Operation
Sorensen SLH-Series DC High Power Electronic Load
3.10.2 Over Current
•
The protection point of over current protection (OCP) is preset in the load. The
activation values of the OCP circuit are shown in Table 3-3.
•
When an over-current condition occurs, the OCP circuit is activated, and the lower 5-
character monitor on the front panel of the electronic load flashes “oCP”. The load will
automatically go to a LOAD OFF state.
•
Once the over current condition is reset, the lower 5-character monitor will resume
normal operation.
3.10.3 Over Power
•
The protection point of over power protection (OPP) is preset in the load. The activation
values of the OPP circuit are shown in Table 3-3.
•
When an over-power condition occurs, the OPP circuit is activated, and the upper 5-
character monitor on the front panel of the electronic load flashes “oPP”. The load will
automatically go to a LOAD OFF state.
•
Once the over power condition is reset, the upper 5-character monitor will resume
normal operation.
3.10.4 Over Temperature
•
SLH-Series DC electronic loads also are designed with a temperature sensor(s) for over
temperature protection (OTP). The activation values are shown in Table 3-3.
•
When an over-temperature condition occurs, the OTP circuit is activated, and the lower
5-character monitor on the front panel of the electronic load flashes “otP”. The load will
automatically go to a LOAD OFF state.
•
When OTP occurs, please check the environment condition such as the ambient
temperature and distance between the rear panel of Electronic load mainframe and wall
is greater than 6in. / 15cm.
•
Once the over temperature condition is reset, the lower 5-character monitor will resume
normal operation.
