45 kVA three phase solid state (static) frequency converter, converting 50Hz to 60Hz, 400Hz with pure sine wave output, compatible with 3 phase 220V - 240V, 380V, 400V - 480V power system. Specification. 900*800*1200 mm. 3 Phase 4 Wire: Wye Type 190/110, 200/115, 208/120, 220/128, 230/132, 240/139V ±10% (option *) The Amps to kVA Calculator is a tool that helps to convert the current measurement in amps (A) to apparent power measurement in kilovolt-amps (kVA) based on the voltage in volts (V) and the phase of the current. The calculator uses the following formulas: 1-Phase: S(kVA) = I(A) × V(V) / 1000 For example, a power supply may be 90% efficient producing 100 watts to components with 110v input, but may be 92% efficient producing those 100 watts with 220v input. Computer power supplies that have a wide input range (for example 90v AC ..250v AC) do this by having an Active PFC circuit which boosts whatever input voltage you have to around Transformers. Raise or lower voltage to meet the needs of an individual circuit. 189 products. Phase Converters. Generate three-phase output power from a single-phase input. 11 products. Choose from our selection of AC to AC voltage transformers, including over 200 products in a wide range of styles and sizes. In stock and ready to ship. Some of these deviations can make your three-phase voltages reach 440v, but other than this normally your 3-phase voltage is not 440v. In a 3-phase system, the voltage between any two phases is greater than a single-phase voltage by a factor of √ 3 or 1.73 roughly. That means if your single-phase voltage is 120v like in the US or Canada, your Anonymous. May 25, 2007. #1. I need to build a enclosure to house a 3ph speed drive. To dissipate the heat inside, I will need to install 2 units of panel fans which requires 230V single-phase to run. However, only 3ph 400V w/o neutral supply is available. So, I was thinking of putting in a 400V to 230V transformer, but understanding that the 6d4RsA6. 1) how to convert the lathe 2) how to get the three phase. You might specify what you want, the conversion, the 3 phase, or both. And, maybe some comment about why you want the conversion, whether for better smoothness of operation, or for variable speed, and so forth. Some idea of the project budget is also good to know. GoHz 150 kVA static frequency converter for converting three phase 460V 60Hz to 415V 50Hz, 400V 50Hz, 420V 50Hz etc. Output voltage is adjustable from 0 - 520V three phase. -When the output is 400Hz, the load capacity can only reach 50% of the rated capacity. -When the output is ≤120Hz, the load capacity can reach 100% of the rated value. The kW per winding (single phase) has to be the total divided by 3. Similarly a transformer (with three windings, each identical) supplying a given kVA will have each winding supplying a third of the total power. To convert a three phase problem to a single phase problem take the total kW (or kVA) and divide by three. In this video, I try to explain to you what you have to do to run such motor from a single phase 8. Any voltage can be supplied as three-phase. Various voltages are more popular in various parts of the world and in various usage situations. In the USA, 220-240 volt, three-phase has been used to some extent for small industrial installations, but 480 volts is much more popular for three-phase installations. Share. If you run a 400v 50 Hz machine at 400v 60 Hz, the motor speed is 17% slower, the amp draw is 17% higher, the power output is 17% lower, and the motor will overheat because the motor cooling fan is not running at proper speed. At 380v, all the above is worse by 5%. For 60 Hz use, you need 460 volts.
