ABSOLUTE MAXIMUM RATINGS
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional
operation of the device is not implied at these or in any other conditions in excess of those given in the operational
sections of the specs. Exposure to absolute maximum ratings for extended periods can adversely affect device
reliability.

Note: 1. This power module is not internally fused. The use of an input line fuse (GMA-10A Bussman fuse or
equivalent) is recommended.
2. The value is static only and rated for UL/cUL safety. In-rush current to charge internal capacitors is not
specified.
