When using the power supply in the United Kingdom, make sure
the power cord meets the following safety instructions.

As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:

The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol

or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment
or contact the supplier.

This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.

Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

The bleed resistance can be turned on or off using

On the T3PS, the internal resistance of the power
supply can be user-defined in software. (Internal
Resistance Setting, see the Normal Function
Settings on page 82.) When the internal resistance
is set it can be seen as a resistance in series with
the positive output terminal. This allows the

Fan failure. This alarm function is activated when
the fan RPMs drop to an abnormally low level.

Force Shutdown is not activated as a result of the
T3PS series detecting an error. It is a function that
is used to turn the output off through the
application of a signal from the rear-panel analog
control connector when an abnormal condition
occurs.

Alarms are output via the analog control
connector. The alarm output is an isolated open­collector photo coupler output.

The following situations should be taken into consideration when
using the power supply.

When the power supply switch is first turned on,
an inrush current is generated. Ensure there is
enough power available for the power supply
when first turned on, especially if a number of
units are turned on at the same time.

When the load has current peaks or is pulsed, it is
possible for the maximum current to exceed the
mean current value. The T3PS power supply
ammeter only indicates mean current values,
which means for pulsed current loads, the actual

loads, the current limit must be increased, or a
power supply with a greater capacity must be
chosen. As shown below, a pulsed load may
exceed the current limit and the indicated current

When the power supply is connected to a
regenerative load such as a transformer or
inverter, reverse current will feed back to the
power supply. The T3PS power supply cannot
absorb reverse current. For loads that create
reverse current, connect a r
power supply to bypass the reverse current. This
description only applies when the bleed resist
is off.

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

When the power supply is connected to a load

such as a battery, reverse current may flow back to

the power supply. To prevent damage to the
power supply, use a reverse-current-protection
diode in series between the power supply and
load.

T3PS

The output terminals of the T3PS power supplies are isolated with
respect to the protective grounding terminal. The insulation
capacity of the load, the load cables and other connected devices
must be taken into consideration when connected to the protective
ground or when floating.

As the output terminals are floating, the load and
all load cables must have an insulation capacity
that is greater than the isolation voltage of the
power supply.

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

If the positive or negative terminal is connected to
the protective ground terminal, the insulation
capacity needed for the load and load cables is
greatly reduced. The insulation capacity only
needs to be greater than the maximum output
voltage of the power supply with respect to
ground.

Before operating the power supply, please see the Getting Started
chapter, page 10.

The OVP level and OCP level has a selectable
range that is based on the output voltage and
output current, respectively. The OVP and OCP
level is set to the highest level by default. The
actual selectable OVP and OCP range depends on
the T3PS model.

When one of the protection measures are on, ALM
indicator is lit red on the front panel and the type
of alarm is also shown on the display. The
ALM_CLR button can be used to clear any
protection functions that have been tripped. By
default, the output will turn off when the OVP or
OCP protection levels are tripped.

The UVL will prevent you from setting a voltage
that is less than the UVL setting. The UVL setting
range is from 0%-105% of the rated output voltage.

When using local sense, the sensing terminals are connected to the
local sense terminals (via the local sense connections) and thus do
not compensate for any possible voltage drop that is seen on the
load cables. Local sense is only recommended when the voltage
drop is of no consequence or for load-current applications. By
default, the sense plug is already configured to local sensing.

Remote sense is used to compensate for the voltage drop seen
across load cables due to the resistance inherent in the load cables.
The remote sense terminals are connected to the load terminals of
the DUT to determine the voltage drop across the load cables.

Remote sense can compensate up to 1 volt (T3PS062001P), 2 volts
(T3PS40381P), 3 volts (T3PS60251P). Load cables should be chosen
with a voltage drop less than the compensation voltage.

Although you can use remote sense to compensate up to 3V for a
single line, it is recommended that the voltage drop is minimized to
a maximum of 1V to prevent excessive output power consumption
from the power supply and poor dynamic response to load changes.

This section describes the basic operations required to operate the
power supply in series or parallel. Operating the T3PS series in
parallel increases the total current output of the power supply units.
When used in series, the total output voltage of the power supplies
can be increased.

When the units are used in parallel or in series, a number of
precautions and limitations apply. Please read the following
sections before operating the power supplies in parallel or series.

When connecting the T3PS power supplies in
parallel, up to 4 units can be used in parallel and
all units must be of the same model with similar
output settings.

To use the power supplies in parallel, units must
be used in a aster-slave configuration. In the
master-

power supplies. In order for the master unit to
control the slave units, the master unit must use
the analog control connector to control the slave
units.

When using the Analog Control Connector, the
connector must be wired correctly between the
master and each of the slave units. For the
complete connector pin assignment, see page 98.

For 2 units in parallel, the internal resistance is
actually half of the setting value.

For 3 units in parallel, the internal resistance is
actually a third of the setting value.
For 4 units in parallel, the internal resistance is
actually a fourth of the setting value.
See function setting F-08 for internal resistance
settings, page 84.

Bleeder Control

The Master unit is used to control the bleeder
settings. The bleeder resistors in all the slave
units are always turned off when in parallel

Trigger Input/Output Configuration Settings and Special Function
Settings. Power ON Configuration differs from the other settings in
that the settings used with Power ON Configuration settings can
only be set during power up. The other configuration settings can
be changed when the unit is already on. This prevents some
important configuration parameters from being changed
inadvertently. Power On Configuration settings are numbered F-90
