Notes:
1/
Parameters not tested but are guaranteed to the limits specified in the table.
2/
Recovery time is measured from the initiation of the transient to where VOUT has returned to within
± 1 percent of V
OUT at 50 percent load.
3/
Line transient transition time
≥10 microseconds.
4/
Turn on delay is measured with an input voltage rise time of between 100 and 500 volts per millisecond.
5/
Current limit point is that condition of excess load causing output voltage to drop to 90% of nominal.
6/
Parameter verified as part of another test.
7/
All electrical tests are performed with remote sense leads connected to the output lead at the load.
8/
Input step transition time
≥100 microseconds.
9/
Enable inputs internally pulled high. Nominal open circuit voltage = 4.0VDC.
