For very sensitive applications, it maybe desirable to set OV level to a specific value, by following the steps below:
1) Determine the maximum voltage allowed by the your application (the OV limit). This should be slightly higher
than the operating voltage. If for whatever reason there is a voltage surge above this limit (measured at the output
terminals), the OV light will turn red, and the power supply will no longer respond to user input (with the output
turned off). For easier communication, we assume that 12.0V is the working voltage and 13.0V is the OV limit.
2) With no load connected, make sure the OV level (11) is set to maximum. Turn the power supply on.
3) Use knobs 12 and 13 to adjust the voltage to 13.0V; adjust current knobs if necessary to stay in CV mode.
4) Slowly turn the OV adjustment (11) counterclockwise, stop as soon as the OV light turns red. The OV limit is
set at 13.0V now.
5) To reset the power supply, turn the knob 12 and 13 counterclockwise to minimum position, and turn the power
supply off.
6) Once the power supply is completely off, turn it back on, and set the voltage to 12.0V. Note that if voltage is
set to higher than 13.0V, the OV protection will kick in.
