conductive pollution occurs. Occasionally,
however, a temporary conductivity caused by
condensation must be expected.

 Pollution degree 3: Conductive pollution

occurs, or dry, non-conductive pollution occurs
which becomes conductive due to condensation
which is expected. In such conditions,
equipment is normally protected against
exposure to direct sunlight, precipitation, and
full wind pressure, but neither temperature nor
humidity is controlled.

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.

Wires that are selected must be large enough to
withstand a short circuit and limit voltage drops
to no more than 2V per wire. Use the table below
to help make a suitable selection.

Load Line
Inductance
Considerations

When using the PEL-3000(H) 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 PEL-3000(H).

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 slew rate

in A/us.

The diagram above shows how changes in current
can affect voltage.

Limiting Load line
inductance

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 or response speed when switching in
CR and CC mode.

Description

The PEL-3000(H) has input terminals on both the
front and rear panels.

Follow the procedures below for all load
connections. Please adhere to the following
precautions to ensure your safety and to protect
the unit from damage.

Connection

1. When connecting the PEL-3000(H) to the DUT,

make sure that the polarity of the connection
between the DUT and the unit matches.

2. Ensure that the maximum input voltage is not

exceeded. The maximum input voltage is
150(800) volts.

Caution

If the polarity to the input terminals is reversed, the
reverse voltage protection function is tripped. The
reverse voltage protection function is tripped when
reverse voltages greater than -0.3V are detected.

Do not touch any of the input terminals when the
voltage is applied to an input terminal.

Connecting the input terminals to the wrong polarity
can damage the DUT or the PEL-3000(H).

The front panel and rear panel input terminals are
physically connected. Any voltage that is input to one
set of terminals will also appear on the other set of
terminals.

especially true when using the load generators in
parallel. Like the PEL-013 terminal cover, the PEL­011 is used to prevent electric shock. The rear
panel terminal covers should always be used
when connecting a load to the rear panel
terminals.

Caution

Ensure the power is off before making any
connections to the booster pack.

Remote Sense

Description

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.

Steps

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 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.

Step Resolution Configuration

There are two different ways to set the resolution when using the
scroll wheel to edit parameters. Step Mode and Cursor Mode. Step
Mode is the default method. Only one mode can be active at a time;
When one mode is active, the other mode is deactivated.

Cursor Mode Configuration

OPERATION

Description

When set to Step Mode, the voltage, current,
resistance and power settings can have the step
resolution configured. The step resolution refers to
the step resolution of the coarse adjustment for
these settings. The fine adjustment cannot be
configured.

See the Conventions section on page 45 for details
on how to switch between coarse and fine
adjustment modes.

Settings

The step resolution of each setting is configured
separately for each current range.
