風機泵類商業(yè)應用的最佳選擇
羅克韋爾自動化旗下艾倫-布拉德利PowerFlex400變頻器擁有眾多內(nèi)置特性支持變頻器與樓宇控制系統(tǒng)之間的無縫連接，大大方便了風機和泵類在商業(yè)領域的應用（如HVAC）?？蛇x功率范圍從7.5HP到100HP（電壓等級為交流380V到480V時）和7.5HP到50HP（電壓等級為交流200V到240V時）。PowerFlex400是為滿足全球OEM、分銷商和最終用戶對于靈活性、節(jié)省空間和使用方便的要求設計的。明智地選擇PowerFlex 400高效率低成本變頻設備，為您的風機和泵類運用提供完美的速度控制。
特性：
· 集成的PID控制器可自動調(diào)整輸出頻率，調(diào)節(jié)過程變量。
· 三個可編程的跳變頻率段防止了變頻器在共振頻率中連續(xù)運行，避免機械損壞。
· 可選的風扇/泵類曲線針對離心風扇和泵類負載提供降電壓模式。
· PowerFlex400變頻器獨特的休眠功能在系統(tǒng)需求降低到預先設定標準時，自動關閉機器；當系統(tǒng)需求增加時，自動起動機器。
· 針對某些無人看管運行環(huán)境，系統(tǒng)斷電而后恢復時，變頻器將自動重起運行。
· Freeze/Fire和Purge等特定輸入，可直接連接到消防等緊急安全系統(tǒng)。
