Taw qhia

Nws siv rau kev txiav txim siab Planck qhov tsis tu ncua yog siv los ua lub txiaj ntsig photoelectric, Lub tshuab lim tau txais cov qib siab ua tiav ua haujlwm ntau ntxiv thiab tsim cov qauv hluav taws xob tshwj xeeb, kev tsim kho lub raj xa hluav taws xob zoo, thiab lub xov tooj hu ua lub lim dej nrog cov qauv tshiab thiab ua tiav txoj haujlwm.

Photocell rhiab ≥ 1mA / LM, tsaus nti tam sim no ≤ 10A; xoom xaim ≤ 0.2% (kev nyeem tag nrho, 10a iav, tom qab 20 feeb ntawm kev ntsuas lub sijhawm, ntsuas tsis dhau 30 feeb nyob rau hauv ib puag ncig ib puag ncig); 3.5-nti LED tso saib, cov zaub hluav taws xob tsawg kawg nkaus yog 10a, qhov ntsuas hluav taws xob tsawg kawg nkaus yog 1mV, yog li "xoom tam sim no" lossis "txoj kev them nqi" tuaj yeem siv los ntsuas qhov txiav tawm qhov hluav taws xob
