34 PRODIGIT
3-10 Protection Features
There are four protection functions for the 3260A Series High Power Electronic Load, namely,
Over-Voltage, Over-Current, Over-Power and Over-Temperature. When electronic load
exceeds the normal work area range, one of the above 4 functions will come to effect. When
any one protection comes to effect, load will be changed to OFF to protect electronic load
thus preventing damage resulting from abnormal operation range. Also, protection status is
indicated by flickering to allow the user understand present condition. Various protection
functions are cited below:
3.10.1 Over Voltage
The protection point of over voltage protection (O.V.P.) is preset in the 3260A series
High Power electronic load. The setting values of over voltage protection are shown
on table 3-12. When O.V.P occurs, the 4 1/2 digit monitor on the upper side of the
front panel of 3260A series High Power electronic load will display
〝
oVP
〞
with
flickering to indicate
〝
Under Protection
〞
. Once the over voltage condition
disappears, the upper 4 1/2 digit monitor will resume to normal condition.

3.10.2 Over Current
The protection point of over current protection (O.C.P.) is preset in the 3260A series
High Power electronic load. The setting values of over current protection are shown
on table 3-13. When O.C.P. occurs, the 4 1/2 digit monitor on the lower side of the
front panel of series High Power electronic load will display
〝

.Once the over current condition disappears, the lower 4
1/2 digit monitor will resume to normal condition.
