Short Circuit Protection (Overcurrent Protection) When +5V DC circuit is shorted, the output drops. The output auto-recovers in 10sec after recovery from the short. Overvoltage Protection When +5v DC output reaches +6-8V DC, the output is cut off. The output recovers at power on 60sec after power off.
