What are the key features of the CM4 AC-DC power supplies?

Posted by Martin on July 5, 2019

The CM4 series of 600W conduction cooled AC-DC power supplies is an ideal solution to power a wide range of medical and general applications where silent operation, or operation without a fan, is required and space is limited.

Featuring up to four outputs, the power supplies are capable of providing 600W continuous or 750W peak output power and are suitable for conduction cooling through the base-plate, forced air cooling or convection cooling. This means that the power supplies can supply their full output power at ambient temperatures of up to 50°C with either conduction or forced air cooling.

Measuring just 102mm x 178mm, with a profile of just 40mm, the power supplies suit a number of low-profile applications, enabling system designers to save valuable space and cut costs.

The CM4 range has medical approval to both IEC60601-1 3rd edition and IEC60950 for ITE, making it ideal for use in medical, healthcare and diagnostic equipment. They are also suitable for rugged environments, especially in applications requiring MIL-STD-810 shock and vibration specification. Suitable use cases can also be found in broadcasting, audio and video, as well as across various industrial applications such as process control.

The CM4 power supplies achieve class B rating for conducted and radiated EMI and come with a five-year warranty.
