1.4 Connecting the Device Under Test (DUT)

Precautions

This section describes how to connect the test cables between the instrument and DUT.

To prevent electric shock and damage to the instrument, observe the following precautions.

Inspection and Installation

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

• Before connecting test cables, be sure to switch off the instrument.

Power switch is in Off position, otherwise touching the output terminals on the rear panel may result in personal injury or death due to electric shock.

• To avoid electrical shock, before testing, please make sure the rating val-

ues of the testing cables, and do not measure the current that higher than the rating value. All test cables shall be capable of withstanding the maximum short circuit current of the instrument without causing overheat.

• If several loads are provided, each pair of load wires shall safely with-

stand the rated short circuit output current of the power supply under full load.

• Do not short the battery when connecting or disconnecting the battery

testing circuit. Short circuit may cause severe accident.

• Because the instrument can be used to sink current, hazardous voltages

from an external energy source such as a battery may be present on the output terminals even with the instrument power off. Provision must be made to disconnect the external energy source before touching the output or sense terminals.

• Always use test cables provided by ITECH to connect the equipment. If

test cables from other factories are used, please confirm the maximum current that the test cables can withstand.

• During wiring, check that the positive and negative poles of the test ca-

bles are properly and tightly connected. Do not connect the positive pole and disconnect the negative pole.

• Ensure that the output terminals are either insulated or covered using

the safety covers provided, so that no accidental contact with lethal voltages can occur.

Specification for Test Cables

Test cables are not standard accessories for the instrument. Please select op-

tional red and black test cables for individual sales based on the maximum current value. For specifications of test cables and maximum current values, refer to A.1 Appendix→Specifications of Red and Black Test Lines.

Connecting the DUT (Local Measurement)

The instrument supports two kinds of wiring methods with the DUT: local measurement and remote measurement (SENSE). The default test mode is local measurement.

The connection diagram and steps of local measurement are as follows:

Inspection and Installation

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

1. Confirm that the power switch is in the OFF position and verify that there is no dangerous voltage on the connection terminals.

2. Remove the output terminals cover of the power supply.

3. Loosen the screws of the output terminals and connect the red and black test cables to the output terminals. Re-tighten the screws.

When maximum current that one test cable can withstand fails to meet the rated current, use multiple pieces of red and black test cables. For example, the maximum current is 1,200A, then 4 pieces of 360A red and black cables are required.

4. Thread the red and black test cables through the output terminals cover of the power supply and install the cover.

5. (Optional) According to the actual situation of DUT, connect the grounding terminal on the rear panel of the instrument to the DUT to ensure the safe grounding.

For the location information, see 2.3 Rear Panel Introduction.

6. Connect the other end of the red and black cables to the DUT. The positive and negative poles must be properly connected and fastened when wiring.

Connecting the DUT (Remote Sensing)

Remote measurement is available for the following scenarios:

When the DUT consumes large current or the wires are too long, there is a voltage drop on the wires between DUT and output terminals of the power supply.

To maximize measurement accuracy, the power supply provides the remote measurement terminals VS+ and VS- on the rear panel, which can be used to measure the terminal voltage of the DUT.

When the power supply is used for battery testing in actual applications, the voltage drop of the wire will lead to voltage inconsistency of both ends and inconsistency of the cutoff voltage of power supply and the actual voltage of bat-

tery, resulting in inaccurate measurement.

The connection diagram and steps of remote measurement are as follows:

Inspection and Installation

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

1. Confirm that the power switch is in the OFF position and verify that there is no dangerous voltage on the connection terminals.

2. Refer to the wiring diagram and connect the Vs+ and Vs- with armored twisted-pair cables.

To ensure the stability of the system, use armored twisted-pair cables between the remote sense terminals and the DUT. Pay attention to the positive and negative poles when wiring, otherwise it will damage the instrument.

3. Remove the output terminals cover of the power supply.

4. Loosen the screws of the output terminals and connect the red and black test cables to the output terminals. Re-tighten the screws.

5. Thread the red and black test cables through the output terminals cover of the power supply and install the cover.

6. (Optional) According to the actual situation of DUT, connect the grounding terminal on the rear panel of the instrument to the DUT to ensure the safe grounding.

For the location information, see 2.3 Rear Panel Introduction.

7. Connect the other end of the remote sense cables to the DUT.

8. Connect the other end of the red and black cables to the DUT. The positive and negative poles must be properly connected and fastened when wiring.

9. Power on the instrument and turn on the Sense function of the instrument.

For details, see 3.6.3 Sense Function (Sense).

Never touch cables or connections immediately after turning off the instrument at the end of the test. Lethal voltages may remain at the output terminals after turn-off. Verify that there is no dangerous voltage on the output or sense terminals before touching them.

