CPS255-M Description

Short technical summary and product information.

The Artesyn Embedded Power CPS255-M series offers versatile AC-DC power conversion solutions designed for both industrial and medical applications. These open-frame power supplies feature a compact 2" x 4" footprint and a height of just 1.29 inches, making them suitable for space-constrained designs.

 

With a total power output of 250W under forced air cooling and 155W under natural convection, the CPS255-M series provides flexibility for various operating conditions. The input voltage range is a universal 90 to 264 VAC, complemented by Active Power Factor Correction compliant with 61000-3-2.

 

Key features include medical and ITE safety approvals, a built-in Class B EMI filter, and a low no-load power consumption of less than 500 mW. The power supplies are designed for forced air and natural convection cooling and offer an adjustable output with a +10% trim range. They also include a 12V fan output and, on specific models like the CPS253-M1, a standby output and remote On/Off control.

 

These converters are ideal for light industrial systems and medical applications requiring reliable power. They are safety-certified to standards including EN 62368-1, UL/CSA 62368-1, and IEC 60601-1, with specific testing according to the medical standard IEC 60601-1-2 4th Edition.
