Minimum load
B-XM-2WSeries
The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading
will result in an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.
Capacitive loading and start up
Typical start up times for this series, with a typical input voltage rise time of 2.2s and output capacitance of 10F, are shown in the table below. The product
series will start into a capacitance of 47F with an increased start time, however, the maximum recommended output capacitance is 10F.

Tolerance envelope
The voltage tolerance envelope shows typical load regulation characteristics for this
product series. The tolerance envelope is the maximum output voltage variation due
to changes in output loading.
