These modules operate over a wide input voltage range (VIN = 18/20 – 30Vdc) and provide a precisely regulated output voltage from 3 to 6Vdc (AXB030) and 5 to 15Vdc (AXB050), programmable via an external resistor. Standard features include remote On/Off, adjustable output voltage, remote sense, over current and over temperature protection. * UL is a registered trademark of Underwriters Laboratories, Inc. † ‡ CSA is a registered trademark of Canadian Standards Association.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

To preserve maximum flexibility, no internal fuse has been provided. Also, extensive safety testing has shown that no external fuse is required to protect the unit. However, it is still recommended that some type of current-limiting power source be used to protect the module and evaluated in the end-use equipment.
