Protection |
Over voltage protection |
When over voltage occurs, it will be 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 work normally, when clearing of fault, then switch back to normal. |
|
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. |
|
Charge |
The power supply will automatically switch to storage battery if there is outage. |
