CNS658-MU

## **ARTESYN CNS650-M SERIES** 650 W AC-DC Power Supplies 

Advanced Energy's Artesyn CNS650-MU series of single output open-frame AC-DC power supplies are offered 12 V, 24 V, or 48 V outputs with +15% trim range. Each power supply comes with a 12 V fan output and 5 V standby. All models feature ITE and medical safety approvals and accept a universal input of 90 to 264 VAC. Depending on operating conditions, its 4'' x 6'' x 1.54'' compact and high density "U-Channel" construction delivers up to 400 W of output power with free air convection cooling and up to 650 W with 400 LFM of forced air. These power supplies are ideal for industrial systems as well as for medical applications.
