What is the acceptable voltage higher than 480v for a 480v inverter?

The voltage range should be marked on the case but without that information a 5% increase can be assumed, so 504 v.

What is the minimum acceptable reading for magger test for 480v motor?
if check voltage is 2000v then acceptable range is 400
What is the voltage for each leg on a 480v 3-phase pannel phase to neutral?
Only one neutral conductor is typically in a 3 phase panel.
Is there any advantage of 208V vs 480V three phase?
208 v. equipment is a little smaller and cheaper, and 208v. is slightly safer to use. However, 480v. runs on half the amperage 208v. equipment does, which means equipment or devices cost almost 50% less to operate. With respect to energy consumption, the answer above is incorrect. It is true that equipment that operates at 480v does operate at roughly half the amperage vs. 208v, however, it operates at over twice the voltage. Your local power company charges you per kilowatt hour (voltage x amperage), not on amperage alone. Example, a 208v motor that draws 10 amps would consume (208v x 10a) 2.080 kilowatts per hour. The same motor on 480v would draw roughly half, 4.3 amps (480v x 4.3a) and would also consume 2.080 kilowatts per hour. So in terms of power consumption, they are virtually the same. The main reasons one would opt for higher is the fact that you can install smaller wire and you can run longer distances. It's a ratio that is directly proportional (at least with electric motors/inductive loads). If you were comparing a 240v motor to a 480v motor the ratio would be exact, if a 480v motor draws 5 amps, the same motor on 240v would draw 10 amps.
How many output amps is a 75 kva 208v-480v?
1kw=1.25kvaby this relation 75kva=60kwp=1.732*380*I*1I=60000/1.732*380*1I=91AmpsCommentPower factor is irrelevant to this question. You don't need to convert the kV.A rating to kilowatts, simply divide 75 000 V.A by (1.732 x 380). The answer is 114 A.This, of course, assumes that the question refers to a three-phase generator and that 380 V is the line voltage.
If the output voltage from the transformer if primary coil 60 turns of wires and secondary coil 4 turns of wire is 32 v what is the input voltage?
Divide the amount of turns in the secondary into 32 V and you'll get 8. Now multiply 8 times 60 turns and you'll get 480V.
What is the minimum acceptable reading for magger test for 480v motor?
if check voltage is 2000v then acceptable range is 400
Is 480 rms or peak voltage?
When people talk about 480V systems, they mean 480 is the RMS voltage.
What is the nominal voltage of a 150 kW 480 v generator?
480V.
How is line voltage computed in a wye three phase cofiguration?
Line voltage equals phase voltage multiplied by the square root of three. a.k.a. E l = E p X 1.73 In a 3 phase 480v system the phase voltage is 277v. Therefore E l = 277 X 1.73 = 480v
Power a 415volt motor with 480volts?
in low voltage connection in wye (star conncetion) 415v high voltage connection in delta 480v
Is 5 voltage drop acceptable for 480v motors?
NEC recommends a maximum 3% drop for branch circuits. 5 volts is well within this range. So, yes 5v drop is normally fine, unless the motor manufacturer has a more stringent requirement.
A 100 amp 3 phase power supply is good for how many total amps?
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
What is Supply voltage for heavy industry?
480v for the small motors,1340v mediums. 3160v for the pretty big ones..and a few others in between
How do you convert 380v 3 phase to 220v 3 phase?
Mathematically, just divide 480 by the square root of three. Electrically, 480V refers to the line-to-line value of a three phase system. For example, measure the voltage across A-phase and B-phase and you'll get 480V. 277V is the line-to-neutral value. Measure the voltage across A-phase and the neutral conductor and you should get 277V.
What is the voltage for each leg on a 480v 3-phase pannel phase to neutral?
Only one neutral conductor is typically in a 3 phase panel.
Can you use a 480V 60hz deep fryer on a 380v 50hz power supply stepped up to 480v 50hz by a transfomer?
It is an extremely expensive way of utilizing the deep fat fryer. You should look into changing the heating coils in the fryer to utilize the new voltage. That said it can be done.
