Kunjalo:
- CQB75W8 75W ikota yezitini
Ukusetshenziswa kwamandla okungalayishwa okungu-10mA
Okokufaka okungu-3,000Vac kokuhlukaniswa kokukhishwa - CHB150W8 150W uhhafu wezitini
1,500Vdc okokufaka ekuhlukanisweni kokukhipha
"Bobabili banebanga lokufaka i-9V - 75Vdc, elibenza balungele yonke imithamo evamile yebhethri namabhasi kanye nezinhlelo ze-12V, 24V, 36V kanye ne-48V," ngokusho komhambisi we-Relec, okugcina ama-PSU. "Zifanele ukwakhiwa kwamandla kagesi okusatshalalisiwe, ezokuxhumana ngocingo, imishini esebenza ngamabhethri kanye nezicelo zezimboni, kanye nezicelo zezindawo ezifuna ujantshi".
Amandla wokwanda yi-100V yama-100ms, futhi izinketho zokukhipha yilezi: 12, 15, 24, 28 noma 48V (+ 15%, -20% adjustable).
Ukufaneleka ukuthola i-EN45545-2 umlilo nentuthu, i-EN 50155 (EN 61373) ukushaqeka nokudlidlizela ukusetshenziswa kwesitimela, i-UL62368-1 edition yesi-2 eqinisiwe, isitifiketi sokuhlola se-CB IEC62368-1, EN50155 / EN50121-3-2 (enamasekethe angaphandle) nokusebenza kuze kufike ku-5,000m.
“Ukwengezwa kwezingxenye zokuhlunga ze-EMC, kwenza abaguquli be-dc-dc bakwazi ukusetshenziswa ezinhlelweni zamasosha ezidingeka ukuhlangabezana ne-RTCA DO-160E, i-DEF STAN 6-15 ingxenye 6, iMil-STD-1275D neMil-STD-704A, ”Kusho uRelec.
Ukusebenza kahle kufinyelela kuma-90%, futhi ukusebenza kungenzeka ngecala eliphakathi kuka -40 ° C kanye no-105 ° C. Izikebhe zokushisa ezingakhethwa ziyatholakala ukunweba ibanga lokushisa elisebenzayo.
Ukuvulwa / ukuvalwa kwesilawuli kude (okuhle noma okubi) kufaka phakathi, futhi wonke amayunithi avikelwe nge-input under-voltage lock-out (i-UVLO nangokuphikisana: nokukhipha ngaphezulu kwamanje, okukhipha ngaphezu kwamandla kagesi, ukushisa ngokweqile kanye nokujikeleza okufishane okuqhubekayo.
Amakhasi womkhiqizo yile:
- CQB75W8 Uchungechunge
- Uchungechunge lwe-CHB150W8
IDorset-based Relec Electronics ingcweti ekuguqulweni kwamandla nakwimikhiqizo yokubonisa.
