Protective control
The low-voltage power supply has protective controls against excessive current and voltage,
which automatically detect excessive current or abnormal voltage to shut off the output
voltage for avoiding the power supply circuit failures.
In case the DC voltage output is not detected from the low-voltage power supply, the
protective control may be activated. Turn off the power switch and remove the AC power
supply from the inlet to settle load troubles. Once these are settled, turn on the power switch
again.
Another protective control is provided by 2 power fuses on the fixing power supply. These
are open when excessive current is detected to shut off power supply to low-voltage power
supply.
