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 LSG Series 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 LSG Series.

To determine the voltage generated, the following equation can be used. E = L x (∆ I / ∆ T)

E= voltage generated L=load line inductance

1-4-5. Load Wiring

∆ 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.

Current

Voltage

time

∆I

∆T

Min. V

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.

“Twisted pair” will be shown on any connection

diagram where the load wires should be twisted together.

Description

The LSG Series 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

When connecting the LSG Series 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.

DUT

Electronic

Load

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.

Warning

Do not touch any of the input terminals when the unit is on.

Warning

Connecting the input terminals to the wrong polarity can damage the DUT or the LSG Series.

Warning

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.

1-4-6. Load Wire Connections

Description

The front panel input terminals feature polaritydistinct caps and accept M6 sized crimped terminals.

Caution

The front panel input terminals on the LSG Series are physically connected to the rear panel terminals.

Step

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 load wires to the input terminals:

 Connect the positive (+) input terminal on the

load generator to the high potential output of the DUT.

 Connect the negative (-) input terminal to the

low potential output of the DUT.

1-4-7. Using the Front Panel Input Terminals

Description

The rear panel input terminals accept up to M8sized crimped terminals. The rear terminals come with a load input terminal cover for safety.

Caution

The front panel input terminals on the LSG Series are physically connected to the rear panel terminals.

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 load wires to the input terminals:

 Connect the positive (+) input terminal on the

load generator to the high potential output of the DUT.

 Connect the negative (-) input terminal to the

low potential output of the DUT.

+ potentinal

- potential

Description

The rear panel terminal cover should be used to prevent electric shock. The rear panel terminal covers should always be used when connecting a load to the rear panel terminals. As the front panel and rear panel terminals are physically connected, the terminal cover should also be used as a safety measure when a DUT is connected to the front terminals

Caution

Ensure the power is off before making any connections to the LSG Series.

Note

In the following diagrams, the cable wiring is not shown for clarity.

1-4-8. Using the Rear Panel Input Terminals

1-4-9. Using the Terminal Cover(PEL -011)

1. Remove the screw holding the top cover to the

bottom cover.

2. Line-up the bottom cover with the notches in the

output terminals.

3. Place the top terminal cover over the bottom

cover.

Detail

4. Use your thumb to slide the terminal covers shut,

as shown in the diagram below.

5. When the top and bottom covers are flush,

reinsert the screw that was removed in step 1.

Description

The flexible rear panel terminal cover should be used when the load wiring becomes too thick to be used with the PEL-011 terminal cover. This is especially true when using the load generators in parallel. Like the PEL-013 terminal cover, the PEL-011 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.

1. Wrap the insulation sheets around the terminals and load cables, as shown below. Make sure the terminals and any exposed wires are covered by the sheets.

Insulation sheet

1-4-10. Using the Terminal Cover (PEL -013)

2. Secure the insulation sheets using the supplied velcro fasteners. 2 fasteners should be used for each sheet.

Fasteners

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.

Description

The LSG Series file system can save files to internal memory (Media | Memory) and external memory (Media | USB). To save or recall Memory, Setup or Preset data, the LSG Series uses a three tier system where files are saved or recalled in the following order: Active settings <> Internal memory <> USB. This can be best described in the picture below.

Local Memory

Media | Memory

Media | USB

Memory data

Setup data x1 Nseq. data x1

Fseq. data x1

Preset data x1

Memory data (M001 ~ M256)

Setup data (001 ~ 100)

Nseq. data x1 Fseq. data x1

Preset data (P0 ~ P9)

Active Settings

Memory data x1

For example: To load Preset Data P7 from USB, you must first load Preset Data P0~P9 to internal memory, then from internal memory load Preset P7 to be the active preset setting. For normal and fast sequences however, files can be saved or recalled directly to/from USB memory.

2-8. Save Recall

The LSG Series can save and recall system settings, preset data, memory data, Go-NoGo settings as well as normal and fast sequences to internal memory or to USB.

2-8-1. File Structure

Description

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

program chains.

 Program chains need not be executed in order.  There are 16 steps to a program.  There are up to 16 programs to a chain.

3-2. Program

The LSG Series 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.

The LSG Series 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.

Background

The OCP test function creates an automatic test to test the OCP of power supply products.

This test will test to see when the over current protection of a power supply is tripped and return the measurements for the voltage and current when the over current protection was tripped. The LSG also has a user-defined cutoff setting in the event that the power supply OCP fails.

The diagram below shows an example of the OCP Test Automation function:

3-3-8. Running a Fast Sequence

3-4. OCP TestAutomation

Example

The test current increases from a starting value (Start C) to an end value (End C). The current increases in steps (set by Step_C) with a set step

time (set by Step_T) until the power supply’s OCP

is tripped or the End C current level is reached.

Parameters

OCP. No

Selects one of 12 OCP test setup memories.

Range

High(CC Mode High), Mid(CC Mode

Middle) and Low(CC Mode Low)

Start Current (Start C)

Starting current value for the test.

End Current (End C)

The current value that will end the test. The value must be higher than the OCP value of the DUT you are testing. This parameter is used as a fail-safe for if the over current protection of the DUT fails. If the measured current is reaches End Current value it would then indicate that the power supply OCP failed.

Step Current (Step_C)

Sets the step resolution of the current.

Last Current (Last_C)

Sets the final current value after OCP has been tripped. This is the steadystate current draw after the OCP has been tripped.
