Isitjengiso se-LED

Okuluhlaza: isibonisi samandla

Isikhathi sokuphendula

2ms ukufikelela ku-90% wenani lokugcina

Ukutjhuguluka kwamazinga womtjhiso

0.005% FS/°C

Amapharamitha womtjhiso

Izinga lokutjhisa lokusebenza: -20°C ~ +60°C,
Izinga lokutjhisa lokugcina: -40°C ~ +80°C

Umswakama ohlobene

10%~95% RH akukho ukutjhisa

Amandla wokuvikela

Phakathi kwehlangothi eliphephileko nelingaphephileko (≥3000VAC/min); hlangana nokuphakelwa kwamandla nehlangothi elingaphephiko (≥1500VAC/min)

Ukujamelana nokuvikela

≥100MΩ (phakathi kokufaka/ukukhipha/ukuphakelwa kwamandla)

Ukukhambisana kwe-elekthromagnethi

Ngokuya nge-IEC 61326-1 (GB/T 18268), i-IEC 61326-3-1

MTBF

100000h

Iimfuneko zeentambo

Isigaba esiphambanweni ≥ 0.5mm2; Amandla wokuvikela ≥ 500V

Iinsetjenziswa ezisebenzako

Isiginali yomtjhini weentambo ezimbili, ezintathu (i-HART) nofana umthombo wamanje (i-HART)

Indawo yokufaka

Indawo yokufaka: Ifakwe endaweni ephephileko, ingahlanganiswa namathulusi wokuphepha wangaphakathi eendaweni eziyingozi ukuya ku-Zone 0, IIC, Zone 20, kanye ne-IIIC
