電源選型推薦 整個DTU系統(tǒng)的電源解決方案，主要考慮到不間斷供電的問題，所以需要雙電源供電的一個供電形式，主流的供電方式一般是有兩部分組成，一部分是大功率300W或者500W的AC/DC充電電源，這個電源一般兩路輸出，一路給后級的板卡進行供電，一方面給后級的蓄電池或者是超級電容進行充電；另外的一部分就是蓄電池或者超級電容，這個主要是在市電斷電的情況下，保證整個系統(tǒng)的正常運行。另外，電網(wǎng)對于EMC方面的要求比較苛刻，特別是浪涌方面，需要完全滿足4級的要求。主電源和蓄電池都掉電時，系統(tǒng)掉電保持時間500mS以上。 根據(jù)上面的應(yīng)用描述，我們推薦選用金升陽MBP500-2A54D54的接線式電源，它具備電池充電功能，可對48V 鉛酸電池充電；工業(yè)級工作溫度：-40℃～+70℃；2500VAC 高隔離電壓；大瞬時過功率達540W；優(yōu)越的EMC性能；接線式安裝。 另外，如果鉛酸電池的電壓值為24V，還可以選用金升陽公司的MBP300-2A27D27的接線式電源，可對24V的鉛酸電池充電，穩(wěn)態(tài)功率達到351W。 電源是各種電子設(shè)備必不可缺的組成部分,其性能優(yōu)劣直接關(guān)系到電子設(shè)備的技術(shù)指標(biāo)及能否安全可靠地工作。目前常用的直流穩(wěn)壓電源按功率管的工作方式分為線性電源和開關(guān)電源兩大類。線性穩(wěn)壓電源亦稱串聯(lián)調(diào)整式穩(wěn)壓電源,電路技術(shù)比較成熟。具有低紋波、高穩(wěn)壓性能等優(yōu)點。但由于必須使用工頻變壓器,且調(diào)整管工作在線性放大區(qū),因而體積大和重量大、效率低。開關(guān)電源調(diào)整管工作在高頻開關(guān)狀態(tài),功率損耗小,且使用小體積的高頻變壓器替代笨重的工頻變壓器來實現(xiàn)電壓變換和電網(wǎng)隔離。 為解決傳統(tǒng)的PWM型變換器的上述問題,可采用諧振、準(zhǔn)諧振、多諧振以及具軟開關(guān)的PWM型變換器。這些變換器吸收、利用了PWM型變換器中的寄生參數(shù)或外加電感、電容作為諧振參數(shù),使變換器中的功率開關(guān)在零電壓或零電流下開通和關(guān)斷,開關(guān)兩端的電壓或經(jīng)過開關(guān)的電流是正弦或半正弦波形。因此大大減少開關(guān)的瞬問損耗和開關(guān)應(yīng)力以及電磁干擾和射頻干擾.使其工作頻率可進一步提高到1Mhz以上，效率達90%以上。再加上小型片狀電子元器件,包括磁性材科,例如:平板型變壓器等以及表面安裝技術(shù)以及散熱方式的改進，就使電源系列、標(biāo)準(zhǔn)化、模塊化成為現(xiàn)實。 New Honeywell R7847A1033 R7847 A 1033 Burner Controller #50 Honeywell Measurex Edge Det Processor 05311400 Rev C *NEW* HONEYWELL 621-1180RC 115 VAC INPUT 60 DAY WARRANTY! *NEW* HONEYWELL 621-1180RC 115 VAC INPUT 60 DAY WARRANTY! ~ Honeywell Screw Terminal Block Excel 800 Controller XSU821-22 NIB EC4-3 ~ Honeywell Screw Terminal Block Excel 800 Controller XSU821-22 NIB EC4-3 ?Yamatake Honeywell AZBIL J-DIM00 /??DHL shipping 1 PC Honeywell 621-9939-C Link Module for Series 9000 In Good Condition 1 PC Honeywell XCL5010 Controller Module In Good Condition 1 PC Honeywell 621-9939-C Link Module for Series 9000 In Good Condition 1 PC Honeywell XCL5010 Controller Module In Good Condition 1 PC New Honeywell DN65 ball valve B5011C0065 1 PC New Honeywell R4343E1014 Relay Flame Detecto In Box 1 PC New Honeywell R7849 A 1015 1 PC New Honeywell R7861 A 1026 Self Check Ultraviolet Flame Amplifier In Box 1 PC New Honeywell Voyager 1400G 2D Area-Imaging Scanner 1 PC Used Honeywell 621-9939-C Link Module for Series 9000 In Good Condition 1 PC Used Honeywell XCL5010 Controller Module In Good Condition 1 pcs Honeywell L404F1102 pressure controller 1 pcs HONEYWELL LSXA3K-1A Limit