Overcurrent/overvoltage protection
If a short-circuit or other problem on the load side causes an excessive current flow or generates
abnormal voltage, the overcurrent/overvoltage protection systems automatically cut off the output
voltage to protect the power-supply circuit.
If the overcurrent or overvoltage protection system are activated and the power-supply circuit does not
generate DC voltage, turn the power off, correct the problem, and then turn the product on again.
The circuit has two fuses (FU1, FU2), which break and cut off the output voltage if overcurrent flows
through the alternating current (AC) line.
