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.
