The main reason that a transformer overheats is too much current for the transformer design. So my guess is that you have more load than the transformer was designed for. So my answer would be not powerful enough.
You are not actually worried about the "power" of the device. You could use a 15 amp power supply on a device that needed a .015 amp load.
What you are REALLY waning to make sure of is that the desired voltage is matched. A 12 volt D.C. supply should only be used with systems that need 12 volts D.C. To use anything else causes issues. Too low of a voltage gives you brown out issues and too high of a voltage could cause you to draw so much current you burn the device up.
What else can I help you with?
What usually happens at consumer end when the current carrying capacity of transformer is exceeded?
What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.
What is the function of fins in transformer?
Fins in a transformer serve as a heat dissipation mechanism to help regulate the temperature of the transformer. Transformers can generate a significant amount of heat during operation due to electrical losses, and the fins provide a larger surface area for heat to dissipate into the surrounding air. This helps prevent overheating and ensures the transformer operates within its temperature limits, ultimately improving its efficiency and longevity.
Why are transformer more efficient that rotating electric machines?
Because the electrical parts of a transformer do not move / rotate.
What is the reason to use open circuit and short circuit methods to find Transformer losses?
The transformer can be tested on open and short circuit to find the iron losses and copper losses separately, which uses a fraction of the power than having to run the transformer on full-load.
What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
What are the causes of overheating of distribution transformer?
poor cooling mechanisms, and overloading.
Why is it better to determine the efficiency of the transformer indirectly rather than by loading it?
It is better to determine the efficiency of a transformer indirectly through measurements and calculations because direct loading can cause overheating and damage to the transformer. Indirect methods are safer, more accurate, and do not risk the operational integrity of the transformer.

How do you measure a temperature in transformer?
Temperature in a transformer can be measured using devices such as thermocouples, resistance temperature detectors (RTDs), or infrared thermometers. These devices can be placed in different parts of the transformer to monitor temperature and ensure it stays within safe operating limits. Regular monitoring of transformer temperature is important to prevent overheating and potential damage to the equipment.
What type of transformer will convert 120V-60HZ US into U.K.voltage?
The standard residential nominal voltage in the UK is 230 V (-6%/+10%). So, for the purpose of selecting a transformer, a 1:2 ratio, 120/240 V, transformer will be an appropriate choice.The capacity (volt ampere rating) of the transformer must match or exceed the power rating of the proposed load. You should be aware, though, that transformers will not change the frequency of the supply, only its voltage.Another thing to be considered is the transformer's country of manufacture and where you intend to use it. For example, if the transformer is manufactured in the US, then it will be designed to operate at a frequency of 60 Hz.On the other hand, if it is manufactured in Europe, then it will be designed to operate at 50 Hz.A transformer designed to operate at 60 Hz will overheatif it is operated at 50 Hz, whereas a transformer designed to operate at 50 Hz will operate without overheating if operated at 60 Hz.This means that you will be able to operate a European transformer in the US without any difficulty, but operating a US transformer in Europe will result in overheating -unless it is operated BELOW its rated primary/secondary voltage.So if you intend operating a US made transformer in Europe, then you should obtain a 1:2 ratio transformer, but one rated at, say, 240/480 V. This will then operate without overheating at 120/240 V.
What is the function of a heater transformer in an electrical system?
A heater transformer in an electrical system is used to step down the voltage from the main power supply to a lower voltage suitable for powering heaters. This helps to regulate the temperature and prevent overheating in the system.
What is the result when 3 kva power requirement is being supplied by 250 kva transformer?
The result is that the transformer runs cool and contented. The '250 KVA' rating on the transformer is its maximum ability to transfer power from its input to its output without overheating, NOT an amount of power always running through it. If the 3 KVA load happens to be the only thing connected to the transformer at the time, then only 3 KVA flows into the transformer from the primary line, and only 3 KVA leaves the transformer secondary.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
Why are transformer more efficient that rotating electric machines?
Because the electrical parts of a transformer do not move / rotate.
What is mean core saturation?
Core saturation occurs in electrical transformers when the magnetic flux in the core reaches its maximum limit, resulting in a decrease in efficiency and potential overheating. It can be caused by excessive current or voltage in the transformer, leading to distortion in the output waveform and potential damage to the transformer.
What is the reason for conduct SFRA tets in transformer?
To detect problems with the core shifting or grounding problems
