ʻO 100W-150W ka mana o ka mana resistor i-247

To-247 mana pale o EAK no nā mea hoʻolālā hoʻolālā e hāʻawi i kahi pūʻolo transistor-type paʻa o nā mea pale ikaika kiʻekiʻe, ʻo 100W-150W ka mana.
Hoʻolālā ʻia kēia mau resistors no nā noi e koi ana i ka pololei a me ke kūpaʻa.Hoʻolālā ʻia ka resistor me kahi papa alumina ceramic e hoʻokaʻawale i ka mea pale mai ka pā kau.

Eak i hoʻoheheʻe ʻia iā TO-247 mānoanoa kiʻiʻoniʻoni mana pale
Hāʻawi kēia ʻano i ke kūpaʻa haʻahaʻa haʻahaʻa i ka wā e hōʻoiaʻiʻo ana i ke kūpaʻa insulation kiʻekiʻe ma waena o ka pahu a me ka mokulele metala.ʻO ka hopena, he haʻahaʻa loa ka inductance o kēia mau resistors, e kūpono iā lākou no nā noi pulse kiʻekiʻe a me ka wikiwiki.
ʻO ke kū'ēʻana mai ka 0.1Ω a hiki i ka 1 MΩ, Ke ana wela hana:-55°C a +175°C.
E hana pū ʻo EAK i nā mea hana ma mua o kēia mau kikoʻī e hoʻokō i nā koi o ka mea kūʻai aku.Hoʻokō nā mea pale mana EAK i nā kūlana ROHS, me ka hoʻopau ʻana i ke alakaʻi ʻole.
Nā hiʻohiʻona:
■ 100 W mana hana
■TO-247 hoʻonohonoho pūʻolo
■ Hoʻopaʻa maʻalahi ka hoʻopili ʻana i ka puʻu wela
■ Hoʻolālā non-inductive
■RoHS hoʻokō
■ Na mea e like me ka UL 94 V-0
M3 wili i kau i ka radiator.Hāʻawi ka pā i hoʻoheheʻe ʻia i ka pale a maʻalahi ke hoʻokomo.Hoʻolālā non-inductive, hale hoʻokaʻawale uila.
Noi:
■ Ke kū'ē hope i ka mana RF hoʻonui
■ Haʻahaʻa puʻupuʻu puʻupuʻu haʻahaʻa, pale pale ma ka mana lako
■UPS, buffers, voltage regulators, load and discharge resistors in CRT monitors

Alakaʻi noi no nā mea pale kiʻi Radiator Mounted Power
E ʻike i ka helu wela a me ka mana:

Kiʻi 1-e hoʻomaopopo i ka mahana a me ka helu mana
Huina o na mea lawe wela:
1, Aia kahi āpau ma muli o ka hoʻololi ʻana i ka ʻili male ma waena o ka pūʻolo resistor a me ka radiator.E hoʻemi nui kēia mau hakahaka i ka hana o nā mea hana TO-type.No laila, he mea koʻikoʻi ka hoʻohana ʻana i nā mea pili wela e hoʻopiha ai i kēia mau ea.Hiki ke hoʻohana ʻia kekahi mau mea e hōʻemi ai i ke kūpaʻa wela ma waena o kahi pale a me kahi ʻili radiator.
2, Heat-conducting silicone grease he hui ia o ka wela-conduct particles a me ka wai e hui ana e hana i ka like like me ka momona.ʻO kēia wai ka ʻaila silicone maʻamau, akā i kēia manawa aia kahi momona silicone conductive heat "Non-silicon" maikaʻi loa.Ua hoʻohana ʻia nā resins silicone thermally conductive no nā makahiki he nui a loaʻa i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa loa o nā lako thermally conductive i loaʻa.
3, Heat-conducting gaskets mea pani no ka wela-conducting silicone a loaʻa mai nā mea hana he nui.Loaʻa i kēia mau pads kahi ʻāpana a i ʻoki mua ʻia a ua hoʻolālā ʻia no nā ʻano ʻāpana maʻamau e like me TO-220 a me To-247.He mea spongy ka gasket conduction conduction, pono ke kaomi like a me ka hana paʻa e hiki ai ke hana maʻamau.
Ke koho ʻana i nā ʻāpana hāmeʻa:
He mea koʻikoʻi ka noʻonoʻo ʻana i ka ʻenehana kūpono i ka hoʻolālā hoʻoluʻu maikaʻi.Pono e hoʻomau ka paʻa ʻana i ka paʻa paʻa a me ke ʻano like ʻole o nā mea hana ma o ke kaʻa kaʻa wela me ka hoʻohuli ʻole i ka radiator a i ʻole nā ​​​​mea hana.
He nui nā mea hoʻolālā e makemake e hoʻopili i ka DeMint TO mana pale i ka radiator me ka hoʻohana ʻana i kahi puna puna ma kahi o kahi hui screw.Loaʻa kēia mau puna puna mai kekahi mau mea hana e hoʻolako ana i nā pūnāwai maʻamau a me nā radiators i hoʻolālā ʻia no ke kau ʻana i nā clip i loko o nā pūʻolo TO-220 a me To-247.He nui nā pōmaikaʻi o ka pūnāwai i maʻalahi e hōʻuluʻulu, akā ʻo kāna mea maikaʻi loa, ʻo ia ka hoʻohana mau ʻana i ka ikaika maikaʻi loa i waenakonu o ka mana pale (e nānā i ke Kiʻi 2)

ʻO ka Screw Mounting-belleville a i ʻole nā ​​​​mea holoi liʻiliʻi i hoʻohana ʻia me nā wili he ala kūpono e hoʻopili ai i ka radiator.ʻO nā mea holoi ʻo Belleville he mau mea holoi puna wai liʻiliʻi i hoʻolālā ʻia e mālama i ke kaomi mau ma luna o kahi ākea deflection.Hiki i nā Gaskets ke kū i nā pōʻai wela no ka wā lōʻihi me ka ʻole o ka hoʻololi kaomi.Hōʻike ke Kiʻi 3 i kekahi o nā hoʻonohonoho ʻenehana maʻamau no ka hoʻopili ʻana i ka pahu TO puolo i ka radiator.ʻAʻole pono e hoʻohana ʻia nā mea holoi maʻemaʻe, nā mea holoi hōkū, a me ka hapa nui o nā mea holoi laka ma kahi o nā mea holoi Belleville no ka mea ʻaʻole lākou e hāʻawi i ke kaomi mau a hiki ke hōʻino i ka pale.
Nā memo hui:
1, E hōʻalo i ka hoʻohana ʻana i nā mana mana TO series i nā hui SMT.
2, Pono e pale ʻia nā lako hoʻopili palaki e palupalu a kolo paha i nā mahana hana kiʻekiʻe
3, Mai hoʻopā i ke poʻo wili i ka pale.E hoʻohana i nā mea holoi maʻamau a i ʻole nā ​​mea holoi liʻiliʻi e puʻunaue like i ka ikaika
4, Hōʻalo i nā wili metala, kahi e ʻōwili ai i nā kihi o nā lua a hana i nā burrs luku i ka radiator.
5, ʻAʻole ʻōlelo ʻia nā Rivets.He paʻakikī ka hoʻohana ʻana i nā rivets e mālama i ke kaomi mau a hiki ke hōʻino maʻalahi i ka ʻeke plastik
6, Mai hoʻonui i ka torque.Inā paʻa loa ka wili, nahā paha ka pūʻolo ma ka ʻaoʻao loa o ka wili (ka hopena alakaʻi) a i ʻole e piʻo i luna.ʻAʻole ʻōlelo ʻia nā mea hana pneumatic.
