Operation
Power Supply Operation
OVP The over voltage protection level is set with a command for remote mode and with the front panel potentiometer for local mode. If operating in remote mode, and the OVP is disabled by setting the trip level to 0, a second hardware OVP circuit, fixed at approximately 115%, may trip and shutdown the unit. If this occurs, either shutdown the unit, or toggle the output with a command, the interlock or front panel S/D button to clear the OVP circuit.
OVP operation will remain the same for local mode. Specifically, it will be controlled via the front panel potentiometer. The OVP LED will indicate if OVP has been tripped. Either pressing the S/D button, or asserting the interlock will clear the OVP condition and the unit resumes normal operation when the respective signal is removed.
Fold Fold Mode protection will shut the power supply down when the unit enters the Protection selected regulation mode for a specified period of time.
A programmable delay time causes the supply to wait before shutting down the output.
To set the fold mode:
OUTP:PROT:FOLD {CCCVNONE}
Where:
•NONE indicates fold protection is disabled.
•CC indicates the supply will shut down due to constant current condition.
•CV indicates the supply will shut down due to constant voltage.
The default value is NONE.
To set the fold delay:
OUTP:PROT:FOLD:DEL <delay_time>
Where:
<delay_time> is a value in the range of
Units may be specified as “ms” (milliseconds) “s” (seconds), or “min” (minutes). If no units are specified, the default seconds are assumed. (Increments of 0.1s are allowed.) The default value is 0.5 second.
