The frequency in Hz is governed by the speed of a generator. The voltage is governed by the winding and types of connections of these windings.
By using step-down transformer
3 amps
Voltage x Current = Power So Power / voltage = current Now you do the math
You may or you may not. It all depends on the task you are using the motor. If speed is not a concern for you then you may, but for sensitive systems where changes in motor speed affects the system then you may not. The reason is that the frequency of the power supply affects the motor speed. Frequency is directly proportional to speed.
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
The maximum power consumption of the appliance when operating at 230V 50Hz is determined by multiplying the voltage (230V) by the current (in amperes) that the appliance draws. This calculation will give you the power consumption in watts.
Seeing that "130VA" on the label, you should assume that there should be 130 watts of mains power available to operate the instrument.
It is not advisable because the motor would run 20% faster which might produce damaging overpressure in the thermal circuit.
The power adapter need 230v, 50Hz supply

To convert 1000W at 24V DC to an equivalent wattage at 230V AC, you can use the formula P = VI, where P is power, V is voltage, and I is current. First, calculate the current at 24V DC using P = VI. Then, use this current with 230V to find the equivalent power at 230V AC.
230v power supply .................it requires 12watts......
how many watts aew needed to power a 110 volt tv at 1.30 amp
Voltage x Current = Power So Power / voltage = current Now you do the math
Power = V A = 1,610 watts
Your electrician is correct on this. However, the pump is designed for 230V and will use less electricity, thus saving money if wired for 230V. Yeah, if you have to rewire for 230 V then it would be more expensive until your savings had consumed or offset the expense.