2.1 Brief Introduction

Quick Start

The IT6000C series Bi-directional Programmable DC Power Supply is designed with the module concept. The voltage class of each module is 80V/200V/360V/ 500V/800V. A single module can realize up to 800V/20A/6kW DC output capacity, and modules can be run in series or in parallel. At most of three modules can be connected in series or in parallel for a single unit (3U) with input of three-

phase 380V AC power supply. The 3U model on sales supports 500V/90A/ 18kW and 1500V/30A/18kW output to satisfy different test requirement such as high current and low voltage or high voltage and low current. Meanwhile, units can be run in parallel to deliver stronger output capacity.

In addition to the above powerful and diverse output capability, based on conventional features (such as List function, comprehensive protection and other

functions), the IT6000C series Bi-directional Programmable DC Power Supply also supports a variety of unique features, such as digital I/O, data logging, energy regeneration, and the selective upgrade of system files. More functions, technical indicators and technical innovations are described below:

• The standard 3U chassis of the IT6000C series instruments can accommo-

date up to 3 modules.

• Internal modules can be run in series or in parallel for voltage sharing or cur-

rent sharing.

• Single module output voltage ranges from 80V to 800V, and current ranges

from 20A to 170A.

• For the whole instrument, the output voltage ranges from 80V to 2250V, and

3.6.7 Digital I/O Function (Digital Port)

Basic Operation

The IT6000C series power supply supports digital I/O function. The user can realize logic control over high and low level input or output by related configurations in the system menu, namely general digital signal I/O function. In addition

to general digital I/O functions, this series can be customized to meet different special needs through different pin wirings. For example, you can connect a pin to an external instrument, and set a fixed pulse or level signal for the external instrument. Once the external instrument fails, output this pulse or level signal. After the instrument identifies this signal, it controls whether the power supply

output is reduced to 0 or whether the [On/Off] is switched off based on related settings.

The rear panel of the instrument has a green 8-pin terminal (For position, see

2.3 Rear Panel Introduction). The terminal is a wiring terminal with digital I/O

function. These pins are bi-directional I/O interfaces. For hardware index information, see Table 3–2 Hardware parameters of the I/O interface. The pins sup-

port the input or output of pulse and high and low level. Different pins can achieve different functions.

as Output, it can output the high level (False) or low level (True).

If the corresponding pin is configured as Invert, it means that the digital

signal is inverted and will output low level or high level.

• Under the default condition (Not-Invert), when the pin (1 to 7) is configured

as Output→PWM, the user needs to set the frequency (PWM Freq) and duty cycle (PWM Duty) values. For example, if the PWM Freq is set to 100Hz and the PWM Duty is set to 10%, the output waveform is as follows:

Basic Operation

In the above figure, the peak voltage (minimum value) is 5.16V and the

cycle is 10ms. The high level duration is 9ms and the low level duration is

1ms in one cycle.

• Under the default condition (Not-Invert), when the pin (1 to 7) is configured

as Input, it means the instrument can detect the level status of the external input. By default (i.e., the pin is not connected), it can be detected as high level, and the front panel will display input(0). If the pin is configured as

Invert, it can be detected as low level, and the front panel will display input (1).

4.4.1 Set the CC/CV Priority Mode

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

CV Priority

In CV priority mode, the output is controlled by a constant-voltage feedback loop, which maintains the output voltage at its programmed setting as long as the load current remains within the positive or negative current limit settings. CV

priority mode is best suited for use with resistive or high impedance loads, and loads that are sensitive to voltage overshoots. Do not use CV priority mode with low-impedance sources such as batteries, power supplies, or large charged capacitors.

In CV priority mode, the output voltage should be programmed to the desired

value. A positive and negative current limit value should also be set. The current limit should always be set to a value that is greater than the actual input current requirement of the external load. The following figure shows the CV priority operating locus of the output. The area in the white quadrants shows the output as a source (sourcing power). The area in the shaded quadrants shows the output as a load (sinking power).

Power Supply Function

The heavy solid line illustrates the locus of possible operating points as a func-

tion of output. As shown by the horizontal portion of the line, the output voltage remains regulated at its programmed setting as long as the load current remains within the positive or negative current limit setting. A CV status flag indicates that the output voltage is being regulated and the output current is within its limit settings.

Note that when the output current reaches either the positive or negative current

limit, the unit no longer operates in constant voltage mode and the output

CC Priority

Power Supply Function

voltage is no longer held constant. Instead, the unit will now regulate the output current at its current limit setting.

As shown by the vertical portions of the shaded quadrants, the output voltage may continue to increase in the positive direction or decrease in the negative di-

rection as current is forced into or pulled out of the unit. When the output voltage exceeds the over-voltage protection setting, the output will shut down.

In CC priority mode, the output is controlled by a bi-polar constant current feedback loop, which maintains the output source or sink current at its programmed setting. The output current remains at its programmed setting, provided the load voltage remains within the voltage limit setting. CC priority mode is best suited

for use with batteries, power supplies, large charged capacitors, and loads that are sensitive to current overshoots. It minimizes current overshoots during programming, turn-on, and turn-off transitions and seamlessly transitions between positive and negative currents.

In CC priority mode, the output current should be programmed to the desired

positive or negative value. A positive voltage limit range should also be set. The voltage upper limit should always be set to a value that is greater than the actual input voltage requirement of the external load. The following figure shows the CC priority operating locus of the output. The area in the white quadrants shows the output as a source (sourcing power). The area in the shaded quadrants shows the output as a load (sinking power).

