basic power supply functions from the control panel. Operations that you can perform are:
■ Enabling or disabling the power supply output
■ Setting the output voltage and current
■ Monitoring the output voltage and current
■ Setting the overvoltage protection (OVP) trip point
■ Enabling the overcurrent protection (OCP) circuit
■ Saving up to 5 operating states in nonvolatile memory
■ Recalling up to 5 operating states from nonvolatile memory
Note
You also can calibrate the power supply from the front panel (see Appendix
