If you exceed this limit, the transformers will overheat. Also, the current loading on the 3-phase, 480V primary system will be unbalanced on a per-phase basis. And, the 380V to 400V, 3-phase line-to-neutral voltages won’t be symmetrical, because the neutral “zero” point is determined by the original 480V supply.
How to convert watts to amps. To convert watts (electrical power) to amps (electrical current) at a fixed voltage, you can use a variation of Watt's Law formula: Power = Current × Voltage (P = IV). By working backwards, we get the equation: amps = watts ÷ volts, which can be used to convert watts to amps. Look at the table of motor kW to cable size chart. The chart is prepared based on the direct online start and star-delta starting. Note that, using aluminium cable for low rating motor up to 1.5kW/2HP motor is not recommended. Here 2R indicates Two Run cables. The cable size chart is suitable for both single-phase and three-phase. 72V to 110V DC/DC converter, 120W. The DY120-DD110-72 is a 110V converter of 120W. The converter can convert 72V to 110V DC and supply a DC current of 1,1A to 1,35A. In. 72VDC. Input range. 61.2 - 82.8VDC. It is a conversion calculator which changes the current in Amps (A) and the voltage in volts (V) to power results in Kilowatts (kW). The first step is to select the current type. It can either be Direct Current denoted as (DC) or alternating current (AC).
generator produce 220v AC 3phase (3Wire) bridge rectifier transform 220v 3 phase to 340v DC (2Wire) my goal is to get 220v AC 1 phase so with 2 wire. for this I need to find a way to convert 3 phase Ac 220v to 1 phase AC 220v. or 340V DC from the bridge rectifier to 220V AC for home appliances (Europe) I hope it is easier to understand.
