## CUS800M 1000M and 1200M Series , 

## 1.67”High 800W to 1200W AC-DC Power Supplies 

The very compact CUS800M, CUS1000M and CUS1200M AC-DC power supplies have a low profile 1.67” (42.5mm) high package and can deliver 800W, 1000W or 1200W with efficiencies up to 95.5%. All models have medical (IEC 60601-1) and audio/video, information and communication technology equipment (IEC 62368-1) certifications. A variable speed fan, 5V 2A standby voltage, remote on/off, remote sense and a Power Good signal is standard. 

|**Features**|**Benefits**|
|---|---|
|• Medical Certifications (2 x MOPP)|• Generally required for B and BF Type Medical Equipment|
|•<0.250mA Leakage Current|• Simpler System Compliance|
|• Class B Conducted and Radiated EMI|• Easier System EMC Compliance|
|• Compact 1.67” Height|• Space Saving in End Equipment|
|• Variable Speed Cooling Fan|• Lower Audible Noise|

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
