Input Characteristics

*See Application Note 205 (Section 5.2) for manufacturer and part number.

All specifications are typical at nominal input Vin = 48 V, full load under any resistive load combination at 25 ˚C unless otherwise stated.

Input Characteristics - Overload

and Short Circuit Protection

For all above overload and short circuit conditions, the unit shuts off safely. The unit can be restarted, providing the fault condition is no longer present.
