a custom power solution in less than 5 minutes.
Medically Approved, all configurations carry full safety agency approvals including UL2601-1, EN60601-1 and are CE marked.
Ultra high efficiencies of over 90% significantly reduces system thermal load and an industry leading 15W/in³ power density provides a compact and versatile power solution. Less than 300µA leakage current and 4000VAC isolation plus the MM1U is available in 4 and 6 slot versions.
The non-medical MS1U range - including a family designed specifically for extended temperature applications fully specified from -20°C to +70°C with no derating and a range designed specifically for acoustically sensitive applications also available - contact Powerstax for further details
