Ang System Settings ay naglalaman ng backlight, sound, RS-232\/network, at factory-default restore.

Ang 5-digit voltage \/ 4-digit current readout ay tumutugma sa setting resolution end-to-end kaya ang ipinapakitang halaga ay ang mismong programmed value, hindi isang rounded approximation.\u003c\/p\u003e\n\u003ch3\u003eLinear Topology \u0026lt; 350 µVrms Output Ripple\u003c\/h3\u003e\n\u003cp\u003eLinear pass-element regulation, hindi switching converter — ang output ripple ay nananatili sa ilalim ng 350 µVrms (5 Hz–1 MHz) at 2 mVpp peak-to-peak. Ang line at load regulation ay nananatili sa loob ng 0.01% + 2 mV. Para sa low-noise analog work, sensor-bridge excitation, ADC reference rails, at anumang measurement na malapit sa noise floor nito, ang linear topology ang pagkakaiba sa pagitan ng malinis na signal at paghabol sa mga supply artifact. Ang transient response na mas mababa sa 50 µs ay kayang humawak ng real load steps; ang 10 ms command processing time ay nagpapanatili sa pagiging responsive ng automated sweeps.\u003c\/p\u003e\n\u003ch3\u003eReal-Time Voltage \/ Current \/ Power Waveform Display\u003c\/h3\u003e\n\u003cp\u003eAng 4.3-inch TFT LCD ay nagpapakita ng boltahe, kuryente, at power waveforms sa real time sa lahat ng configured channels — bawat channel, nang sabay-sabay. Ang mga inrush event, load steps, at power-up transients ay makikita mismo sa display ng supply, hindi kailangan ng oscilloscope para sa routine na pagmamasid sa power-behavior. Ang mga set\/limit value para sa boltahe, kuryente, OVP, at OCP ay lumalabas lahat sa tabi ng live readouts kaya ang configuration at ang aktwal na output ay nananatili sa isang screen.\u003c\/p\u003e\n\u003ch3\u003eList Output at Delayer Functions\u003c\/h3\u003e\n\u003cp\u003eAng list function ay bumubuo ng programmable na boltahe at kuryente waveforms na may hanggang 10 stored list profiles kada supply. Ang mga built-in template (sine, ramp, pulse) ay nagpapabilis ng setup; binibigyang-daan ka ng editor na malayang tukuyin ang waveform points, dwell intervals, voltage\/current limits, at inversion. Ang delayer function ay nagdaragdag ng programmable on\/off sequencing — kapaki-pakinabang para sa power-on\/off reliability testing, sequenced rail bring-up, at stress cycling.

Ang falling-edge \/ rising-edge triggering at selectable response (output toggle, output on, output off) ay sumasaklaw sa mga karaniwang automation pattern nang direkta nang hindi kailangan ng karagdagang sequencer.\u003c\/p\u003e\n\u003ch3\u003eSCPI sa pamamagitan ng LAN, RS-232, USB — at Web Server Browser Control\u003c\/h3\u003e\n\u003cp\u003eAng SCPI command control ay tumatakbo sa LAN, RS-232, at USB-Host. Ang built-in Web Server ay nagdaragdag ng browser-based remote control: anumang laptop o workstation sa parehong subnet ang nagpapatakbo ng front panel sa pamamagitan ng web page — walang driver install, walang application. Kasama ang kasamang PC software, ang UDP3305S ay madaling maisasama sa mga existing automated test environment at naglilingkod sa mga remote-bench scenario kung saan ang rack-mount supply ay hindi pisikal na naa-access. Ang Digital I\/O ay nagdaragdag ng hardware trigger lines para sa mas mahigpit na timing coordination kaysa sa software loops lamang.\u003c\/p\u003e\n\u003ch3\u003eOVP \/ OCP \/ OTP na may Configurable Monitor Conditions\u003c\/h3\u003e\n\u003cp\u003eAng per-channel over-voltage protection, over-current protection, at over-temperature protection ay nagbabantay sa device under test. Binibigyang-daan ng Monitor function ang malayang configuration ng protection trigger condition (V upper limit, I upper limit, P upper limit, na may logical OR combination) at ang tugon — output off, warning beeper, o pareho. Ang voltage at current limit functions ang nagtatakda ng adjustable range para sa mga guarded teaching-lab o operator-supervised configuration.

Ang lahat ng apat na channel ay ganap na isolated sa isa't isa — ikonekta ang mga ground kung saan mo kailangan, hayaan silang floating kung hinihingi ng test.

Ang numeric keypad ay direktang nagtatakda ng mga value nang hindi na kailangang maghalungkat sa menu; ang rotary encoder ay nag-a-adjust nang pino kapag mas mabilis ang maliit na adjustment kaysa sa pag-type. Ang mga soft-key ay tumutugma sa function na kasalukuyang ginagamit — list mode, slope, OVP\/OCP, o DVM — sa halip na itago ang mga ito sa malalalim na menu. Ang output enable ay isang nakalaang hardware button, laging nakikita, at hindi madaling mapindot nang hindi sinasadya.\u003c\/p\u003e\n\u003ch2\u003eRemote Sense\u003c\/h2\u003e\n\u003cp\u003eAng mahahabang test lead ay nagdudulot ng pagbaba ng voltage.

Ang UDP6900 series ay itinatama ito gamit ang four-wire remote sense: ikonekta ang \u003cstrong\u003e+\u003c\/strong\u003e at \u003cstrong\u003e−\u003c\/strong\u003e terminals ng output sa load sa pamamagitan ng current-carrying leads, pagkatapos ay gumamit ng hiwalay na pares mula sa \u003cstrong\u003eS+\u003c\/strong\u003e at \u003cstrong\u003eS−\u003c\/strong\u003e nang direkta sa device na sinusuri.

