CPS256-M Description

Short technical summary and product information.

The Artesyn Embedded Power CPS256-M series provides 250W of power in a compact, open-frame AC-DC conversion solution. Designed for versatility, it accepts a universal input voltage range of 90 to 264 VAC and delivers a single output with an adjustment range of -0%/+10%. This power supply is suitable for both ITE (Commercial) and Medical applications, boasting approvals from agencies like UL, CSA, CE, and CCC.

Key electrical specifications include a typical efficiency of 93% and active Power Factor Correction (PFC) compliant with 61000-3-2 Class A. It features a 12V fan output and a standby output (for CPS253-M1 only). The unit is designed for forced air cooling, delivering up to 250W, or natural convection cooling, providing up to 155W. Its dimensions are 4.00" L x 2.00" W x 1.29" H (101.6mm x 50.8mm x 32.8mm), making it suitable for space-constrained designs.

Environmental and safety features include a wide operating temperature range from -20°C to 70°C (with derating) and compliance with medical standards like IEC 60601-1-2. It also incorporates a built-in Class B EMI filter and meets surge immunity Level 3 requirements. The power supply is rated for 4kV isolation and offers overvoltage, overcurrent, short circuit, and overtemperature protection with auto-recovery.
