[#1] 降壓/隔離牛 應否長開 每次通電的時候,都有一下好響的"咚"聲和震動,要好幾秒鐘才穩定,請問各位C Hing, 你們的降壓/隔離牛會否長開 1)隻牛長開,多少會耗電,損耗 2)不用關上,每次開機都有"咚"聲和震動,是否更傷 |

[#2] 降壓/隔離牛 應否長開 請問你的牛有沒有'hum" 或 嗚嗚 聲 ? |

[#4] 降壓/隔離牛 應否長開 我估沒有。但我的嗚聲很大,影響聆聽,正想辦法解決。 |

[#5] 降壓/隔離牛 應否長開 C-Hing, have you tried the brand CSE? It is high quality isolation transformer that should never make "hum" sound. |

[#7] 降壓/隔離牛 應否長開 Apprentice 兄: 我也聽過這品牌名,但我住在加拿大,難以購買。Search 過 internet, 打算on-line 買PS Humbuster. CSE 方面,有何建議? |

[#8] 降壓/隔離牛 應否長開 如沒有發熱情況,應可以長開,小弟的cse2000火牛,差不多全年不關機,反而常開常關,對牛似乎不好,至於牛會(小小)發聲,及開機嘭一聱,小弟都試過,有電工指是正常的,以上只是小弟的小小意見,勿見笑,謝謝 |

[#9] 降壓/隔離牛 應否長開 隔離牛長開會唔會好食電? 2000W = 長用2000W?? 當然不是,如果沒有接電器,自身的損耗大概10W, 視乎你隻牛的質量 最後修改時間: 2009-12-31 12:02:26 |

[#11] 降壓/隔離牛 應否長開 以我初級的知識都知道, 2000W的牛只是最高輸出功率,不等於運作/消耗功率, 假如火牛是完美的,輸入端插電輸出空載是不會耗電的, 輸出端接200W的電器, 全系統的耗電量就是200W 我的問題是,沒有一個牛是完美的,在有大概10W損耗的情況下,各位朋友是繼續長開還是不用就斷電(要忍受開機時候的聲音+震動) |

[#12] 降壓/隔離牛 應否長開 there's usually a small bulb for these kind of transformers, and when powered on only that bulb is using electricity, so no need to worry about high utility bill. on the other hand, my step down transformer takes at least 6 hours to warm up properly and give nice sound, it sounds terrible when cold, so you need to consider that aspect too. |

[#13] 降壓/隔離牛 應否長開 The HUM noise is due to the core EI plate vibration, no way to cure. Get a sound proof box to cover it. Another way is to dip the transformer with epoxy! 最後修改時間: 2009-12-31 15:43:39 |

[#14] 降壓/隔離牛 應否長開 長開消耗的祇是牛產生的熱能,越熱越耗電。 有時較大噪音是由於機箱受牛震引發的噪音。damp下會得。 |

[#17] 降壓/隔離牛 應否長開 A transformer still has magnetization loss and eddy current loss even at no-load, though quite small. Can feel the warmth. Not simply supplying a lamp bulb. |

[#18] 降壓/隔離牛 應否長開 So it is normal that step-down transformers will create "de de"sound during operation? I am using 2 transformers(Hoi Wan & Patronics) currently for my stereo & AV systems. They both disturb me with "de de" sound. Very annoying!! Any more similar products without that noise? Pls recommend. |
