Parameters not 100% tested but are guaranteed to the limits specified in the table.
Recovery time is measured from the initiation of the transient to where Vout has returned to within
±1.0%
of
Vout at 50% load.
Line transient transition time
≥
100µs.
Turn-on delay is measured with an input voltage rise time of between 100V and 500V per msec.
Current limit point is that condition of excess load causing output voltage to drop to 90% of nominal.
Parameter verified as part of another test.
All electrical tests are performed with the remote sense leads connected to the output leads at the load.
Load transient transition time
≥
10µs.
Enable inputs internally pulled high. Nominal open circuit voltage
≈
4.0VDC.
Load current split equally between +Vout and -V out.
Output load must be distributed so that a minimum of 20% of the total output power is being provided by one of
the outputs.
Cross regulation measured with load on tested output at 30% of maximum load while changing the load on
other output from 30% to 70%.
All tests at no-load are performed after start-up of the converter. The converter may fail to start when the output
load is less than 1.0W. Under these circumstances, the converter’s start-up circuitry will continue to cycle until
an adequate load is present.
