PS：DC Voltage limit also is related to Voltage Level range. Maximum DC limit voltage at
300V range is ±424.2V , and is ±212.1V at 150V outpt range.

3.5.2 I Limit, OCP Delay

I Limit represents Current Limit, it is used to set the maximum output current (rms). Its
range is related to Voltage Level setting：
Voltage Level
300V
150V
OCP Delay represents Over Current Protection (OCP) Delay Time, it is the delay time to
shut down output voltage after output current reaches OCP point. Its range is between 0~5
seconds, resolution is 0.1second. Both I Limit and OCP Delay are controlled by FW instead
of by HW.
Operation of OCP Delay Time：When output current (rms) measurement is over I Limit
parameter, OCP delay time start to count. If OCP last t seconds, then：
 t > OCP Delay parameter  Output shuts down. Screen shows "Software OCP".
 t < OCP Delay parameter  Output continues, no protections or reports.
