a power supply must deliver xxx watts to a load the transformer must match the load capabilities plus its own loss
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.

No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN
The Baldor TS25 trailer-mounted generator has a standby power rating of 25 kW (kilowatts). This rating indicates the maximum power it can provide during emergency or backup situations. It’s designed for reliable performance in various applications, including construction sites and emergency power supply. Always consult the manufacturer's specifications for detailed information.
Power supplies don't have a speed rating.

The maximum voltage rating for equipment that can be safely operated with a power supply of 230 VAC is typically around 250 volts.
It is generally not recommended to use a power supply that exceeds the current rating of the device you are powering. In this case, using a 24V 3A power supply instead of a 24V 2.3A could potentially overload the device and lead to damage or malfunction. It is safer to use a power supply that matches or slightly exceeds the current rating of the device.

The power supplied by a three-phase supply, or any supply come to that, is determined by the LOAD, and not by the supply. So you must look at the data provided on the equipment's nameplate to find out what its power rating is.
Minimal. The phone should have a power rating on it somewhere, most likely on the bottom or on the power supply.
Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.
The size of an Uninterruptible Power Supply (UPS) is typically specified using its capacity rating, measured in Volt-Amperes (VA) or kilovolt-amperes (kVA). This rating indicates the maximum load the UPS can support while providing backup power. Additionally, the rating may also include the output power factor, which helps determine the actual wattage that the UPS can supply to connected devices.
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
