Parameter:
Example:
POW:PROT:UND
This command sets an under power protection limit to the input power that the Electronic Load accepts. When the input
power falls below the under power protection limit for the programmed dela y period, the load input is off.
Parameter:
Example:
POW:PROT:UNDER:DEL
This command sets the delay time for under-power protection. When the input power falls below the programmed power
limit for the programmed delay period, the Electronic Load input is off.
Parameter:
Example:
POW:TRIG
This command sets the input voltage level that is to be applied on occurrence of a trigger in the constant power mode. If
the Electronic Load is not in the CP mode when the command is sent, the programmed TRIG level becomes a stored
IMM level that takes effect when the Load changes to CP mode. The rate of input change is in accord with the slew rate
in effect.
Parameter:
Example:
POW:TLEV
This command sets the transient voltage level in C P mode. When the transient subsystem is on, the Electronic Load will
switch between the main level and transient level at a rate determined by the slew rate in effect. If the programmed
transient power level is below the main voltage level, the switching will not occur until the main level is belo w the value
of POW:TLEV. The IEEE488.1 command, "PTR" can also be used.
Parameter:
Example:
POW:SLEW
This command sets the power slew rate in CP mode. The pro grammed slew rate is in effect for all voltage changes except
INP:ON or OFF. The hardware implementation selects a slew rate that is closest to the POW:SLEW value. To determine
the actual value, use the query POW:SLEW?.
Parameter:
Example:
POW:DUTY
This command sets pulse duty cycle, as a percentage of the total cycle, of continuous transient mode in CP mode. If the
Electronic Load is operating in another mode, the duty cycle is stored until the Load changes to continuous mode.
Parameter:
Example:
POW:FREQ
This command sets pulse frequency of continuous transient mode in Hz. If the Electronic Load is operating in another
mode, the pulse frequency is stored until the Load changes to continuous mode.
Parameter:
Example:
POW:LIM:MAX
This command sets and queries the maximum input power level that is to be applied immediately in the constant power
mode.
