Protection
|
Short Circuit Protection
|
When short-circuit occurs, the individual PTC fuse will break the circuit. When the fault is cleared, it will switch back to normal automatically.
|
|
High Voltage Protection
|
When over voltage occurs, it will switch to self-protection status to
protect the load.
|
|
Over Current Protection
|
When over current occurs,
the corresponding
channel output will automatically switch to self-protection status, and the other channels output will work normally. When the fault is cleared, it will switch back to normal.
