OCP Mode switch set to position 1 I A peak load of up-to 150% can be taken for a given duration. This duration depends on the percentage of peak load taken and can be determined by graph A below. T-peak I-peak If the load is reduced to less than 100% of nominal either before or at the end of the duration, then there is a period of recovery needed to allow the power supply to cool down before the peak load can be re-applied. The time required for recovery depends on the amount of reduction of load and can be determined by graph B below. I-recovery T-recovery 0 T However, if the peak load period exceeds the duration indicated by graph A the output will go into constant current mode for protection. The constant current value will be 105% of the nominal rating. During constant current operation, if the output voltage should fall below 40% of the rated voltage then the output will turn off and try to restart for five times before turning off permanently. Once this has happened, the output will need to be reset by turning the AC mains off and on again. A peak load of up-to 150% can be taken for a given duration. This duration depends on the percentage of peak load taken as described by graph A. OCP Mode switch set to position 2 I Once the peak load duration is exceeded, the output will turn off for 3-4 seconds before automatically restarting.

The effect of the control is dependant upon the RC switch setting on the front panel. If the switch is set to position 1 then the output can be disabled by applying a suitable voltage. If the switch is set to position 2 then the output can be enabled by applying a voltage. In the range of 2.5 V to 9.0 V limited to 20 mA.
