2006年3月8日 · Thus, you will see distro units with 9 or 12 single phase sockets on them and most will be marked as phase 1, phase 2 and phase 3. Often they will be marked with colour (ie, red 1 or white 3) or with numbers (ie, 1-1 or 2-3). Three phase generally carries more current and is used in lighting and sound because you can power up more

2014年5月5日 · If you have an industrial connector that provides three phase power - I would expect that it would have more than three pins. Three phase means that you have three hot legs. Some motors are designed to work from just three phases ( with no neutral in the connector) but my expectation is that you would have a ground connection in any kind of ...

2006年8月31日 · On the ditribution side there were two 3 phase outlets. Also there were three double socket outlets, wired one to a phase. There was also all the appropriate circuit breakers included. It would probably cost $400 - $500 to have made as the three phase plugs, sockets are probably a $100+ each. There are also pre-made ditribution boxes to do this.

2010年2月3日 · The answer varies by type of three phase.... WYE is the most common, providing 208 V phase to phase, and 120 V from any phase to neutral. Only three phase motors will care about phase order. DELTA is 240 V phase to phase, and two of the phases are 120 V to neutral. The third phase is 208 V to neutral!!

2012年11月12日 · If the phases are 120° apart, as they are on a three phase system, some cancellation is going to occur. The phases are 120° apart. The phases are 120° apart. Multiply 240 x the sine of 120° [0.866] and get 207.84; let's call it 208V.

2016年8月27日 · Phase is a relationship Polarity is a direction In some ways, "single phase" power is an oxymoron as there is no other phase to compare it to. Polarity is the direction of flow. Here's where things get fun! If you were educated in the 50s and 60s, you "knew" that electrons flow from the negative source to the positive side.

2008年9月8日 · 3 phase, 4 wire is intended for powering three phase motors on industrial machinery. It was never intended for providing 120 volt power. If you intend to continue using this piece of equipment, it needs to be converted to either a single phase, 4 wire service, or a three phase 5 wire service. As it is currently set up, this piece of equipment ...

2024年11月23日 · Audio signals are generally divided up into three categories -- mic, line, and speaker. A mic signal would come from any microphone. Some microphones like condensers need a little extra oomph from phantom power to amplify …

2017年4月16日 · Power to the dimmer must be cut. The dimmer is rated for 2.4Kw/ channel and 28.8Kw total, and is fed with a 100A 120/208 three-phase circuit . Each channel is loaded to 750W, well below the limits.

2024年12月7日 · The three source fours in the middle are S4JRs. No movers, no LEDs. We also have three booms a side that are in line withers 1-3. Each boom has 3 Pars and 1 profile at shin. These are how I've been providing colour at the moment as they are the only gels I can get to. All the top lights are uncoloured at the moment.
