2.4 Transient Operation
When the transient operation is enabled, the load periodically switch between two levels (LevelH
and LevelL), which can be applied to test the dynamic characteristics of the power supply. The
transient operation can be executed in the CC, CV and CR modes, and has three operating statuses:
Continuous, Pulsed, and Toggled. Please make sure the List Operation has been disabled before
enabling transient operation.
The parameters associated with transient operation are: low level (LevelL), high level (LevelH),
low level time (TimeL), high level time (TimeH), time for rising edge (TimeR), time for falling edge
(TimeF), and operating mode.
Transient high/low level and corresponding CC, CV and CR modes share the same setting ranges.
The range for high/low level time is 0 ~ 655.35ms; the range for rising/falling edge time is 10us ~
655.35ms; the time resolution is 10us, and the maximum test frequency is 50kHz.
Transient test can be turned on and off via
key at the front panel or via remote command
(TRANsient ON/OFF). Before you turn on transient test, you should set the load to the operating mode
that needs transient test.
Note: In transient test, the Von point and current limit should be taken into consideration, which
may cause the shut down of the input, thus interrupt the transient test.
2.4.1 Continuous Transient Operation
In continuous operation, the load periodically switches between high/low levels, and this
operation is not affected by the trigger signal The relevant parameters such as low level (LevelL), high
level (LevelH), low level time (TimeL), high level time (TimeH), time for rising edge (TimeR), time
for falling edge (TimeF), and continuous transient operation can be set through transient operation
menu or via remote command (CURRent:LLEVel <NRf+>, CURRent:HLEVel <NRf+>,
VOLTage:LLEVel <NRf+>, VOLTage:HLEVel <NRf+>, RESistance:LLEVel <NRf+>,
RESistance:HLEVel <NRf+>, TRANsient:LTIMe <NRf+>, TRANsient:HTIMe <NRf+>,
TRANsient:RTIMe <NRf+>, TRANsient:FTIMe <NRf+>, TRANsient:MODE CONTinuous).
For example: assume that the CCH range is active, and the input is in OFF status, then the
transient parameters should be set as follows:
Press
key to enter into transient operation;
Press
key to open transient operation menu;
Set the following parameters in transient operation menu:
LevelL: 5.000A
LevelH : 10.000A
TimeL : 0.50ms
TimeH : 0.50ms
TimeR : 0.20ms
TimeF : 0.20ms
Mode : Cont
