Load current slew rate setting

What is the load current slew rate during load current level change, power supply turn ON/OFF
switch between ON, and OFF? The 34000A series Electronic load provides all of the above load
current slew rate in controllable condition, the rise and fall current slew rate can be set
independently from front panel operation or remote programming.
The slew rate determines a rate at which the current changes to a new programmed value. The
slew rate can be set at the front panel or via GPIB on the rear panel of 34000A Series high power
load.
The rise and fall slew rate can be independently programmed from 256mA/usec to 16A/usec
(34210A Load) in the 320A current range and from 25.6mA/usec to 1.6A/usec in the 32A current
range. This allows a independent controlled transition from Low load current level to High load
current level ( Rise current slew rate ) or from High load current level to Low load current level( Fall
current slew rate ) to minimize induced voltage
induced transients on the est. device ( power supply transient response testing ).
This controllable load current slew rate feature also can eliminate the overload current Phenomenon
And emulate the actual load current slew rate at turn ON the power supply Under test.
Fig 2-8 shows the load current slew rate is according to the power supply's Output Voltage,
Load level setting and Load ON/OFF switch. So, you could do all items of Power Supply testing
Task by using Constant current mode only, it can significantly improve The Testing quality and
Process as well as efficiency.
There are two load current range in 34000A Series Load, Range I and Range II, the slew rate of
range I, range II, RISE/FALL slew rate are listed in chapter 1-4 specifications.
