Wire Gauge
considerations
Before connecting the unit to a power source,
the wire gauge must be taken into account.
Load wires must be large enough to resist
overheating when a short-circuit condition
occurs as well as to maintain a good
regulation. The size, polarity and length of a
wire are all factors in determining if a wire
will withstand short circuiting.

When using the PEL-3000E load generator,
voltage drop and voltage generated due to
load line inductance and current change must
be taken into account. Extreme changes in
voltage may exceed the minimum or
maximum voltage limits. Exceeding the
maximum voltage limit may damage the PEL3000E.
To determine the voltage generated, the
following equation can be used.
E = L x (∆ I / ∆ T)
E= voltage generated
L=load line inductance
∆ I= change of current (A)
∆ T= time (us)
Load line inductance (L) can be approximated
as 1uH per 1 meter of wire. (∆ I / ∆ T) is the
22
GETTING STARTED
slew rate in A/us.
Limiting Load line
inductance
The diagram above shows how changes in current
can affect voltage.
Load line inductance can be reduced in two
ways.
1. Ensure load wires are as short as possible
and twist the positive and negative load wires
together.
2. Current change can be limited by limiting
the slew rate speed when switching in CR and
CC mode.
“Twisted pair” will be shown on any
connection diagram where the load wires
should be twisted together.

Follow the procedures below for the load
connection. Please adhere to the following
precautions to ensure your safety and to
protect the unit from damage.
When connecting the PEL-3000E to the DUT,
make sure that the polarity of the connection
between the DUT and the unit matches.
Ensure that the maximum input voltage is not
exceeded. The maximum input voltage is 150
volts (PEL-3031E).
If the polarity to the input terminals is reversed,
the reverse voltage protection function is tripped.

Remote Sense
PEL-3000E Series User Manual
Description
Steps
Remote sense can be used to help compensate
for long cable length. The longer the cable, the
higher the potential resistance and inductance,
therefore a short cable is best. Twisting the
cable can help reduce induced inductance and
using the Vsense terminals compensates the
voltage drop seen across the load leads,
especially leads with higher resistance. This is
useful when used in CV, CR or CP mode.
1. Turn the power off from the rear panel or put
the unit into standby mode.
2. Turn the power off from the DUT.
3. Connect the DUT to the load terminals, see
page 21, 24.
4. Connect the sense wires to the sense terminals:
Connect the positive sense (+S) terminal to the
high potential output of the DUT.
Connect the negative sense (-S) terminal to the
low potential output of the DUT.

Warning
Firmware Update
Description
System version
Operation
1. Press
Ensure that the load is connected to the DUT
before connecting the sense wires. If only the
sense wires are connected to the DUT, the load
will be seen at the sense terminals. This will result
in an internal fuse entering a high-impedance
state due to over temperature. At this point, any
measured values will be erroneous. You must wait
for the temperature to return to normal operating
temperature before the unit should be used again.
The PEL-3000E allows the firmware to be
updated by end-users. Before using the PEL3000E, please check the GW Instek website or
ask your local distributor for the latest
firmware.
Before updating the firmware, please check

Description
The PEL-3000E has two switching modes,
static and dynamic. The switching modes
allow the PEL-3000E to switch between two
preset levels. Static mode can only switch
between the two levels manually, while
Dynamic mode switches between each level
automatically based on a timer.
Static mode: A Value, B Value
Dynamic mode: Level1, Level2
When the unit is set to static mode, only one
value (A Value or B Value) can be active at a

Program
The PEL-3000E can create programs that are designed to stepthrough up to 16 pre-set load operations. The program function is a
powerful tool that can allow you to perform a number of different
operations in succession.
The execution time of each step is user-defined.
Programs can be chained together to make larger programs.
Up to 16 programs can be created for a program chain.
See page 112 for saving load operations.
Program Overview
Description
84
When you run a program, you are essentially
executing up to 16 different load operations
consecutively. Each of the different load
operations are “steps” in the program. A
program starts at step 01 and ends at step 16.
A program recalls the operating mode, range,
static/dynamic mode, response speed and
other settings of each step from stored memory.
It also recalls the Go-NoGo settings.
The same memory settings can be used for
multiple steps.
The execution time of each step is configurable.
Applies the Go-NoGo settings for each step.
Each step must be executed in order.
Each step can be configured to automatically go
to the next step or wait for confirmation from
the user before proceeding to the next step.
Individual steps can be skipped.
Programs can be linked together to make

OPERATION
Sequence
The PEL-3000E supports both programs and sequences. The
essential difference between programs and sequences is that
programs can use different operating modes for each step while
sequences use the same operating mode throughout the whole
sequence. In effect sequences are used to create complex load
simulations.
There are two different types of Sequences, Normal Sequences and
Fast Sequences.
Normal sequences can define the execution time and slew rate of
each step.
On the other hand the execution time for each step in a fast
sequence is fixed to the rate (Time Base setting) set by the user.
Normal Sequence Overview
Description
A normal sequence is comprised of a userdefined number of steps that when executed in
sequence can be used to simulate a DC load.
Up to 1000 discrete steps can be configured
using normal sequences.
Each normal sequence can have a memo note
attached to it.
Normal Sequences can be looped up to 9999
discrete times or for an infinite amount of
times.
Normal sequences can be configured to hold a
set voltage, current, power or resistance at the
end of the load.
Normal Sequences can be linked together in a
chain.
