![]() ![]() I would even question if some of the amps he is mentioning have enough output devices to support that. It seems like physics alone dictates that 10kw from a normal household outlet is next to impossible. This method may be too inaccurate or too slow to get an accurate reading, but doing this, I've never even seen 100 amps through the A/C lines when it does trip a breaker. Now this probably is a very flawed test, but I have used an AC Inductive current measuring meter from Fluke to measure the amount of current that is drawn at startup before of many of my amplifiers. His amp uses a switchmode supply, now those don't ever seem to have much reserve capacitance, so am I right to think that the outlet would need to supply most of the current? Wouldn't even a brief peek at 150-200 amps be enough to not only trip the breaker but potentially melt the insulation on 14 guage Romex? Last amplifier I used rated at even 5,000 watts RMS used 240 lines because of the current problems. More current at 100 volts, which is probably closer to the rails of such an amp, but I don't know. I'm curious, because he is now saying he tested his amp to 18,000 watts and is running more than one of them, is that even possible for peaks? I mean, it would require over 150 amps of current at 117 volts. ![]() I said that, first, I did it because I like to DIY, second, I don't like proaudio amplifiers because of the fans, and third, I doupt highly he was getting 10,000 watts from his amplifiers. He was argueing that I wasted my money and should have purchased a used QSC or Crest amplifier, becuase I could have had 10,000 watts for 500 dollars, or whatever. I was talking to someone on another forum about my amp project. Conversion chartĪdditionally, here is a chart showing the conversion of various power ratings at different electrical phases, considering a 0.8 power factor and a system voltage of 120V.I dont want or need this, its a curiosity question. Simply input the details, such as the kW rating and system voltage for DC connections, and consider the power factor rating for single and three-phase electrical systems. \Īside from these manual calculations, you can use an online calculator to easily determine the amp rating of a specific unit. Suppose you want to use a 10-kW unit in a 220v system, the calculation will go like this: To know how many amps is 10kW in DC connection, you need to consider the voltage rating of the system. ![]() For DC connections: Amps = (1000 x kW) / Volt Let’s explore the formulas and steps for each type: 1. The conversion and calculation process for converting 10 kilowatts (kW) to Amperes (Amps) depends on the type of electrical system: DC, AC single-phase, or three-phase. For AC single phase: Amps = 1000 x kW / (PF x Volt)Ĭonversion Formula and Calculation Process Conversion Formula and Calculation Process. ![]()
