The unit will shut down when the input voltage drops below a threshold, and the unit will turn on when the input voltage goes to the upper thershold. The hystersis voltage of the unit voltage protection is 0.5V, normally from the 8V to 7.5V range. CH1:+5Vout/short Ch2:-12Vout/short CH3:-12Vout/short Output over current protection(OCP) and output short protection The unit will auto recovery current limit when the over current or short circuit condition exists. Once the OCP happens, the unit has auto recovery current limit . The attempted restart will continue indefinitely until the over current or short circuit condition is removed. When OCP happens, the output voltage drops below 0V.
