Ọkụ ọkụ (PSUs) na-eje ozi dị ka ọkpụkpụ azụ arụ ọrụ nke sistemu nchekwa eletrọnịkị, na-agba mbọ na-aga n'ihu, ike kwụsiri ike na ihe ndị dị mkpa. Nrụ ọrụ teknụzụ ha ruru:

Ngwa isi:

1. Igwefoto onyunyo (IP/Analog): Na-enye ntụgharị voltaji 12VDC/24VAC ziri ezi, na-ewepụ mkpọtụ ihe onyonyo/flicker. PoE (Power-over-Ethernet) switches na-ejikọta ọrụ PSU iji nyefee data + ike n'elu otu eriri.

Sistemụ Njikwa Nweta: Na-akwado mkpọchi eletrọnịkị, ndị na-agụ kaadị, na ihe nyocha biometric nwere voltaji a na-achịkwa iji gbochie ịjụ/anabata ụgha.

3. Ihe mmetụta nchọpụta intrusion: Na-ejigide 12VDC mgbe niile maka ihe nchọpụta ngagharị nke PIR, ihe mmetụta nkwụsịtụ iko, yana kọntaktị ọnụ ụzọ/ime windo.Ihe mmetụta nchọpụta ntrusion: Na-ejigide 12VDC mgbe niile maka ihe nchọpụta ngagharị nke PIR, ihe mmetụta nkwụsịtụ iko, yana kọntaktị ọnụ ụzọ/ime windo.

4.Control Panel/NVRs: Na-enye ike ụgbọ oloko dị iche iche (dịka, 5VDC maka bọọdụ mgbagha, 12VDC maka draịva nchekwa) yana nchebe ịwa ahụ.

Ọrụ nka nka:

1.Voltaji ụkpụrụ: Ụdị mgbanwe PSU na-atụgharị AC mains ka ọ bụrụ obere mkpọtụ DC site na mgbanwe mgbanwe dị elu na MOSFET, na-ejigide ± 3% voltaji ndidi n'agbanyeghị mgbanwe ntinye.

2. Mgbochi Ripple: Nzacha dị elu (netwọk LC + seramiiki capacitors) na-ebelata mpụta mpụta ruo

3. nkwado ndabere: Na-atụgharị na-akpaghị aka na batrị lead-acid/Li-ion mechiri emechi n'oge mwepu site na sekit njikwa batrị (BMS), na-akwado sistemụ maka awa 24-72.

4. Environmental hardden: PSU-ọkwa ụlọ ọrụ na-arụ ọrụ na -40°C ruo +85°C nwere mkpuchi conformal iji guzogide iru mmiri/uzuzu.

Akụkụ dị mkpa nchekwa-kpọmkwem:

1. Oge nkwụsị efu: Ọtụtụ PSU na-ekpo ọkụ na-ekpo ọkụ na sistemụ ụlọ ọrụ na-ewepụ otu isi ihe ọdịda.

2.Intelligent nlekota oru: Digital PSU na-akọ metrics ozugbo (ibu%, temp, ahụike batrị) site na SNMP/RS-485 gaa na nyiwe VMS.

3. Oti mkpu: Relays kọntaktị akọrọ na-arụ ọrụ ma ọ bụrụ na batrị AC dara ma ọ bụ dị ala, na-ebute ọkwa.

4.Surge/Spike Nchekwa: Multi-stage TVS diodes na gas na-agbapụta tubes na-egbochi 6kV+ transients site na àmụmà/EMI.

Mmetụta:

Enweghị PSU arụpụtara nke ọma, sistemụ nchekwa na-eche isi ihe ọdịda dị egwu ihu. Atụmatụ ọgbara ọhụrụ na-arụ ọrụ> 90% arụmọrụ (80 Plus Gold) ka ọ na-ahụ na ọdịda millisecond-larịrị, na-eme ka usoro "mgbe niile" dị mkpa maka ngwa nchekwa ndụ. Njikwa okpomọkụ (aluminom heatsinks + ikuku mmanye) na-egbochi ịgba ọsọ na-ekpo ọkụ n'oge ọrụ nkwado ogologo oge, na-eme ka PSU bụrụ onye nlekọta na-enweghị atụ nke iguzosi ike n'ezi ihe.
