ET37 Series Programmable DC Lub Hwj chim Pab

Cov lus piav qhia luv luv:

ET37 series tawm linear DC fais fab mov yog wildly siv hauv R&D kuaj thiab tsim pov thawj, vim nws cov yam ntxwv xws li cov zis hluav taws xob muaj hluav taws xob zoo thiab lub suab qis. ET37 series cov phiaj xwm tso tawm kab hluav taws xob DC cov khoom siv hluav taws xob tau nruab nrog 4.3 "TFT xim xim screen, muaj lub ntsej muag ncaj thiab yooj yim, cov ntsiab lus nplua nuj thiab kev ua haujlwm yooj yim. Nws txaus siab rau qhov zoo xws li cov zis ruaj khov, tsis tshua muaj suab nrov, siab txhais, siab precision, thiab lwm yam. Muaj 4 tus qauv tsim tawm, muab cov khoom tsim tawm dav.

Tus neeg siv-phooj ywg tsim:

Kev siv 4.3 nti TFT LCD, qhov kev daws teeb meem yog 480 * 272.

¤ Txhawb waveform zaub, lub sijhawm pom tseeb ntawm cov zis hluav taws xob thiab qhov tam sim no nkhaus.

System Kev ua haujlwm zoo yog yooj yim thiab yooj yim, nrog kev siv khoom tsim teeb pom kev zoo hauv lub cev, yooj yim siv.

Muaj cov zis zoo:

Cov khoom tawm tau ywj pheej: 1 (ET372X) / 2 (ET373X) cov khoom tawm tau kho tau 30V / 3A (30V / 5A), 1 (2.5V / 3.3V / 5V)

adjustable tso zis ntau lawm; siab kawg tag nrho cov zog hluav taws xob tuaj yeem ncav cuag 305W.

Plaub tus qauv tawm tswv yim: ntsug / qhov zoo / tsis zoo / zoo tib yam / qauv, muab cov kev nthuav dav nthuav dav. Qhov tso zis ntau tshaj plaws

voltage tuaj yeem ncav cuag 60V, thiab qhov siab tshaj plaws tso zis tam sim no tuaj yeem ncav cuag 10A.

Precision High precision thiab cov siab daws teeb meem.

Output Tsawg cov zis ripple thiab lub suab nrov.

Nws muaj cov haujlwm zoo thauj khoom thiab tus nqi tso cai tswj tus nqi.

¤ Txhawb cov sij hawm ua kom tawm ua haujlwm, qhov siab tshaj plaws teev cia 112 pawg.

Nws muaj txoj haujlwm ua haujlwm ntawm kev cia khoom thiab caw, thiab tuaj yeem txuag tau li 10 pawg ntawm qhov chaw teeb tsa.

Standardized USB Device interface, RS232 interface, txhawb SCPI chaw taws teeb tswj chaw.

Ntau qhov kev tiv thaiv kev ruaj ntseg:

¤ Nrog dhau-voltage / dhau-tam sim no tiv thaiv muaj nuj nqi, nws muaj peev xwm hloov qhov yooj yim dhau-voltage thiab dhau-tam sim no rau

cuag tau kev tiv thaiv zoo load.

Nws muaj ob-theem tshaj-kub tiv thaiv kev ua haujlwm, paub qhov tseeb tshaj ob-kub tiv thaiv software thiab

kho vajtse.

Nws muaj txoj haujlwm ua haujlwm ntawm kev tswj hwm lub kiv cua kom nrawm, kho lub kiv cua kom ceev raws li kev ua haujlwm, thiab

zoo txo cov ntxuam suab nrov.

Txuas thiab Kev Tawm Tsam-tiv thaiv nrog Output Polarity.

Nws muaj qhov yuam sij ntsuas phoo kom tiv thaiv kev ua tsis tiav.
