is damaged, contact the Teledyne LeCroy service department immediately.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep the surface of the instrument clean and dry.
Avoid touching exposed circuits or wires. Do not touch exposed contacts
or components when the power is on.
Do not operate without covers. Do not operate the instrument with covers
or panels removed.
Use only the fuse specified for the instrument.
Use proper over voltage protection.
Use anti-static protection. Operate in an anti-static protected area. Ground
measurement cable conductors before connecting to the instrument to
discharge any static electricity before connecting the cables to the instrument.
Observe ventilation requirements. Ensure good ventilation. Check the
vent and fan regularly to prevent overheating.

1.1 General Inspection
Please check the instrument according to the following steps.
1. Inspect the shipping container.
Keep the shipping container and packaging material until the contents of the
shipment have been completely checked and the instrument has passed both
electrical and mechanical tests. It is always good practice to save the shipping
container and packaging for use when returning the power supply to Teledyne
LeCroy for service or calibration.
The consigner or carrier will be responsible for damage to the instrument
resulting from shipping. Teledyne LeCroy will not provide free maintenance or
replacement in this instance.
2. Inspect the instrument.
If the instrument is found to be damaged, defective or fails in electrical or
mechanical tests, please contact the Teledyne LeCroy service department
immediately.
3. Check the accessories.
Please check that you have received the accessories on the packing list. If the
accessories are incomplete or damaged, please contact Teledyne LeCroy
immediately.

1.2 Power and Electrical Check
To ensure that the power supply will work according to it’s specifications,
please conduct an inspection before using the instrument.
Input Power Requirement
The power supply requires 50Hz / 60Hz power line frequency, at any of four AC
voltage levels: 100V / 120V / 220V / 230V, ±10%. Select the required power
voltage level with the “DIP Switch” on the rear panel.
Warning
Set the required input power voltage “DIP Switches” before
connecting the power cord.
Electrical Check
Please use the power cord provided and adjust the DIP Switches to the local
AC line voltage, then connect the instrument to AC power.
1. Set the DIP Switches to the local AC power voltage.
2. Connect the power cord to the T3PS3000 before connecting the power
cord to wall socket.
3. Use a DMM to check the power cord ground pin is connected to the
T3PS3000 ground terminal, then attach the power cord to the wall socket.
4. Turn on the power switch.
5. Press the button POWER to enter the T3PS3000 power on sequence. The
T3PS3000 will run it’s power on self tests then return to the power on
default settings.
Warning
To avoid electric shock, please make sure that the instrument is
grounded correctly before powering on.

1.6 Output Check
The output check includes voltage check of all channels with no load, and current
check with a short circuit so as to make sure that the instrument is working
correctly.
Voltage Output Check
1. Within no load, turn on the power, and make sure the current setting
values of all channels are not zero.
2. Turn on CH1 and CH2 outputs, and check that the instrument is working
in constant voltage mode (CV on the display of each channel). Check
whether the output voltage value can be adjusted from 0V to 32V.
Current Output Check
1. Turn on the power, and make sure the current setting values of all
channels are not zero.
2. Use an insulated wire to connect the positive and negative terminal of
CH1/CH2.
3. Turn on CH1/CH2 and check that the instrument is working in
constant current mode. (CC on the display of each channel). Check
whether the current value could be adjusted from 0A to 3.2A.

2.1 Output Summary
The power supply has three independent outputs, two of which have adjustable
voltage or current values (depending on the operating mode) and the third having
selectable 2.5V, 3.3V or 5.0V output.
Independent / Parallel / Series
The power supply outputs of CH1 and CH2 have three output modes:
independent, parallel and series, which can be selected through the track switch
on the front panel. In the independent mode, the output current and voltage are
controlled independently for each channel. In the parallel mode, the current value
is twice that of the single channel. In the series mode, the voltage value is twice
that of the individual channels.
Constant Voltage / Current
In the constant current mode (independent or tracking mode), the current value
is set and controlled through the front panel. The output current will follow the
front panel, user set, output current level provided that the output voltage value
is less than it’s maximum preset voltage value. If less current is required by the
target system, then the output will switch to constant voltage mode, only
returning to constant current mode as the current demand rises to the
maximum preset current level.
In the constant voltage mode the voltage value is controlled through the front
panel. The output voltage will follow the front panel, user set, output voltage level
provided that the output current value is less than it’s maximum preset current
value. If more current is required by the target system, then the output will switch
to constant current mode, only returning to constant voltage mode as the current
demand falls below the maximum preset current level.

The Red line represents Voltage.
The Blue line represents Current.
The level between the two points represents the user preset maximum output
voltage level in this example.
The level between the two points represents the user preset maximum output
current level in this example.
At the beginning of the graph, “zero time”, the PSU is running in Constant Voltage
mode shown by the thick Red line tracking along the user present output voltage
line, Part A. The current is varying (due to load change) but is always below the
user present current threshold.
At time point the current has risen by the DUT current requirement, to reach
it’s user preset level. At this point the PSU automatically switches to Constant
Current mode whereby the current output will remain at the user preset level and
the voltage will fall according to the changing DUT load requirements, Part B.
If the DUT current requirement falls below the user preset current level then the
PSU will automatically switch back to Constant Voltage mode as show at point
12 Quick Start
Understanding Constant Voltage and Constant Current Modes

2.2 CH1 / CH2 Independent Output Mode
When CH1 and CH2 are working in independent mode, they each output their
set voltages and currents on their respective output terminals as shown below.
They are isolated from ground.
Output rating: 0~32V / 0~3.2A per channel for channels 1 and 2.
Operation
1. Make sure that parallel / series mode is off.
2. Connect the load to the positive and negative terminals of CH1 or CH2.
3. Set voltage and current value of CH1or CH2:
a) Press “1”/”2” button to select the wanted channel
b) Move the cursor through direction button to select the wanted parameter
(voltage, current).
c) Press “Fine” to select the digit position and then adjust the
multi-function knob to change the corresponding parameter.
4. Turn on the output: Press the “on/off” button to turn on the output, the
corresponding indicator light will illuminate immediately and “CC” or “CV” is
showed on the channel interface.
Quick Start 13

2.3 CH3 Independent Mode
CH3 is independent from CH1 and CH2, and it therefore does not work in
parallel or in series mode with CH1 or CH2. Its voltage and current ratings
can be set to any of the preset values of 2.5V, 3.3V, or 5V at up to 3.2A.
Output ratings: 2.5V / 3.3V / 5V at up to 3.2A.
Operation:
1. Connect the load to the positive and negative terminals of CH3 on the
front panel.
2. Select the wanted voltage value by moving the CH3 “DIP switch”.
3. Turn on the output: Press “on/off” button to turn on the output, the
corresponding indicator light is lit immediately.
When the current value is higher than 3.2A, the overload indicator light turns
red and the working mode turns to CC mode from CV mode.
Note: “Overload” does not indicate abnormal operation.