The heavy solid line illustrates the locus of possible operating points as a function of output. As shown by the vertical portion of the line, the output current re-

mains regulated at its programmed setting as long as the output voltage

Power Supply Function

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

remains within its limit setting. A CC (constant current) status flag indicates that the output current is being regulated and the output voltage is within its limit settings.

Note that when the output voltage reaches the upper limit, the unit no longer op-

erates in constant current mode and the output current is no longer held constant. Instead, the unit will now regulate the output voltage at its voltage limit setting.

As shown by the horizontal portion of the shaded quadrants, when the unit is sinking power, the output current may continue to increase in the negative direction as more current is forced into the unit. This can happen when the instru-

ment is connected to an external device such as a battery, and its output voltage is higher than the voltage limit setting of the instrument. Once the current exceeds the built-in negative over-current limit, the output will shut down. In such a case, it is important to set the voltage limit properly in order prevent this protection shutdown.

Protection delay time, see Protection Delay.

Protection Delay

You can specify an OCP/OVP/OPP/UCP/UVP delay to prevent momentary output settings and status changes from tripping the protection. In most cases

these momentary conditions would not be considered an protection fault, and having an OCP/OVP/OPP/UCP/UVP condition disable the output when they occur would be a nuisance. Specifying an protection delay (Delay) can ignore these momentary changes during the specified delay period. Once the delay time has expired and the protection limit condition persists, the output will shut down.

Fault Prompt

When the instrument enters the protection state, the buzzer sounds (if Beep menu item is set as default state On), the VFD status indicators Prot and Off are lit, and [On/Off] is turned off.

Although [On/Off] is turned off, there may be dangerous voltage at the output electrodes. Do not touch the wiring cable or the electrode terminals.

When protection is generated, the VFD screen displays the following

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

information:

• The first row shows the meter voltage and the meter current value.

• The second row shows specific fault information, such as OVP.

Clear the Protection

After the instrument triggers protection and generates a fault message, you need to troubleshoot the possible cause. When the fault is resolved, the VFD will still prompt the fault information. You can manually clear the fault information record through the following methods.

• Input a pulse signal to pin 1 of the rear panel P-IO to clear the fault

information.

For details, see 3.6.7.1 IO–1. Ps-Clear, Not-Invert.

• Press the [Esc] or [Enter] key on the front panel to manually clear the fault

information.

Power Supply Function

• Connected to the host computer, the PC sends a PROTection:CLEar com-

mand to the instrument to clear the fault information.

After the protection fault is cleared, you need to press the [On/Off] key on the front panel or send the OUTPut ON command to the instrument to reopen [On/Off].

4.5.1 Set Over-Voltage Protection (OVP)

Users can enable the OVP function and set the protection limit Level and protection delay time Delay. When the voltage (i.e., the Meter value) is greater than this protection limit and the delay time is exceeded, the power supply will enter the OVP state.

Possible Cause

Many reasons can cause OVP, the details are as follows:

• The set protection limit Level is lower than the voltage Meter value.

• Input too high external voltage.

• The power supply outputs a high voltage due to a fault.

4.5.6 Over-Temperature Protection (OTP)

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

When internal temperature of instrument is higher than about 90 °C, the instrument is under temperature protection. At this time, the instrument will automati-

cally be OFF and VFD status indicator Prot lights up and the screen prompts

OTP.

Possible Cause

To prevent damaging heat build-up and ensure specified performance, make sure there is adequate ventilation and air flow around the instrument to ensure proper cooling. Do not cover the ventilation holes on the rear panel, sides, or

bottom of the instrument. Even with proper ventilation, the instrument can overheat in the following situations.

• If the ambient temperature is too high.

• If you use the instrument to test for long periods.

Power Supply Function

How to Set

The OTP limit does not need to be set, and the internal device of the instrument automatically detects and determines whether to enter the OTP state.

If an over-temperature condition occurs, power off the instrument and allow it to cool for at least 30 minutes. After the internal temperature of the instrument has cooled down, power it on again.

When you return power to the instrument, verify that the cooling fan is running. If not, please contact ITECH Technical Support. Leaving the

instrument powered on with an inoperative cooling fan may result in damage to the instrument.

4.5.7 Sense Reverse Protection

The instrument defaults to provide sense reverse protection. When the output

state is ON and the difference between output terminal voltage and sense remote voltage exceeds the specified voltage, sense reverse protection will be enabled after 500ms. The instrument output will be immediately switched to Off and the display screen will display Sense Reverse Prot if the sense terminals are reversed.

When the instrument is in Sense Reverse Protection state, you should check

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

whether the polarities are connected reversely or not firstly. If yes, you can reopen the output after the polarities connect correctly.

The voltage difference between output terminal and remote sense terminal of

each model is not the same. When the remote sense terminal is connected reversely, the maximum voltage will not exceed the sum of output terminal voltage and the difference voltage.
