Description

 

The AD24-12 & AD24-24 module are a series of isolated, Fly-back digital power supply that operate from a input range 85 to 265VAC (47~63Hz). These digital power supplies are available in a range of output voltage 12V and 24V, continuous 24Watts output capability. They are packaged in an EI-57 standard UL 94V-0 plastic enclosure; plug is 3 prong US type. Standard features include over current and short circuit protection. The efficiency is 80% minimum under 25% to 100% load condition. Typical applications include IT peripheral, home security data access system and other computing and communications equipment.