Kapag tumama ang alinman sa limitasyon, pinuputol ng supply ang output at ipinapakita ang trigger sa LCD — ang uri ng malinaw na fault state na mahalaga kapag ang pagkabigo ng DUT habang ginagawa ang characterization sa magdamag ay maaaring makapinsala sa hardware o makawala ng test run. Ang mga threshold ay nananatili sa kabila ng power cycles at nananatiling aktibo kahit naka-lock ang front panel para sa unattended operation.\u003c\/p\u003e\n\u003ch2\u003eList Output and Delay Function\u003c\/h2\u003e\n\u003cp\u003eAng list mode ay nagpo-program ng hanggang 512 na grupo ng voltage\/current\/time, na isinasagawa nang sunud-sunod — kapaki-pakinabang sa 25 A continuous para sa characterization ng low-voltage inverter input-stage (pagdaan sa 12 V, 24 V, at 48 V system levels sa full current draw), para sa high-current DC-DC converter input sweeps, at para sa controlled-current battery discharge profiles. Ang delay function ay nagpo-program ng on\/off sequencing ng output para sa load-cycling reliability tests. Ang mga file ay sine-save sa Flash o USB sa mga format na \u003ccode\u003e.lst.csv\u003c\/code\u003e at \u003ccode\u003e.dly.csv\u003c\/code\u003e — na maaaring i-edit sa Excel.\u003c\/p\u003e\n\u003ch2\u003eSlope Mode Options\u003c\/h2\u003e\n\u003cp\u003eSa 25 A continuous, ang hindi kontroladong pagtaas ng agos (current rise) sa isang inductive o low-impedance load ay isang tunay na panganib. Tatlong slope mode ang pumipigil dito. Ang Normal mode ay direktang tumatalon sa set value. Ang Voltage Slope (VSR) ay nag-a-ramp ng voltage sa configurable na bilis. Ang Current Slope (ISR) ay nag-a-ramp ng current nang step-by-step — kritikal para sa mga motor-drive bench setup, low-voltage inverter input stages, at anumang DUT kung saan ang startup di\/dt ay nagtatakda kung gagana ba o mabibigo ang DUT sa SOA gate.\u003c\/p\u003e\n\u003ch2\u003eAuto Range Functionality\u003c\/h2\u003e\n\u003cp\u003e600 W ng working envelope, na may output reconfiguration sa buong V\/I plane ayon sa pangangailangan: 60 V sa 10 A para sa high-side characterization, 25 A sa 24 V para sa low-voltage inverter input stages, o anupaman sa pagitan nito. Sa 25 A continuous, ang UDP6952B ay humahawak ng mga current range na hindi kayang abutin ng mga fixed supply sa 100–200 W class — nang hindi nagsasakripisyo ng upper voltage kapag kailangan ito sa bench.\u003c\/p\u003e\n\u003ch2\u003eBuilt-in Digital Voltmeter (DVM)\u003c\/h2\u003e\n\u003cp\u003eAng built-in na 4½-digit voltmeter ay sumusukat ng DC voltage sa isang hiwalay na pares sa rear-panel, na ipinapakita kasama ng sariling readbacks ng supply sa LCD. Para sa two-rail bench scenario — ang pagsukat ng regulated DC ng load habang nagbibigay ng supply ang unit — ang DVM ay nag-aalis ng pangangailangan para sa pangalawang instrumento. Ang range ay 0.001–65.000 V sa 60 V models, hanggang 160 V sa UDP6933B at UDP6953B.\u003c\/p\u003e\n\u003ch2\u003eMultiple Main Menu Options\u003c\/h2\u003e\n\u003cp\u003eAng istruktura ng main menu ay sadyang mababaw.

Ipinapakita ng Monitor ang live na V\/I\/P\/DVM na may mga alarm bawat channel kapag lumihis ang set conditions. Ang Output Settings ay nag-aayos ng operating mode, power-up output, at slope. Ang System Settings ay naglalaman ng backlight, sound, RS-232\/network, at factory-default restore. Ang hierarchy ng menu ay hindi kailanman lumalagpas sa dalawang antas — nakakaabala sa trabaho ang masyadong malalim na menu, at ang UDP6900 ay hindi humihingi sa operator na isaulo ang mga tree.\u003c\/p\u003e\n\u003ch2\u003eComputer Software and Remote Control\u003c\/h2\u003e\n\u003cp\u003eAng UDP6900 series ay may kasamang libreng PC control software — ang UNI-T UDP9000 host application, na karaniwan sa buong programmable PSU line. Itakda ang voltage at current nang malayuan, mag-log ng readbacks sa disk, mag-sequence ng list at delay programs, at mag-automate ng kumpletong characterization runs nang hindi sumusulat ng SCPI parser. Para sa mga scripted environment, ang supply ay natively na gumagamit ng SCPI, Multi-SCPI, at Modbus RTU sa pamamagitan ng USB-Device, RS-232, RS-485, o LAN — piliin ang bus na angkop sa iyong test station.\u003c\/p\u003e\n\u003ch2\u003eMulti-Machine Communication\u003c\/h2\u003e\n\u003cp\u003eAng RS-485 networking ay nag-uugnay ng maraming UDP6900 supply sa isang host.

Ang multi-machine communication sa pamamagitan ng RS-485 ay nagbibigay-daan sa master\/slave configuration — ikonekta ang mga yunit nang series para sa mas mataas na boltahe o parallel para sa mas mataas na kuryente, na kinokontrol mula sa isang master o sa pamamagitan ng SCPI command.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-question\"\u003eAno ang kasama sa UDP6922B?\u003c\/h3\u003e\n\u003cp\u003eAng UDP6922B ay ipinapadala kasama ang instrumento, power cable.
