PLZ-3W/3WH Series - Kikusui Electronics Corp.

System Electronic LoadsPLZ-3W/3WHSeriesThree-memory function andswitching functionIndividual set values can be stored inthree memories [A], [B], and [C] and canbe recalled freely. For the C.C and C.Rmodes, the instruments have a switchingfunction that recalls these values from thememories in the order [A], [B], [C], [A],[B], [C], .... and executes them repeatedly.Switching waveform (in C.Cmode)H: 5 ms/div, V: 10A/divMemory A 0 A, 12 msMemory B 30 A, 10 msMemory C 59 A, 15 msSoft-start function that suppressesoutput voltage distortionThe start-up time of the instruments canbe changed in accordance with theoutput-voltage rise time for the devicebeing tested. This allows them toconduct tests which more closely approximatereal-world conditions.(Soft-start time: Selectable from 0.1, 1, 2,5, 10, 20, 50, and 100 ms)Note: In case of PLZ-3WH series,selectable from 0.5ms.DC power supply start-up timeElectronic load start-up timeShort-circuit function that allowsinstantaneous setting of the maximumcurrentDuring operations in C.C or C.R mode,pressing the SHORT key allows you toset either the maximum current value (inC.C mode) or minimum resistance value(in C.R mode) of the range instantaneously,without using the JOG orSHUTTLE key. In addition, when alarge-current relay or other element isconnected to the external control connectoras shown below, if the voltage at theload terminals falls below approximately1.5 V, the load terminals will be in ashort-circuit state. This allows theinstruments to perform effectively atcurrents of 1.5 V or less during currentlimitingdrooping characteristic tests ofDC power supplies.Device being tested+_Large-current relay+_PLZ-3W/3WHSeriesBufferTo Meet More ExpandingApplicationsParallel operations that offerincreased current and powercapacitiesThe PLZ-3W/3WH Series allow parallelconnection of identical models in order toincrease current and power capacities. Inparallel operations, a single master unitcan control multiple slaves, such assetting total current for all. Naturally, thetotal current is also displayed on themonitors. A maximum of five instrumentscan be operated in parallel.ModelRated capacities in parallel operationsFor 2 units For 3 units For 4 units For 5 unitsPLZ153W300W, 450W, 600W, 750W,60A 90A 120A 150APLZ303W600W, 900W, 1200W, 1500W,120A 180A 240A 300APLZ603W1200W, 1800W, 2400W, 3000W,240A 360A 480A 600APLZ1003W2000W, 3000W, 4000W, 5000W,400A 600A 800A 1000APLZ153WH300W, 450W, 600W, 750W,15A 22.5A 30A 37.5APLZ303WH600W, 900W, 1200W, 1500W,30A 45A 60A 75APLZ603WH1200W, 1800W, 2400W, 3000W,60A 90A 120A 150APLZ1003WH2000W, 3000W, 4000W, 5000W,100A 150A 200A 250ATimeExample where soft-start is not usedTimeExample where soft-start is used5

System Electronic LoadsPLZ-3W/3WHSeriesApplicationsActual-load simulationsThe actual-load simulations used of sequencefunction can be conducted by taking the realwaveform data into the P.C.Capturing Data:The load current of a motor is captured using anoscilloscope, and the waveform data is saved in thebuilt-in memory of the PLZ-3W/3WH through theGPIB interface.Calling the data:As the data stored in the built-in memory is availableeven when the GPIB interface is disconnected,you can do actual-load simulations in test lines orwithout integrating a complicated system.Automatic test system for DC currentCombining the PLZ-3W/3WH Series with aKikusui PCR-L Series AC power supply allows youto configure an automatic test system for switchingpower supplies.AC input side test ...
