3.5 PROTECTION FEATURES
There are four protection functions for the SLM-Series Electronic Load: Over-Voltage,
Over-Current, Over-Power and Over-Temperature. When the electronic load exceeds
the normal work area range, one of these four functions will activate. This feature turns
OFF the load to protect it from damage. The lower digital meter flashes the protection
status notice, indicating which protection function is active.
3.5.1 Over Voltage Protection (OVP)
The over voltage protection (OVP) point is preset in the SLM-Series AC/DC
Electronic load. Table 3-5 shows the OVP trip values for the various models in the
series. When OVP occurs, the lower digital meter (DM) flashes "oVP". Once the
over voltage condition is reset, the lower DM resumes normal display.
3.5.2 Over Current Protection (OCP)
The over current protection (OCP) point is preset in the SLM-Series AC/DC
Electronic load. Table 3-5 shows the OCP trip values for the various models in the
series. When OCP occurs, the lower digital meter (DM) flashes "oCP". Once the
over current condition is reset, the lower DM resumes normal display.
3.5.3 Over Power Protection (OPP)
The over power protection (OPP) point is preset in the SLM-Series AC/DC Electronic
load. Table 3-5 shows the OPP trip values for the various models in the series.
When OPP occurs, the lower digital meter (DM) flashes "oPP". Once the over power
condition is reset, the lower DM resumes normal display.
