Protection type:Shut down o/p voltage,re--power on to recover
Over voltage protection Shut down the output when non-load voltage≥13V,re-power on to recover after fault condition is removed. Shut down the output when non-load voltage≥26V,re-power on to recover after fault condition is removed
Over load protection Shut down the output when current load ≥110%, auto recovers.
Short circuit protection Protection type: 1. When the first-level short-circuit protection is triggered, the fault can be automatically recovered;2. When the second-level short-circuit protection is triggered, the power needs to be turned on again after the fault is eliminated
