厂方的一些说明:
This means the PowerLab 8 may
draw up to 1600W from the input power supply.
To take advantage of PowerLab 8’s full power capability, the power source should be
26.35V DC (higher voltage does not improve output power), and capable of delivering a
minimum of 60A to PowerLab 8’s input. Per Ohm’s law, 26.35V x 60A = 1581W. However,
it is generally not advisable to pull 100% of available power from a DC power
supply. Therefore, if you want to attain 1344W of output power to an 8s Li battery, the
power supply should be capable of 1700W or higher for best results.
虽然以前的理解不是很合理(高电压并不能提升功率),官方这样分析的话,最好是26V60A的电源,结合价格因数和规格因数,还是买30V50A是最好的选择。
价格因数:目前查50A是一个规格级别,大于这个规格的价格上升很大。
规格因数:目前大部分的电源,以30V可调的规格比较多选择。 |
