5. Protection
This subsection is relevant to user-programmable protection, not internal hardware protection.
‘OPP’ (over power protection): setting range is from 0 through 1.02 times of rated power.
‘OCP’ (over current protection): setting range is from 0 through 1.02 times of rated current.
‘OCP Delay’: setting range is from 0 through 5s.
‘CC (constant current) Mode’: in this mode the output voltage will be automatically decreased
to limit the output current when the output current increases too much.
For example, to set the OPP level.
1. In the ‘Protection’ mode screen, move the cursor to highlight ‘OPP =’ field, press [0]~[9] nu-
mber keys as desired then press the [Enter] key to confirm.

If the output current greater than 1.05 times of the OCP setting, the output will shut down
in about 500ms. If the output current less than 1.05 times of the OCP setting, the output
will shut down in the delay time setting, which range is from 0 through 5s.
