5 – Front Panel Operation
Set transient operation for Pulse mode
In this example, assume that the CC mode is active, the slew rate is at the factory default setting (maximum
rate), and the applicable transient operation parameters have been set as follows: pulse mode, main current level
= 5 A, transient current level = 10 A, pulse width = 1 millisecond.
In this example, the electronic load starts conduction at the main current level setting (5 amps). When the
transient mode is turned on and an external trigger signal is received, module input current will slew to and
remain at 10 A for the remainder of the 10 millisecond time period, then slew to and remain at 5 A until another
trigger is received. Any triggers that occur during the time the transient level is in effect will extend the pulse
by another 10 milliseconds. Figure 5-6 shows the waveform that would result in this pulsed transient example.

Set transient operation for Toggled mode
In this example, assume that the CC mode is active, the slew rate is at the factory default setting (maximum
rate), and the applicable transient operation parameters have been set as follows: toggle mode, main current
level = 5 A, transient current level = 10 A.
The operation of toggled mode is similar to that described for continuous and pulse operation, except that each
time a trigger is received the input alternates between the main and transient current levels. Figure 5-7 shows the
waveform that would result for this toggled transient operation example