switch 1 pcs HONEYWELL CP-WM-VAV control panel 1 PCS Honeywell HC900 DCS 900P01-0001 Tested 1 pcs HONEYWEL BXA3K-1A Explosion-proof limit switch 1 pcs honeywell 129464N Ultraviolet phototube 1 pcs honeywell R7861A1026 Protection relay 1 pcs honeywell V5011P1038 1 pcs honeywell 129464N Ultraviolet phototube 1 pcs honeywell C7035A1023 Flame Sensor 1 pcs honeywell C7035A1023 Flame Sensor 1 pcs HONEYWELL CP-WM-VAV control panel 1 PCS Honeywell HC900 DCS 900C53-0001 Module Tested 1 PCS Honeywell HC900 DCS 900G02-0001 in good condition 1 PCS Honeywell HC900 DCS 900P01-0001 Tested 1 pcs Honeywell L404F1102 pressure controller 1 pcs HONEYWELL LSXA3K-1A Limit switch 1 pcs honeywell R7849A1023 1 pcs honeywell R7861A1026 Protection relay 1 pcs honeywell TBC1800A1011 1 pcs honeywell V5011P1038 1 PCS NEW Honeywell Pressure Switch SN3-280-LED 1 PCS New IN BOX Honeywell Air Valve Actuator D20010 D20010 1 PCS NEW IN BOX Honeywell Flame Monitor R4343D1017 1 product rating- 1 PC New Honeywell R7861 A 1026 Self Check Ultraviolet Flame Amplifier In Box 1 product rating- 1 pcs Honeywell L404F1102 pressure controller 1 product rating- 100% Tested Honeywell 5010 XC5010C 60-Day Warranty [1ix] 1 product rating- 1PC Brand New Honeywell R7861A1026 Burner Controller DHL free shipping 1 product rating- 1PC New Brand Honeywell R7861 A 1026 One year warranty R7861A1026 Fast Delivery 1 product rating- 1PC New Honeywell 3310G scanning platform fixed barcode scanner free shipping 1 product rating- 1PC New Honeywell L404F1094 1 product rating- 1PC New Honeywell R7861 A 1026 Self Check Ultraviolet Flame Amplifier R7861A102 1 product rating- 1PC New Honeywell R7861A1026 Burner Controller 1 year warranty 1 product rating- 1PC New Honeywell R7861A1026 Burner Controller 1 year warranty#XR 1 product rating- 1PC New Honeywell R7861A1026 Burner Controller one year warranty fast delivery 1 product rating- 1PC New Honeywell R7861A1026 Burner Controller one year warranty free shipping 1 product rating- 1PC New Honeywell RF receiver module spare parts W8665E1000 1 year warranty#XR 1 product rating- 1PC New in box Honeywell R7861 A 1026 One year warranty R7861A1026 Fast Delivery 1 product rating- 1PC New LSN1A honeywell limit switch 1 product rating- 1pcs New Honeywell Pressure Controller L404F1102 1 product rating- Brand New Honeywell R7861A1026 Burner Controller DHL free shipping 1 product rating- EXCEL.
