DESIGN FEATURES

Steady state operating mode

The T3EL15030xP features four operating modes

toprovideflexibletestcapabilities.InCCmode,the

electronicloadwillsinkaconstantcurrent,regardlessof

thevoltageatitsterminals.InCVmode,theelectronic

load will cause a constant voltage to appear at its

terminals.InCRmode,theelectronicloadwillbehave

asaﬁxedresistancevalue.Asshownintheﬁgure,the

electronic load will linearly change the current according

totheinputvoltage.InCPmode,theelectronicloadwill

causeaconstantpowertobedissipatedintheload.

Dynamic test mode up to 25 kHz (CC)

Thetransienttestallowsswitchingbetweentwodifferent

loadvalues.Acommonapplicationistotestthedynamic

characteristicsofaDCsourceorDUT(DeviceUnder

Test).Thetransienttestfunctionenablestheloadto

periodicallyswitchbetweentwosetlevels(LevelAand

LevelB).Thehighestfrequencycanbesetto25kHzin

CCmode.Thehighestfrequencycanbesetto12.5kHz

inCPmodes.

4-wire SENSE compensation mode function

InCC/CV/CR/CWmode,whenaloadisconnectedtoa

powersupply,itwillcausealargevoltage-droponthecon-

nectionlinesbetweentestedinstrumentandterminalsof

load.Usingremotesense,youcanmeasurethevoltageat

theDUTsinputterminals,effectivelyremovingtheaddi-

tional error due to the voltage drop in the connection wires.

Simplify complex sequencing using the

list operation function

Youcangeneratecomplexloadsequencesquicklyusing

thelistoperationfunction.Here,youcanedittheset-

points,dwelltime,andslewrateforeachstepinthetest.

*SlewratecanonlybeeditedinCCmode.

DESIGN FEATURES

Program function

Inprogram(auto-test)mode,youcangenerate

asequenceoftestsusingdifferentmodes,mode

parameters and durations. This function is useful for

automatically executing a set of tests on a device then

display whether the tests passed or failed. Test results

areeasilyviewedbypressingtheupanddownbuttons.

The load provides 8 nonvolatile registers to save auto-

testﬁleforrecalllater.Eachﬁlecontains1–50steps

tosetup.Auto-testfunctionisespeciallyusefulinthe

designingbatterychargingcircuitry.

OCPT/OPPT Mode

Over-current protection (OCPT) mode prevents drawing too

muchcurrentfromtheDUT.Aftertheinputvoltagereaches

theVonpoint,theDCloadwillstarttodrawacurrentfrom

the source after a delay time. The current value will increase

byacertainstepsizeatregularintervals.Simultaneously,

the DC load will compare the input voltage to the OCP

voltage:Ifitislower,thenthepresentcurrentvaluewillbe

compared to see if it is in the current range you have set.

Withintherange,theOCPtestwillevaluatePassorFail.

Ifitisoutsideofthesetrange,theDCloadwilltoincrease

drawing current and compare the voltage again.

CR-LED Mode

TheT3EL15030xPincludesaCR-LEDmodespeciﬁcally

forLEDdrivertesting.BasingonthetraditionalCRmode,

CR-LEDmodeaddsadiodebreak-overvoltagesetting.

Whentheinputvoltageisabovethissetvalue,the

DCloadstarttowork.Thus,itcanemulatetheactual

characteristics of an LED.

Battery discharge function

TheT3EL15030xPcanalsoprovideinsightintobattery

performancebyanalyzingthedischargecharacteristics

oftheDUT.TheT3EL15030xPfeaturesthreestop

conditionsforthedischargetest:Voltage,capacityor

time. The discharge process is immediately terminated

if the stop conditions are met. This provides more

control over the test termination and an extra layer of

safety during critical tests. Throughout the test process

thebatteryvoltage,dischargecurrent,dischargetime

anddischargedcapabilityisdisplayedclearlyonthe

LCDpanel.

Overpower-protection (OPPT) mode: When the input

voltagehasreachedtheVonpoint,theloadwilldraw

power after a delay time. The power value will increase

byastepsizeatregularintervals.Simultaneously,the

DCloadwilljudgewhethertheinputvoltageislowerthan

OPPvoltageyouhaveset,ifitis,thenthepresentcurrent

valuewillbecomparedtoseeifitisinthecurrentrange

youhaveset.Withintherange,theOPPtestwillPassor

Fail.Ifitisoutsideofthesetpower,theloadwillcontinue

to increase the power draw within the cut-off current

range and compare OPP voltage with the input.

External analog control

The load allows the user to control current or voltage

through external analog terminals (EXT PRG). Input

a0–10Vanalogtoadjust0–100%ratedvoltageand

current. It is very useful for those applications that need

to change the input value with external signals.

Multiple protection modes

TheT3EL15030xPseriesProgrammableDCElectronic

Loadprovidesﬁveprotectiontypes:OVP,OCP,OPP,OTP

and LRV. When OVP/OCP/OPP/OTP/reverse voltage

protection(LRV)occurs,theloadwillimmediatelyturn

offtheinputandstopsinking.Then,apromptmessage

is displayed.

Voltage Rise/Fall speed test

Theelectronicloadisalsoequippedtodirectlymeasure

voltage rise and fall times. It can calculate the time from

one voltage to another without the need for additional

measurementinstrumentation.WithanT3EL15030xP,

youcansavemoneyandimproveefﬁciency.

Waveform trend chart function

The electronic load includes a waveform display function

and supports the following operations for the waveform:

Pause,recording,andcapturingthewaveform.Youcan

quicklyobservethetrendsofparameterchangesasthey

occur throughout the test.

Voltage threshold function

TheT3EL15030xPcanbesettoturnonoroffiftheinput

voltageisat,above,orbelowasetvalue.Bydeﬁningthese

thresholds,youcontrolwhentheloadisactive.Which

minimizes test time and increases safety.

Save/Recall setting parameters

Theloadallowsyoutosavedifferenttypesofﬁlestothe

internal and external memories. You can recall and read

them when necessary.
