Rockwell Automation ups power ratings to 350 hp in Allen-Bradley PowerFlex AC Drives

羅克韋爾自動(dòng)化加大A-B PowerFlex 交流驅(qū)動(dòng)的額定功率至350馬力

High-performance AC drives offer flexible, cost-effective speed control in a variety of variable torque fan and pump applications

高性能AC驅(qū)動(dòng)為各種變矩風(fēng)扇和泵應(yīng)用提供了靈活、高性價(jià)比的速度控制

Milwaukee, Jan. 15, 2007 — To help HVAC contractors and engineers efficiently apply variable frequency motor control to a broader set of motor-driven applications, Rockwell Automation has expanded its Allen-Bradley PowerFlex 400 HVAC drives offering to include increased power ratings up to 350 horsepower. Optimized for commercial fan and pump applications, PowerFlex 400 AC drives feature built-in network connectivity for seamless integration into building automation systems, as well as flexible packaging options for easy installation and startup.

密爾沃基1月15日消息——為了幫助高壓交流電（HVAC）承包商和工程師有效地將變頻電機(jī)控制應(yīng)用到更廣范圍的電機(jī)驅(qū)動(dòng)應(yīng)用中，羅克韋爾自動(dòng)化擴(kuò)大了其艾倫－布拉得利（A-B）PowerFlex 400 HVAC驅(qū)動(dòng)的供應(yīng)，包括了額定功率達(dá)350馬力的增強(qiáng)型號(hào)。

“Applications involving large centrifugal loads and changing flow rates, such as air handlers, cooling towers and chillers, are prime targets for significant energy savings,” said David Mantey, product marketing manager, Rockwell Automation. “PowerFlex 400 variable frequency drives deliver optimum speed control to help users improve air handling efficiency, optimize energy consumption and reduce overall energy costs.”

羅克韋爾自動(dòng)化產(chǎn)品營(yíng)銷經(jīng)理David Mantey表示:"涉及大型離心負(fù)荷和變化速率的應(yīng)用，例如空氣處理機(jī)、冷凝塔和冷凝器，是大量節(jié)省能源的主要目標(biāo)。PowerFlex 400變頻驅(qū)動(dòng)提供了最優(yōu)的速度控制，幫助用戶改善空氣處理效率，優(yōu)化能源消耗，減少能源總體成本?！?/P>

Ease of Integration. An integral RS485 communications interface provides support for most standard building automation networks, including Modbus RTU, N2 and Siemens P1-FLN. These protocols are parameter selectable and require no additional hardware or software. For expanded communication capability, optional add-on modules provide connectivity to LonWorks and BACnet networks.

集成容易。一個(gè)完整的RS485 通信界面對(duì)幾乎所有的標(biāo)準(zhǔn)樓宇自動(dòng)化網(wǎng)絡(luò)提供支持，包括Modbus RTU，N2和西門子P1-FLN。這些協(xié)議屬于參數(shù)可選擇協(xié)議，而無(wú)需額外的硬件或者軟件。對(duì)于擴(kuò)大的通信能力，可選購(gòu)的附加模塊提供了連接LonWorks和BACnet 網(wǎng)絡(luò)的能力。

Built-In Intelligence. PowerFlex 400 HVAC drives feature an embedded PID controller that automatically adjusts the output frequency to maintain a process variable. Three programmable skip frequencies and bands prevent the drive from running continuously at resonant speeds, which could cause mechanical breakdowns. Selectable fan and pump curves provide reduced voltage patterns for centrifugal fan and pump loads.

內(nèi)置智能性。PowerFlex 400 HVAC驅(qū)動(dòng)擁有一個(gè)嵌入式PID控制器，可以自動(dòng)調(diào)節(jié)輸出頻率，維持一個(gè)過(guò)程變量。三個(gè)可編程跳躍頻率和波段預(yù)防了驅(qū)動(dòng)連續(xù)以會(huì)導(dǎo)致機(jī)械故障的共鳴速度運(yùn)轉(zhuǎn)?？蛇x擇的風(fēng)扇和泵曲面為離心風(fēng)扇和泵負(fù)荷減少了電壓譜。

A sleep function allows the drives to be cycled off when the system demand drops below a preset level, and restarted automatically when the demand increases. For applications that require unattended operation, a “Start At Power Up” function allows the drives to resume running once power is restored after a power outage. Users also can connect the drives to fire and safety systems via freeze/fire and purge inputs.

睡眠功能允許驅(qū)動(dòng)在系統(tǒng)需求降到一個(gè)預(yù)設(shè)級(jí)別之下的時(shí)候就停止運(yùn)行，而當(dāng)需求增加的時(shí)候又自動(dòng)重新啟動(dòng)。對(duì)于需要無(wú)人操作的應(yīng)用，”連電即啟動(dòng)“功能使得驅(qū)動(dòng)一旦在停電之后電力恢復(fù)的時(shí)候可以重新運(yùn)行。用戶也可以通過(guò)冷凍/火和凈化輸入將驅(qū)動(dòng)連接到防火以及安全系統(tǒng)。

Disconnect and contactor bypass packages simplify installation and startup by combining operator interface, control, communications and power options in preconfigured assemblies. Contactor bypass packages come with three contactors, allowing drive test functionality and drive isolation when in bypass mode. Users can easily program, monitor and control the drives using Allen-Bradley DriveExplorer and DriveTools SP software.

斷開(kāi)和接觸器迂回包通過(guò)結(jié)合操作界面、控制、通信以及電源選項(xiàng)，在預(yù)配置裝配中簡(jiǎn)化了安裝和啟動(dòng)。電流接觸器迂回包帶有三個(gè)接觸器，使得驅(qū)動(dòng)在迂回模式中，測(cè)試其功能和驅(qū)動(dòng)絕緣性。利用A-B的DriveExplorer和DriveTools SP軟件，用戶可以輕易地計(jì)劃、監(jiān)測(cè)和控制驅(qū)動(dòng)。

A UL 508C plenum rating gives PowerFlex 400 drives further installation flexibility by allowing them to be mounted directly inside an air handling system, such as ventilation ductwork. The drives also meet seismic requirements of the 2003 International Building Code as specified by AC156. NEMA/UL packaging options include enclosures to meet both indoor and outdoor application requirements.

UL 508C的高壓級(jí)別使PowerFlex 400驅(qū)動(dòng)具有更大的安裝靈活度，它們可以直接安在一個(gè)空氣處理系統(tǒng)的內(nèi)部，例如通風(fēng)管道系統(tǒng)。該系列驅(qū)動(dòng)同樣符合在AC156詳細(xì)說(shuō)明的2003國(guó)際樓宇代碼的地震要求。NEMA/UL包裝型號(hào)帶有外殼，適合室內(nèi)和室外的應(yīng)用要求。
