Ko te raupapa HWM021 he pūngao hiko hohe toru-wāhanga DIN railmitas. He maha ngā hangarau matatau e whakamahia ana e rātou mō te rangahau me te whanaketanga, pērā i ngā tikanga hiko-iti, te hangarau IC tauine nui motuhake (porowhita whakauru), te hangarau tukatuka me te tauira mamati, te tikanga SMT, me ētahi atu. Ko ā rātou mahi hangarau e tino rite ana ki ngā Paerewa o te Ao IEC 62053-21 mō te kaha hohe wāhanga-toru o te Akomanga 1.mitaKa taea e rātou te ine tika me te tika i te whakapaunga kaha o te kawenga i roto i ngā whatunga AC e toru-wāhanga o te auau whakatauranga 50Hz, 60Hz rānei. He maha ngā momo kōwhiringa o te raupapa HWM021, kia rite ki ngā tono rerekē o te mākete. He āhuatanga pai, he pono hoki mō te wā roa, he iti te rahinga, he māmā te taumaha, he āhua tino pai, he ngāwari te tāuta, me ētahi atu.

Ngā mahi me ngā āhuatanga

◆ 3 Kei te wātea hei rēra paerewa DIN 35mm e mau ana, e rite ana ki ngā Paerewa DIN EN 50022, me te PANEL o mua e mau ana (ko te tawhiti waenga i waenga i ngā kōhao e rua he 63mm).

◆ He kōwhiringa mā te kaiwhakamahi ngā tikanga tāuta e rua i runga ake nei.

◆ Whānui o te pou 10 (tauwehenga 12.5mm). e tutuki ana i ngā Paerewa JB/T7121-1993.

◆ Ka taea te tīpako i te rēhita nekehanga motuka hiko o ngā mati 6 (99999kWh) mati 6+1 rānei (999999. 1kWh) te whakaaturanga LCD rānei.

◆ Ka taea te whiriwhiri i te tauranga whakawhitiwhiti raraunga ā-roto o te infrared tawhiti me te tauranga whakawhitiwhiti raraunga RS485. E tutuki ana te kawa whakawhitiwhiti ki ngā Paerewa DL/T645-1997. Ka taea hoki te whiriwhiri i tētahi atu kawa whakawhitiwhiti.

◆ Ka taea te tīpako i te pākahiko lithium kore tiaki i roto mō te whakaaturanga LCD hei pānui i te mita i te wā e motuhia ana te hiko.

◆ E rua ngā momo hononga o te hononga-S (waea tomo mai i raro me te waea putanga i runga): te hononga tika me te hononga CT hei kōwhiringa. Mō te hononga CT, e 27 ngā momo reiti CT hei whakarite, i muri i te whakarite CT, ka taea e tātou te pānui tika i te mita, kāore e hiahiatia te whakarea i ngā reiti CT.

◆ Ko te mita hononga CT he 7 mati whakaatu LCD: 5+2 mati (ko te tere CT anake he 5:5A) 7 rānei

ngā tauoti, e whakawhirinaki ana ki te tautuhinga o te reiti CT.

◆ He taputapu whakaputa hiko pūngao korekore e rite ana ki ngā Paerewa IEC 62053-31 me te DIN 43864.

◆ Ka tohu motuhake ngā rama LED i te āhua mana o ia wāhanga, te tohu hiko me te āhua whakawhitiwhiti raraunga.

Ka kitea aunoa te ahunga rere o te ia o te kawenga, ā, ka tohua e te rama LED.

◆ Inehia te whakapaunga pūngao hohe i te taha kotahi i runga i te wāhanga e toru, kāore e pā ana ki te ahunga rere o te iahiko kawenga, kia rite ki ngā Paerewa IEC 62053-21.

◆ He mea hanga te taupoki poto o te pito ki te PC mārama, hei whakaiti i te wāhi tāutanga, ā, he watea hoki mō te tāutanga pokapū.
