2.3 Output over-current protection
zAEW series DC/DC converters feature Over-current Protection (OCP) circuits.
When output current exceeds 110% to 150% of rated current, such as during a short
circuit condition, the output will shutdown immediately, and can tolerate short
circuit conditions indefinitely.
zWhen the overcurrent condition is removed, the converter will automatically
restart.
2.4 Output over-voltage shutdown (OVP)
zThe AEW series provides over-voltage protection on the output, which will
shut the output off if the voltage exceeds 116 to 150% of the nominal output
voltage, and the output is shutdown.
zIt must power the module on again to recover the output.
zIf the module is trimmed up to the voltage, which exceeds the 110% rated
output voltage, the output over-voltage protection will be probably triggered
off.
zFor dual output products:
Through testing the over-voltage condition between +Vo and –V, the
over-voltage protection active (operating at 116% 150% rated output
voltage).
zFor triple output products:
Through testing the over-voltage condition between +Vo and COM, the
over-voltage protection active. When Vo1 exceeds 116%~150% rated output
voltage, the over-voltage protection active. After the protection, please turn off
the power supply, and restart after 2-3 seconds, the output will be normal.
