SOURce channel VOLTage PROTection UNDer LEVel Over Current Protection OCP The OCP alarm is a firmware alarm that is only configurable using the SCPI interface The OCP triggers if the output current exceeds the OCP set point Because the OCP alarm is a firmware based alarm it has a latency before detection of the condition can occur The user should be aware of this latency and take this into consideration when relying on OCP to protect a sensitive load The maximum period for detecting an OCP condition is 300 ms OCP is fixed at 110 of rated current 3 28 M370078 01 Using Over Temperature Protection Lock OTP Using Over Temperature Protection Lock OTP The OTP lock protects the power supply in the event of an over temperature alarm This alarm could be caused by ventilation restriction or overheating due to fan failure Two modes are available Auto recovery OTP OFF where the power supply turns on again after cooling down e Latch mode OTP ON where you will need to reset the unit by turning the front panel power switch to Off and then On again If the OTP is activated the main output will turn off and Prd over temperature protection will blink on the display The OTP alarm is an alarm that will auto recover when the temperature falls back into normal bounds Defining the OTP Mode To define the OTP lock 1 Turn the 9 position mode control to the PRT position Pr ULP is display
