providing twice the power reserve Explanation: Kuznetsov's R>E Polytechnic Dictionary translates запас мощности as "power reserve", but this is probably for an electrical context. "Reserve powers" also sounds OK to me |

peer agreement (net): +1providing twice the performance reserve Explanation: but IMO "providing twice the performance" would also do |

double power margin/double power reserve Explanation: http://en.wikipedia.org/wiki/Power_margin From Wikipedia, the free encyclopedia In telecommunication, the power margin is the difference between available signal power and the minimum signal power needed to overcome system losses and still satisfy the minimum input requirements of the receiver for a given performance level. System power margin reflects the excess signal level, present at the input of the receiver, that is available to compensate for (a) the effects of component aging in the transmitter, receiver, or physical transmission medium, and (b) a deterioration in propagation conditions. Synonym system power margin. -------------------------------------------------- Note added at 44 mins (2009-04-28 19:28:39 GMT) -------------------------------------------------- One more explanation for POWER MARGIN: It's an excess capacity in a UPS system. For example, if a PC uses 400 watts and the UPS provides 600 watts, there are 200 watts of power margin. http://encyclopedia2.thefreedictionary.com/power margin -------------------------------------------------- Note added at 55 mins (2009-04-28 19:40:07 GMT) -------------------------------------------------- Выбор ИБП (UPS selection) При работе ИБП на предельной мощности возможны отключения из-за перегрузки, кроме того, время автономной работы будет минимальным - всего несколько минут. Поэтому при выборе модели лучше предусмотреть достаточный запас, чтобы загружать ИБП не "под завязку", а только на 30-70 %. Зависимость времени работы от потребляемой мощности нелинейна, и это дает дополнительный выигрыш. Так, двойной запас по мощности (50 % от максимальной нагрузки ИБП) увеличивает время автономной работы не в два, а в 3-5 раз. http://paper.key.ru/arts/276/ -------------------------------------------------- Note added at 1 hr (2009-04-28 19:54:48 GMT) -------------------------------------------------- Example: The rated power/capacity should be 500 watts, but the actual one is 1000 watts. The power margin (power reserve) is 500 watts. |
